Strengths

• All five visited spaces present and correctly named (Living, Entry foyer, Dining, Kitchen, Main hallway), with no invented rooms
• Correct room spine: Living at the street end, Dining behind it, Kitchen behind that, matching the camera sequence
• Hallway correctly modelled as a long corridor alongside the dining room and kitchen, entered from the foyer and continuing past the visited area
• Nearly all real openings captured: front door into the foyer, archway foyer→living, living→dining, dining→kitchen, hallway→dining, hallway→kitchen, kitchen→balcony
• Overall footprint (8 × 13 m) close to the true 7.6 × 14.1 m, and living-room size 6 × 3.5 m close to 5.9 × 4.3 m
• Balcony door correctly placed on the kitchen wall opposite the hallway; good appliance/furniture inventory

Errors

• Balcony omitted as a room, represented only as an exterior door
• Invented doorway between the entry foyer and the dining room (they do not touch in reality)
• Fireplace and arched window placed on swapped walls of the living room (fireplace should be on the short side wall, arched window on the street-facing long wall)
• Dining room oversized (6 × 5 m vs 4.5 × 3.5 m), making it the largest of the three main rooms instead of the smallest
• Kitchen's long axis transposed (6 × 4.5 m vs 4.5 × 5.3 m); all main rooms drawn the same 6 m width, losing the living room's extra width and the wider left-hand hall strip
• Foyer attached to the living room's short end rather than sitting beside its street-side/left portion with the exterior Entry

## Reasoning **Global orientation.** The model's plan has Living room top‑left, Entry foyer top‑right, Dining room middle‑left, Kitchen bottom‑left, Main hallway running down the right side. Rotating the model's plan 180° puts the Living room + Entry foyer at the bottom (street side), the Dining room above it, the Kitchen above that, and the hallway running up the **left** side beside dining/kitchen and continuing past the kitchen toward the unvisited bedrooms. That is exactly the truth's handedness — so it is a **180° rotation, not a mirror**. **Room inventory.** Living room, Entry foyer, Dining room, Main hallway, Kitchen — all five visited spaces are present and correctly named (the model sensibly merges Zillow's Entry + Foyer). The only visited space missing as a room is the **Balcony**, which appears only as a "kitchen → exterior" door. No invented rooms (no fake bedrooms/bathrooms). **Topology.** Very close to truth. Model openings: entry↔exterior front door ✓, entry↔living archway ✓ (truth: archway from foyer to living room), entry↔hallway door ✓, living↔dining ✓, dining↔hallway ✓, dining↔kitchen ✓, kitchen↔hallway ✓, kitchen↔exterior/balcony ✓. The only invented link is **entry foyer ↔ dining room**, which cannot exist in truth (the foyer and dining room don't share a wall). The camera path Foyer → Hallway → Living → Dining → Kitchen → Balcony is fully traversable in the model's plan. **Placement.** The core spine is right: three main rooms stacked in depth (Living at the street end, Dining behind it, Kitchen behind that), with the hallway as a long strip running alongside dining and kitchen and continuing off the visited area, reached from the foyer. The balcony door is on the kitchen wall away from the hallway — correct (truth: balcony off the kitchen's far/right wall). Minor deviation: in truth the foyer sits beside/above the *left* portion of the L‑shaped living room (front door from the Entry on the street side), whereas the model hangs the foyer off the living room's short end; and the hallway in truth is a wider left strip (3 m, containing bath/stairs behind it). **Proportions.** Footprint 8 × 13 m vs truth 7.6 × 14.1 m — very good. Living room 6 × 3.5 vs 5.9 × 4.3 — good. Kitchen 6 × 4.5 vs truth 4.5 × 5.3 — right area but the long axis is transposed. Dining room 6 × 5 vs truth 4.5 × 3.5 — notably oversized, making it the largest room when it should be the smallest of the three. Main rooms are all drawn a uniform 6 m wide, losing the fact that the living room is wider (it extends under the foyer/hallway) than dining/kitchen. **Features.** Fireplace, arched living‑room window, sofa/armchairs/coffee table, dining table, stove, refrigerator, sink, dishwasher, kitchen table, front door, mirrored closet in the foyer, balcony door — a rich and largely correct set. However, the fireplace and the arched window are on **swapped walls**: truth has the arched window on the street‑facing long wall and the fireplace on the short side wall at the far end; the model puts the fireplace on the far long wall and the window on the short end wall. Both are at the "far" end of the living room, so the error is a 90° wall confusion rather than a gross misplacement. The balcony is not rendered as a space, only as a door. ## Scores

## Description The floor is a roughly rectangular layout, approximately 8m wide (east-west) and 13m long (north-south), with rooms arranged along an east-side entry and hallway. The camera starts at the exterior front security gate, enters through the front door into the entry foyer, then explores the living room, dining room, main hallway, and kitchen, ending at a side exterior balcony off the kitchen. Rooms and connectivity: 1. **Entry Foyer**: A 2m × 5m space on the east side of the floor, with the front door (exterior) on its east wall. It connects to the living room via a wide arched opening on the north portion of its west wall, to the dining room via a standard doorway on the south portion of its west wall, and to the main hallway via a doorway on its south wall. A mirrored closet door is on the west wall, south of the dining doorway. 2. **Living Room**: A 6m × 3.5m room on the northwest side of the floor, adjacent to the entry foyer (east) and dining room (south). It has a large arched exterior window on its west wall, and a tiled fireplace with wooden built-ins on its north wall (meeting the window at the northwest corner). It connects to the entry via the archway (east wall) and to the dining room via a doorway near the east end of its south wall. Key furniture: a white sofa against the north wall (east of the fireplace), two brown swivel armchairs in front of the west window, a black rectangular coffee table between the seating areas, a tall brass floor lamp next to the fireplace, and a large potted plant in a white pot near the fireplace. A large textured wall art hangs above the sofa. 3. **Dining Room**: A 6m × 5m room south of the living room, west of the entry and upper hallway. It connects to the entry (northeast corner, doorway), living room (northeast, shared wall doorway), main hallway (east wall, central doorway), and kitchen (south wall, central doorway). It has a rectangular exterior window on its west wall. Key furniture: a round dining table with white upholstered chairs in the center, a dark console table with decor against the east wall, and framed wall art above the console. 4. **Main Hallway**: A 2m × 8m long corridor running south from the entry foyer along the east side of the floor. It connects to the entry (north end), dining room (northwest, doorway), and kitchen (mid-west, doorway). Further south along the hallway are doors to unvisited rooms (not included in the plan). 5. **Kitchen**: A 6m × 4.5m room on the southwest side of the floor, south of the dining room and west of the lower hallway. It connects to the dining room (north wall, central doorway) and main hallway (east wall, central doorway). It has an exterior window on its west wall (above the sink) and a side door on the west wall (south of the sink) leading to a narrow exterior balcony/side yard. Key appliances and furniture: stainless steel gas stove/oven (against north wall), stainless steel refrigerator (against west wall, north of the sink), a sink under the west window, a stainless steel dishwasher next to the sink, wooden upper/lower cabinets along all walls, and a small round wooden dining table with chairs on the east side of the kitchen. Uncertainties: Exact positions of small decor items are approximate. The hallway extends further south than the visited area, so its south end is placed at the limit of the seen space. The width of the arched entry to the living room is estimated based on typical interior arch dimensions.

Strengths

• All four visited spaces (Hallway/Foyer, Living, Dining, Kitchen) present, correctly named, nothing invented
• Camera sequence reproduced exactly: front door -> hallway -> living (archway) -> dining (wide archway) -> kitchen -> exterior/balcony door
• Living-Dining-Kitchen correctly stacked front-to-back with the living room on the street side and the hallway alongside on the correct side
• Balcony door placed on the kitchen wall away from the hallway, matching the real balcony position
• Overall footprint 7 x 13 m is very close to the true 7.6 x 13.4 m visited area; dining and living sizes near-correct

Errors

• Fireplace placed on the hallway-side wall of the living room instead of the far side wall
• Living-room (arched) window put on the far side wall (where the fireplace really is) rather than on the street-facing end
• Hallway drawn as a short 2 x 4 m stub, so its openings to the Dining Room and Kitchen and its continuation to the bedrooms are missing
• Entry/Foyer not distinguished (front door enters the end of the corridor rather than a foyer beside the living room)
• Balcony omitted as a room; kitchen slightly too shallow and all three main rooms given identical width though the living room is really wider

## Reasoning **Orientation.** The model stacks Living room (top) → Dining room (middle) → Kitchen (bottom), with the Hallway at the top-left beside the living room and the front door on the hallway's top (outer) wall. Ground truth has the street-facing Living Room/Foyer/Entry at the *bottom* of the page, Dining behind it, Kitchen behind that, and the hallway running up the *left* side. So the model's plan is flipped along the depth axis (a mirror about the horizontal axis): the room order is reversed front-to-back while the hallway stays on the same lateral side. Under a pure 180° rotation the hallway would have to be on the right, so this is a **mirrored** rendition, which is permitted; the internal arrangement is what matters. **Room inventory.** Hallway, Living room, Dining room, Kitchen are all present and correctly named — the four spaces the camera actually walked (Foyer is effectively absorbed into the "Hallway", which is defensible since Zillow itself merges the Foyer into the Living Room polygon). The Balcony is not drawn as a room, only implied by a "door to exterior" in the kitchen; the Entry is likewise only a front door. No invented rooms. **Topology.** The camera sequence Foyer/Hallway → Living → Dining → Kitchen → Balcony is reproduced exactly: exterior door into Hallway, archway Hallway→Living, wide archway Living→Dining (matching the real wide opening between them), opening Dining→Kitchen, and a door Kitchen→exterior on the far (right) wall where the real balcony is. That is the whole visited chain correct. Losses: the real hallway is a long 13 m corridor that also opens onto the Dining Room and the Kitchen (and continues to bedrooms/stairs); the model's hallway is a small 2×4 m stub touching only the living room, so the Hallway↔Dining and Hallway↔Kitchen adjacencies are missing, and the front door in truth comes in through an Entry/Foyer at the street end beside the Living Room rather than off the end of a corridor. **Placement.** Correct: the three main rooms in a single front-to-back file, Living on the street side, Kitchen at the deep end, Dining sandwiched between them, hallway alongside on the correct lateral side, balcony door on the kitchen wall away from the hallway (matches the real balcony at the kitchen's right-hand wall). Wrong: the fireplace is drawn on the hallway-side wall of the living room, whereas in truth it sits on the far side wall (opposite the hallway); the living room window is put on that far wall instead. The hallway also doesn't extend alongside dining/kitchen. **Proportions.** Overall footprint 7 m wide × 13 m deep versus the true 7.6 × ~13.4 m for the visited part — very close. Living 5.0×5.0 (true ~5.9×4.3, L-shaped with foyer, so ~6 m deep — acceptable), Dining 5.0×4.0 (true 4.5×3.5 — good), Kitchen 5.0×4.0 (true 4.5×5.3 — kitchen slightly under-deep). The model makes all three rooms the same width, whereas the real Living Room is noticeably wider (it spans across the hallway line), and the hallway is far too short. **Features.** Present and plausibly placed: dining table (with console table), kitchen range and refrigerator along the deep kitchen wall, kitchen table, sofa/two armchairs/coffee table in the living room, balcony/exterior door off the kitchen, front door into the hallway/foyer, living-room window (arched per the description). Misplaced: fireplace on the wrong (hallway-side) wall, and the living-room window on the wall where the fireplace actually is rather than on the street-facing end. No sink/counters in the object list (mentioned only in prose), and no balcony polygon. ## Scores

## Description The video shows a walkthrough of a house floor, starting at the front door. The camera enters a hallway. To the right is the living room, which features a large arched window, a sofa, two armchairs, a coffee table, and a fireplace. The living room connects to a dining room through a wide archway. The dining room has a round table with chairs and a console table. From the dining room, the camera moves into a kitchen. The kitchen has wooden cabinets, a stainless steel range, a refrigerator, a sink, and a small round dining table with chairs. There is a door in the kitchen leading to an exterior balcony or walkway. The camera path goes from the entrance hallway, into the living room, through the dining room, and into the kitchen, ending at the exterior door.

Strengths

• All five visited interior spaces (Foyer/Entry, Hallway, Living, Dining, Kitchen) named correctly with no invented rooms
• Door/opening graph is essentially complete and matches truth, including hallway→dining and hallway→kitchen doors and the foyer archway to the living room
• Camera path Foyer→Hallway→Living→Dining→Kitchen→Balcony is walkable in the model's plan
• Hallway correctly drawn as a long corridor running alongside the main rooms and continuing past them
• Depth chain foyer → dining room → kitchen, with the balcony door on the kitchen's outer side wall, matches truth
• Good object inventory: dining table, range, fridge, sink, dishwasher, sideboard, sofa/chairs/coffee table, arched living-room window noted

Errors

• Living Room placed as a side wing off the foyer instead of being the street-front room with the Dining Room directly behind it
• Dining Room placed behind the foyer rather than behind the living room, so living/dining are side-by-side
• Fireplace put on the living room's interior wall shared with foyer/dining instead of the far exterior side wall; arched window and fireplace effectively swapped walls
• Balcony not drawn as a room (only an exterior door)
• Footprint proportions wrong: 12×12 m square instead of ~7.6×14.1 m deep and narrow; foyer and living-room depth much too large; kitchen aspect ratio inverted
• Plan is a mirror image of the true layout

## Reasoning **Orientation.** The model's plan has the front door at the top of the page, with the Hallway running down the left side. Ground truth has the front door/Entry at the bottom, with the hallway running up the left side. Flipping the model's plan front-to-back (y-flip) puts the entry at the bottom but leaves the hallway on the left — so relative to the truth the plan is **mirrored** (a front-back mirror / equivalently a 180° rotation plus a left-right flip). Handedness is reversed, which I don't penalise per se, but I note it. **Room inventory.** Model rooms: Foyer/Entry, Living room, Dining room, Kitchen, Hallway. Truth visited: Foyer, Hallway, Living Room, Dining Room, Kitchen, Balcony. Every visited interior room is present with the correct name, no invented rooms; only the Balcony is missing as a polygon (though it is described in prose and represented by a kitchen exterior door on the correct wall). **Topology.** Model openings: foyer→exterior (front door), foyer→living (archway), foyer→dining (door), foyer→hallway (door), dining→living, dining→hallway, dining→kitchen, kitchen→hallway, kitchen→exterior (balcony). Ground truth adjacency/doors: Foyer(Living)↔Entry, Foyer↔Hallway, Foyer/Living↔Dining, Living↔Dining, Hallway↔Dining, Hallway↔Kitchen, Kitchen↔Dining, Kitchen↔Balcony. This is essentially a complete match — including the somewhat subtle hallway↔kitchen and hallway↔dining doors, and the balcony door on the kitchen's far-side wall. The camera path Foyer → Hallway → Living → Dining → Kitchen → Balcony traverses the model's graph exactly as in the video. **Placement.** Correct: hallway is a long corridor alongside the main rooms and continues past them; the depth chain foyer → dining → kitchen matches truth (dining behind, kitchen behind dining); kitchen's exterior/balcony door is on the side wall away from the hallway, as in truth. Wrong: in truth the Living Room is the street-front room spanning nearly the whole width, with the Foyer tucked into its left-front corner and the Dining Room directly *behind* the living room. The model instead makes the Living Room a side wing to the right of the Foyer and puts the Dining Room *behind the Foyer*, so living and dining end up side-by-side rather than front/back; the kitchen sits diagonally rather than behind the living/dining stack. The living/dining pair has effectively been rotated 90° about the foyer. **Proportions.** Model footprint 12 m × 12 m versus truth ~7.6 m × 14.1 m: far too wide and not deep enough, so the plan reads as square rather than a deep narrow row-house floor. Living room 6×6 (truth 5.9×4.3 — depth inflated), dining 4×5 (truth 4.5×3.5), kitchen 6×4 (truth 4.5×5.3 — aspect swapped, made wider than deep), foyer 4×3 (truth ~2.7×1.7, much too big), hallway 2×10 (truth ~3 m × 13.5 m in the crop, reasonable). Rank ordering of sizes (living largest, kitchen next, dining, foyer) is right. **Features.** Present and correct: dining table (+ sideboard), kitchen range, fridge, sink counter, dishwasher, breakfast table, balcony/exterior door off the kitchen's far wall, front door into the foyer, arched living-room window (described explicitly, drawn on the living room's exterior wall), living-room fireplace. Wrong: the fireplace is placed on the living room's *interior* wall shared with foyer/dining, whereas in truth it is on the living room's far exterior side wall; the arched window is put on that same far exterior wall, so fireplace and window are essentially swapped relative to truth. The Balcony itself isn't drawn as a room. ## Scores

## Description The floor is roughly rectangular, about 12 m wide by 12 m deep, organised around a small entry foyer at the front with the main rooms branching off it and a service hallway running down the left side. **Foyer / Entry** (top‑centre): entered through a white front door with a diamond‑shaped glazed panel (and an outer decorative wrought‑iron sunburst security gate). To the right an arched opening leads into the living room; straight ahead a wide cased opening with dark‑wood double doors leads into the dining room; to the left a doorway opens onto the long hallway. A wood‑framed full‑length mirror/glass door is on the left wall. **Living room** (right side): a bright room with a large semicircular‑top (arched) window on the exterior right wall, a tiled fireplace with a wood mantel and built‑in wood cabinets on the left wall (shared with the dining room), a pale sofa with fur throws against the right wall under a large abstract painting and a floor lamp, two rounded accent chairs by the arched window, a dark coffee table on a rug, and potted plants (orchid, monstera). It connects to the foyer through the arch and to the dining room through dark‑wood double doors. **Dining room** (centre): an oval/round dining table with upholstered chairs under a brass sputnik chandelier, a console/sideboard with a plant and a gold‑leaf painting, and a window. It opens to the foyer (double doors), to the living room (double doors), to the hallway (left), and via a doorway to the kitchen. **Kitchen** (bottom‑centre/left): wood cabinets with granite counters in an L/U shape, a stainless steel range with hood, a stainless fridge, a sink under a window, a dishwasher, and a small round breakfast table with chairs and sunflowers. A door on the far side leads out to a narrow exterior balcony/side walkway with grey siding and a railing. **Hallway** (left side): a long corridor with several closed doors (bedrooms/bath not entered) and flush ceiling lights; it links the foyer, dining room and kitchen. **Camera path:** starts at the front door/foyer, looks into dining then living, moves into the living room and studies the fireplace and arched window, returns to the foyer and looks down the hallway, re‑enters the dining room, then goes through into the kitchen and finally out the kitchen door onto the exterior balcony. **Uncertainties:** exact room dimensions and the number/destination of the hallway doors are estimated; the precise position of the dining‑room window and of the kitchen sink run is approximate.

Strengths

• All five visited spaces (Entry foyer, Living room, Dining room, Kitchen, Hallway) present with correct names and no invented rooms
• Correct front-to-back chain: Entry/Living on the street side, Dining behind the Living Room, Kitchen at the back
• Long hallway correctly placed alongside the main rooms, entered by a door off the foyer and opening into the kitchen
• Foyer-to-living connection correctly identified as a wide archway; kitchen exterior door to the balcony/light-well captured
• Total depth (14 m) matches the real ~14.1 m; rich and accurate object list (range, fridge, sink, cabinets, dining table, sofa, arched window, fireplace)

Errors

• No Living Room <-> Dining Room opening, which is the main wide connection in reality; dining instead hung off the foyer (a non-existent adjacency)
• Hallway <-> Dining Room adjacency missing; a ~3 x 7 m unassigned void sits between hallway and dining/living block
• Overall width 12 m vs actual 7.6 m; Kitchen aspect transposed (9 x 4 m band instead of 4.5 x 5.3 m) and spanning the full rear width
• Fireplace placed on the living room wall shared with the foyer rather than on the far side wall
• Balcony not modelled as a room and its door put on the kitchen's rear wall instead of the side wall
• Plan is mirrored relative to the truth (hallway on the wrong side going inward)

## Reasoning **Orientation.** The model puts the street/front at the top of its render (y=0 at top, depth increasing downward), whereas Zillow's crop puts the Entry/Living Room at the bottom. More importantly, handedness: in the ground truth, walking from the Foyer into the depth of the flat, the long Hallway is on your **left** and Dining/Kitchen on your right. In the model's plan, walking into the depth (downward), the Hallway is on your **right**. So the plan is **mirrored** (a vertical flip) relative to the truth, plus the 180° front/back page orientation. That is permitted, but noted. **Room inventory.** Model has Entry foyer, Living room, Dining room, Kitchen, Hallway — exactly the five visited spaces, correctly named, nothing invented. The Balcony is not drawn as a room, only as a "service door to exterior light-well/balcony" in the kitchen wall, so the last stop of the camera path is only implicit. **Topology.** The essential chain is right: front door → Entry foyer; foyer → Living room through a **wide archway** (GT: archway from Foyer into Living Room ✓); foyer → Hallway through a door ✓; Hallway runs back alongside and opens into the Kitchen ✓; Dining room → Kitchen door ✓; Kitchen → exterior balcony door ✓. Two errors: (a) the model has **no Living↔Dining opening**, which in the truth is the main wide connection (living room front, dining directly behind through an opening); it instead routes Dining off the Foyer (entry→dining "double doors"), a connection that does not exist (in GT the Dining Room touches the Hallway, not the Foyer). (b) Hallway↔Dining adjacency is missing entirely, because of a geometric gap. Still, the camera sequence Foyer→Hallway→Living→(back through foyer)→Dining→Kitchen→balcony is traversable on the model's plan. **Placement.** Front-to-back ordering is correct: Entry/Living on the street side, Dining behind the Living Room, Kitchen at the back, Hallway running along one long side next to the Dining/Kitchen block and reaching the Kitchen. That is the main structural insight and it is right. Weaknesses: a large unassigned blank void (~3 × 7 m) between the Hallway and the Dining Room where the truth has the hallway/dining wall directly abutting; the Kitchen is stretched across the whole width at the back rather than sitting to the right of a hallway that continues past it; the balcony door is put on the Kitchen's far (back) wall instead of its right-hand side wall; the fireplace is placed on the Living Room wall shared with the Foyer rather than on the far side wall. **Proportions.** Total depth 14 m matches the truth's ~14.1 m nicely, but the width is 12 m vs the actual 7.6 m — over 50 % too wide, largely due to the void. Living room 6.0 × 6.0 vs 5.9 × 4.3 (depth inflated); Dining 6.0 × 4.0 vs 4.5 × 3.5 (roughly OK, a bit big); Kitchen 9.0 × 4.0 vs 4.5 × 5.3 — the aspect is transposed/wrong, it becomes a wide shallow band; Hallway 3.0 m wide × 9 m matches the truth's ~3.0 × 13.5 band reasonably (and cropping the hallway is not penalised). **Features.** Present and correct: front door into the foyer, archway foyer→living, fireplace in the living room (wrong wall), arched living-room window (noted in text and as a window opening, though on the side wall rather than the street wall), dining table with chairs and sideboard, kitchen range, refrigerator, sink, cabinets/counters, breakfast table, exterior kitchen door to the balcony/light-well. Missing: the balcony as a space, and the fireplace/far-wall relationship. ## Scores

## Description The floor is a single level, roughly 12 m (east-west) by 14 m (north-south) in a rectangular footprint. The front (south) side is at y=0. A small square entry foyer (approx 3x3 m) is centered on the front wall behind a white diamond-window door and an arched security gate. The foyer opens east through a wide arched opening into a large living room (approx 6x6 m) that occupies the southeast corner, west through a doorway into a long north-south hallway that runs the entire west side, and north through double dark-wood doors into a dining room (approx 6x4 m) centered on the east side behind the living room. The dining room opens north into a kitchen (approx 9x4 m) that occupies the full north end. The hallway connects the entry to the kitchen's west side and to rear rooms. Exterior walls: front door/gate on the south wall of the entry, a large arched window on the east wall of the living room, a window on the east wall of the dining room, two windows on the east wall of the kitchen, and a service door on the north wall of the kitchen to a narrow exterior light-well/balcony. Interior doors are dark wood, ~0.9 m wide; the living archway is ~1.4 m wide. Significant objects: Living room - white sofa against east wall, dark wood coffee table center, two beige swivel armchairs by the arched window, tiled fireplace with wood mantel on the west wall, floor lamp, large potted plants, wall art above sofa. Dining room - round table with 5-6 light chairs center, sputnik chandelier above, dark console against north wall, large gold abstract paintings. Kitchen - U-shaped medium oak cabinets with granite counters, stainless gas range centered on north wall, refrigerator on west wall, sink under east windows, small round breakfast table with 4 white chairs in the southeast corner of the kitchen, dishwasher. Hallway - wood parquet throughout living/dining/hall, tile in kitchen and entry. Camera path: starts outside the front gate looking in, enters the foyer, pans to show the hallway and the dining double doors and the living archway, moves into the living room and pans along the sofa wall to the arched window and fireplace, returns to the foyer, looks down the west hallway, moves through the dining room, then through the north door into the kitchen, pans the kitchen counters and breakfast nook, exits the north service door to the exterior light-well, then returns inside. Uncertain: exact north-south depth of kitchen and hallway, exact position of dining east window, and whether the hallway continues beyond the kitchen; dimensions are approximate and walls are assumed orthogonal.

Strengths

• All visited interior rooms present and correctly named (Foyer, Living, Dining, Kitchen, Hallway) plus the real hallway bathroom, with no invented rooms
• Connectivity is almost complete and the full camera path Foyer→Hallway→Living→Dining→Kitchen→Balcony is walkable on the plan
• Hallway correctly modelled as a long strip running alongside the main rooms off the foyer
• Balcony door correctly on the kitchen's outer (non-hallway) wall; front door into the foyer
• Rich, accurate feature/object list: fireplace, arched windows, dining table, range, fridge, dishwasher, breakfast table

Errors

• Plan is mirrored relative to the truth (hallway on the wrong flank)
• Kitchen placed lateral to the Dining Room instead of behind it, breaking the Living→Dining→Kitchen front-to-back spine and losing the hallway–kitchen adjacency
• Global footprint wrong shape: ~11 m wide × 9 m deep instead of ~7.6 m wide × 14 m deep
• Hallway drawn 3 m wide (truth ~0.9 m) and foyer squared off at 3 × 3 m
• Fireplace put on the living room wall shared with the foyer rather than on the far side wall; arched window on the wrong wall
• Balcony omitted as a room even though the camera stepped onto it

## Reasoning **Orientation / chirality.** In the truth, with "deeper into the flat" pointing up the page, the Living Room sits at the street end, the Foyer is beside it on the *left*, the Hallway runs up the *left* edge, the Dining Room is directly behind (deeper than) the Living Room, and the Kitchen is behind the Dining Room; the Balcony and the fireplace are both on the *right* (non-hallway) side. In the model's plan, depth runs downward (Living room at top, Dining below it), so normalising by rotating 180° puts the Hallway/Foyer on the **right** of the depth axis — i.e. the model's plan is **mirrored** (with a ~90–180° rotation of the drawing) relative to the truth. And even after mirroring, the Kitchen ends up *beside* the Dining Room instead of behind it. **Room inventory.** Entry foyer, Living room, Dining room, Kitchen, Hallway, Bathroom — all real and all visited or legitimately glimpsed (the hallway bathroom does exist in the truth, 1.6 × 3.4 m off the hallway). No invented rooms. The **Balcony**, which the camera actually stepped onto, is not drawn as a room, only as a "kitchen → exterior" door (it is described in prose). Entry is folded into the foyer, which is acceptable. **Topology.** Very good. Front door → Foyer ✓; Foyer → Living room via archway ✓ (truth: Foyer archway into Living Room); Foyer → Hallway ✓; Living → Dining archway ✓; Dining → Kitchen ✓; Kitchen → exterior balcony door ✓; Hallway → Dining door ✓ (truth has hallway/dining shared wall); Hallway → Bathroom ✓. The whole camera path Foyer → Hallway → Living → Dining → Kitchen → Balcony is traversable on the model's plan. Only missing relationship: the Hallway also runs alongside the **Kitchen** in truth, which is impossible in the model because the kitchen was pushed sideways. **Placement.** Correct: foyer beside living room, hallway as a long strip alongside the main rooms on one flank, dining behind the living room, balcony off the kitchen's outer (non-hallway) wall, front door on the street flank. Wrong: the kitchen is lateral to the dining room rather than the next room back, so the linear front-to-back spine Living→Dining→Kitchen is broken; the plan is mirrored; and the fireplace is put on the living room wall shared with the foyer rather than on the far side wall (truth: right-hand end wall, opposite the foyer). The arched window is placed on the wall away from the foyer rather than on the street-facing long wall. **Proportions.** Individual rooms are decent (Living 6.0 × 5.0 vs 5.9 × 4.3; Dining 4.0 × 4.0 vs 4.5 × 3.5; Kitchen 4.0 × 4.0 vs 4.5 × 5.3). But the global footprint is badly off: the model says ~11 m wide × 9 m deep, a squat rectangle, whereas the visited part is 7.6 m wide × 14.1 m deep with the hallway continuing further. The hallway is drawn 3 m wide (truth ~0.9 m), and the foyer is 3 × 3 instead of ~2.7 × 1.7. **Features.** Fireplace present (wrong wall), arched living-room windows noted, dining table + console + chandelier, kitchen range, fridge, dishwasher, counters, breakfast table, balcony door on the kitchen's right wall (correct side), front screen/panel door into the foyer. Good feature recall, with the fireplace wall being the main geometric error. ## Scores

## Description The floor is a roughly rectangular, single‑storey apartment (about 11 m wide by 9 m deep) organised around a central **entry foyer** at the top‑left. The front door is a white paneled door with diamond glass inserts and a decorative blue‑topped metal screen/grille door; it opens onto the foyer. From the foyer three ways lead: an **archway to the living room** on the right, an **open passage down a long hallway** on the left, and a **doorway into the dining room** in the centre. The **living room** (right side, ~6 m × 5 m) is the largest room. Its right wall is dominated by two large arched windows looking out to the exterior; it contains a long light‑coloured sofa against the right wall, two or three swivel lounge chairs by the windows, a low dark coffee table in the centre, a floor lamp, potted plants, and a tiled **fireplace** with a wood mantel on the wall shared with the dining room. A large framed artwork hangs above the sofa. The **dining room** (centre, ~4 m × 4 m) holds a round dining table with upholstered chairs under a modern chandelier, a dark console table with art and a plant along one wall, and windows on the far wall. It connects to the living room (open archway), to the hallway (door), and to the **kitchen** (door). The **kitchen** (right‑centre, ~4 m × 4 m) has warm wood cabinetry, granite counters, a stainless steel range with hood on the back wall, a tall fridge on the left, a dishwasher, a sink, several windows, and a small round breakfast table with chairs. A door on its right wall leads out to a covered exterior **balcony/walkway** with railings and grey siding. The **hallway** (left column, ~3 m × 6 m) runs from the foyer to the back; it has a wood‑framed glass door opening to a small **bathroom** (mirror and tile visible through the glass) and several closed doors leading to bedrooms that were *not* entered in this walkthrough (so they are not drawn as rooms). Camera path: started at the front screen door, panned across the foyer into the living room, looked back down the hallway, returned through the dining room, entered the kitchen, and finally stepped out onto the exterior balcony. Uncertainties: exact bedroom count/positions (doors seen but rooms not entered), precise bathroom footprint, and exact window placements are inferred.

Strengths

• All visited rooms present and correctly named (Foyer, Living, Dining, Kitchen, Hallway, outdoor deck/balcony) with no invented rooms
• Connectivity is essentially correct and supports the camera path: front door→Foyer, Foyer→Hallway, Foyer→Living (arch), Living↔Dining (wide opening), Dining→Kitchen, Kitchen→Deck
• Arrangement is internally consistent with the truth under a diagonal mirror: Living–Dining–Kitchen chain with hallway alongside, kitchen at the rear, balcony off the kitchen exterior wall
• Rich, accurate feature set: fireplace with mantel/built-ins, arched window, dining table+chandelier, range/hood, fridge, sink under window, counters, breakfast nook, balcony door

Errors

• Plan is a diagonal reflection, so Living and Dining are transposed relative to the Foyer (Living should be on the street side in front of the Dining Room, not beside it)
• Fireplace placed on the Living Room wall nearest the Foyer/Dining instead of on the far end wall
• Arched window put on the Living Room's far short wall rather than the street-facing long wall
• Hallway drawn as a wide, almost square room (3.5×5.5 m) instead of a ~1 m corridor running deep past the kitchen
• Foyer greatly oversized (4×3 m vs 2.7×1.7 m); Kitchen undersized in depth
• Balcony/deck on the kitchen wall facing the hallway side rather than the wall consistent with GT; Entry/front-door side shifted 90°

## Reasoning **Global orientation.** The model's plan is not a simple rotation or mirror — it corresponds to the ground truth reflected about a *diagonal* (i.e. mirrored **and** rotated 90°). Test: reflect GT coordinates about y=x. GT Foyer (front-left) → becomes centre with Living Room to its east and Dining Room "below" it, Hallway running west from it. That is exactly the model's arrangement (Foyer centre-north, Living Room east, Dining Room south of Foyer, Hallway west, Kitchen at the far south-west, Deck off the kitchen's outer wall). Since a diagonal reflection is a permitted mirror+rotation, the arrangement is largely internally consistent with GT; the residual errors are local (fireplace/window walls, balcony wall, hallway width). **Room inventory.** Foyer, Living Room, Dining Room, Kitchen, Hallway and the outdoor space are all present and correctly named ("Deck", described as the narrow balcony off the kitchen — acceptable). Nothing invented (the "breakfast nook" is a piece of kitchen furniture, matching the kitchen's small table area). Bedrooms/baths off the hallway are correctly left unexplored/undrawn. **Topology.** Very good, and it matches the camera path Foyer → Hallway → Living → Dining → Kitchen → Balcony: - Front door → Foyer ✓ (GT: Entry → Foyer) - Foyer ↔ Hallway door ✓ (GT: door from foyer into long hallway) - Foyer ↔ Living Room arched opening ✓ (GT archway) - Living ↔ Dining wide column-framed opening ✓ (GT Living↔Dining) - Foyer/Dining opening ✓ (GT PNG shows an opening in the Foyer–Dining wall) - Dining ↔ Kitchen ✓ (GT Kitchen↔Dining) - Kitchen ↔ Deck door ✓ (GT Kitchen↔Balcony) - Hallway also borders Kitchen (model's "hall end door") ✓ (GT Hallway↔Kitchen) Only small omissions: no explicit Hallway↔Dining door, and the front door is placed on the Foyer's "north" wall rather than the side wall from the Entry. **Placement.** Under the diagonal mirror, the chain Living → Dining → Kitchen with the hallway running alongside is reproduced, the Living Room touches the street-facing exterior wall, and the outdoor deck hangs off the Kitchen's exterior wall opposite the hallway. Deviations: the Kitchen is shifted to the hallway side rather than staying aligned with the Dining Room's outer wall (GT Kitchen and Dining share the same right-hand edge); the Deck is on the kitchen's west wall where the consistent mapping would place it on the kitchen's far south wall; the Foyer is drawn as a large central room rather than a small vestibule tucked beside the Living Room. **Proportions.** Model states 12 × 9 m; the transposed visited footprint is ~14.1 × 7.6 m — the right general aspect for the mirrored frame but squarer than truth. Living Room 4.5×6 vs GT 5.9×4.3 (transposed 4.3×5.9) ✓ good. Dining 4×4 vs 3.5×4.5 ✓ fine. Kitchen 4.5×3.5 vs 4.5×5.3 — undersized. Foyer 4×3 m vs GT 2.7×1.7 m — much too big. The biggest shape error is the Hallway drawn as a 3.5 m-wide near-square room rather than a ~1 m-wide corridor continuing deep into the plan. **Features.** Fireplace present in the Living Room but on the wall shared with the Foyer/Dining, whereas GT has it on the far short end wall opposite the foyer end — right wall type, wrong end. Arched window present but placed on the Living Room's far short wall rather than the street-facing long wall (GT window in the bottom exterior wall). Dining table + chandelier ✓, kitchen range with hood, fridge, sink under window, dishwasher, L-shaped granite counters ✓, breakfast nook ✓, kitchen-to-deck door ✓, front door with iron security door into foyer ✓.

## Description The floor is roughly rectangular, about **12 m wide (E–W) by 9 m deep (N–S)**, with the main entrance on the north (top) side. The camera enters through a decorative wrought‑iron‑and‑glass security door and a white front door with a diamond window into a small **Foyer** with herringbone parquet. From the foyer the plan opens three ways: east through an arched opening into the **Living Room**, south through a wide cased opening (dark‑wood double doors) into the **Dining Room**, and west into a long **Hallway** that runs toward the rear with several white doors (bedrooms/bath – not entered). The Living and Dining rooms also communicate through a wide column‑framed opening. The Dining Room connects south‑west into the **Kitchen**, and the Kitchen has a door on its west wall onto a narrow exterior **deck/balcony** (gray siding, railing) – the only outdoor space seen. **Foyer (front‑center):** parquet floor, front door on the north wall, a mirrored/glass wood door on the west side, openings to living (E), dining (S) and hallway (W). **Living Room (east):** a tiled **fireplace** with wood mantel, decorative tiles and flanking built‑in wood cabinets with lattice doors on the west wall; framed art and two sconces above; arched wall niches. A large **arched window** dominates the east wall. A white **sofa** with a big abstract canvas above it sits along the south wall with a **floor lamp**; two swivel **accent chairs** and a low dark **coffee table** with an orchid sit in the center; potted plants near the fireplace. **Dining Room (center):** oval table with white chairs under a sputnik **chandelier**; gold abstract art and a console table with a plant on the east wall; windows on the north wall; doorways to foyer (N), living (E), kitchen (SW) and hallway (W). **Kitchen (south‑west):** wood cabinets with granite counters along the west and south walls, stainless **range** with hood, stainless **fridge**, **sink** under a window, **dishwasher**; a small round **breakfast table** with white chairs and sunflowers by the east windows; a door on the west wall to the deck. **Hallway (west):** long corridor with ceiling lights and multiple white doors (rooms not explored). **Camera path:** front door → foyer → look into dining & living → living room pan (sofa, art, fireplace) → back to foyer/hallway glance → dining room → kitchen → breakfast nook → out the deck door and back. **Uncertainties:** exact room dimensions and the contents/terminus of the rear hallway are not fully observable; the living/dining opening and the foyer arches are inferred from sight‑lines. The exterior deck is shown for context but is not interior floor area. ## Objects ```json [ {"name": "floor", "x": 0, "y": 0, "w": 12, "h": 9, "rotation_deg": 0, "confidence": "medium", "notes":

Strengths

• All six visited spaces (Foyer, Main Hallway, Living Room, Dining Room, Kitchen, Balcony) present, correctly named, with unseen areas left blank rather than invented
• Connectivity graph matches the truth: Foyer/hall→Living via arch, Living→Dining, Hall→Dining, Dining→Kitchen, Hall→Kitchen, Kitchen→Balcony; the camera path walks cleanly
• Hallway correctly modelled as a circulation spine running alongside the main rooms with the front door at its end
• Rich, correctly assigned feature set: fireplace with mantel, arched living-room window, dining table + chandelier, range/fridge/sink/counters, balcony door, glazed front door

Errors

• Footprint wrong shape: ~14 m × 12 m (near-square) instead of ~7.6 m wide × 14 m deep
• Living Room grossly oversized (~60 m² vs 25 m²) while the Kitchen is drawn as a shallow strip instead of the second-largest room
• Balcony placed on the hallway side (east) of the kitchen rather than on the kitchen's far exterior wall
• Kitchen offset to the hallway side instead of sitting squarely behind the Dining Room
• Fireplace put on the Living Room end wall and arched window on the side wall (reflected from the truth, where the arched window faces the street and the fireplace is on the far side wall)
• Front door placed in a side exterior wall of the hallway rather than at the street end of the Foyer/Entry

## Reading the model's plan against the ground truth **Global orientation.** In the truth (image A/B, y down) the street-facing Entry/Foyer + Living Room are at the bottom, the Dining Room sits behind the Living Room, the Kitchen behind the Dining Room, and the Hallway runs up the *left* side alongside Dining/Kitchen to the bedrooms. The model draws the Foyer at the top-right, the Living Room top-left, the Dining Room in the middle, the Kitchen at the bottom, and the "Main Hallway" as a vertical spine on the *right*. That is essentially the truth rotated ~180° (walking Living → Dining → Kitchen, the hallway is still on the walker's left, so handedness is preserved — it is a rotation, not a mirror). The one element that breaks the consistency is the balcony: in the truth it hangs off the Kitchen wall *opposite* the hallway; the model puts the "Side Balcony" east of the kitchen, i.e. on the *same* side as the hallway spine. **Inventory.** Living Room, Dining Room, Kitchen, Foyer, Main Hallway, Side Balcony — exactly the visited set, correctly named, and the unseen west/south area is left blank/unlabelled rather than invented as named rooms. Minor: "Side Balcony" instead of just Balcony; no separate Entry stoop (folded into the front door). **Topology (heaviest weight).** Every ground-truth adjacency the camera used is present: front door → Foyer (north end of hallway); Foyer/Hallway → Living Room via an *arched* opening; Living Room → Dining Room via a doorway in its south wall; Hallway → Dining Room; Dining Room → Kitchen; Hallway → Kitchen; Kitchen → Balcony via a door. The camera sequence Foyer → Hallway → Living → Dining → Kitchen → Balcony can be walked on this plan without contradiction. This is a genuinely correct connectivity graph. Small deviation: the front door is placed on the hallway's side (east) exterior wall rather than at the end of the hall facing the street, and in the truth the Living Room adjoins the hallway mainly through the Foyer rather than along a long shared wall. **Placement.** Correct: hallway as a spine running alongside the main rooms; Foyer at the hallway's end next to the Living Room; Dining Room between Living Room and Kitchen; Kitchen at the far end from the entrance. Errors: the Kitchen is shifted to the hallway side and shortened so it no longer lines up behind the Dining Room across the full width; the balcony is on the hallway side of the kitchen instead of the far exterior wall; the fireplace/window pair in the Living Room is reflected (window on the long side wall, fireplace on the end wall) relative to the truth (arched window on the street wall, fireplace on the far side wall) — though they are correctly perpendicular to each other. **Proportions.** The stated footprint is 14 m × 12 m (nearly square) versus the real 7.6 m wide × 14 m deep — the plan is far too wide and not deep enough; the drawing is a square. The Living Room is drawn ~10 × 6 m (60 m²) when it is 5.9 × 4.3 m (~25 m²), while the Kitchen (really the second-largest room at 4.5 × 5.3 m) is drawn as a shallow 5 × 3 m strip. Dining Room (5 × 3 vs 4.5 × 3.5) is the one reasonable room. The hallway's width relative to rooms is plausible. **Features.** Present and correctly attributed: tiled fireplace with mantel in the Living Room (on an exterior wall, though the wrong one), large arched multi-pane window in the Living Room, round dining table with chairs and chandelier, kitchen range, refrigerator, sink under windows, counters/cabinets, balcony door off the kitchen, front door with glass panes into the foyer, mirrored hall closet. Missing/misplaced: the balcony is on the wrong wall, and the extra "breakfast table" in the kitchen and kitchen "west-wall range" placement are approximate.

## Description This floor of the house has a roughly rectangular footprint, approximately 14 meters wide (east-west) and 12 meters deep (north-south), with the main front entrance on the east exterior wall. The layout includes five main interior spaces (foyer/entry, living room, dining room, main hallway, kitchen) plus an exterior side balcony, with additional unseen rooms accessible off the main hallway and west of the dining/living area. ### Room Connections & Layout - **Main Hallway**: A long north-south corridor running along the east side of the floor, acting as the main circulation spine. The front entry door is set into the east wall of the hallway near its north end. - **Foyer**: The entry area of the main hallway, immediately inside the front door. It provides access to the living room (via an arched opening on the west wall, north side) and the dining room (via a rectangular doorway on the west wall, south of the living arch). A full-length mirrored closet is set into the west wall of the hallway, north of the living room arch. The north end of the hallway terminates at a white interior/utility door with diamond glass detailing matching the front door. - **Living Room**: A large corner room occupying the northwest portion of the floor, west of the main hallway's north section. It has two exterior walls: the north wall features a tiled fireplace with a wood mantel, and the west wall has a large arched multi-pane window. It connects to the main hallway via an archway in its east wall, and directly to the dining room via a rectangular doorway in the southeast portion of its south wall. - **Dining Room**: A central room south of the living room's east section, west of the main hallway's mid-section. It connects to the main hallway (east wall), living room (north wall, east side), and kitchen (south wall, east side). A sliding exterior window is set into its south wall, west of the kitchen doorway. - **Kitchen**: A corner room in the southeast portion of the floor, south of the dining room and east of the main hallway's south end. It has two exterior walls: the south wall has two large windows above the sink and counter, and the east wall has a door leading out to the side balcony. It connects directly to both the dining room (north wall, west side) and the main hallway (north wall, east side). - **Side Balcony**: A narrow exterior deck east of the kitchen, between the house and a neighboring building. It has a horizontal metal railing, gray siding on adjacent building walls, and stairs leading down to a lower level. ### Key Objects by Room - **Foyer/Hallway**: White front door with diamond-shaped glass inserts (exterior side has a decorative metal security gate), mirrored closet door with dark wood frame, recessed ceiling lights, framed wall art, multiple dark wood interior doors leading to unseen rooms, white diamond-glass door at the north end of the hall. - **Living Room**: White sofa with decorative pillows (against the south wall, east side), large textured abstract wall art above the sofa with a wall sconce light, black rectangular coffee table (center of the room), two brown swivel armchairs with white cushions (facing east, in front of the west window), brass floor lamp with white shade (next to the fireplace on the north wall), tiled fireplace with decorative tile inlays and wood mantel, framed black-and-white art above the fireplace mantel with a small potted succulent, multiple potted plants (large leafy plant in a white pot near the fireplace east side, white orchid arrangement on the coffee table, additional greenery near the window). - **Dining Room**: Round dining table with a light neutral tablecloth, six light gray upholstered dining chairs, modern brass chandelier with multiple bulbs (hanging above the table), dark wood console table (against the west wall), large gold-and-white abstract painting above the console table, smaller framed gold-patterned art on the north wall, tall green potted plant on the console table, sliding exterior window on the south wall. - **Kitchen**: Light brown wooden upper and lower cabinets with speckled gray granite countertops, stainless steel gas range/oven (set into the west wall), stainless steel refrigerator (northwest corner, near the dining room doorway), stainless steel sink under the south-facing windows, stainless steel dishwasher (east wall near the balcony door), small round light wood breakfast table with white-seated chairs (near the east balcony door), vase of sunflowers on the breakfast table, bowl of green apples on the south counter, potted white flowers by the sink, various kitchen decor (bottles, canisters, cookbooks). - **Side Balcony**: Gray metal horizontal railing, exterior gray house siding, wall-mounted coat hooks near the kitchen door, stairs descending to a lower level. ### Camera Path The camera starts at the front door, looking out east at the exterior security gate. It turns west to face into the house, showing the arched opening to the living room (right/north) and doorway to the dining room (left/south) on the west wall of the entry hall. It then moves west through the arch into the living room, pans around to show the fireplace, window, sofa, and furniture, then exits back east to the hallway. The camera moves south down the hallway, pauses to look into the dining room, then enters the dining room and pans around to show the table, console, and window. It exits south into the kitchen, explores the kitchen showing cabinets, appliances, the breakfast table, and windows, then exits east through the balcony door onto the side balcony, panning around the exterior space before the video ends. ### Uncertainties The full extent of the floor west of the dining room and south of the living room's west section is unknown, as these areas were not entered or fully visible. The exact size and number of unseen rooms off the main hallway are estimated. The position of smaller decorative objects is approximated based on their appearance in the video. ## Objects ```json [ {"name": "floor", "x": 0, "y": 0, "w": 14, "h": 12, "rotation_deg": 0,

Strengths

• All visited rooms named correctly (Kitchen, Dining, Living Room, Foyer, Hall/Bath) with no invented rooms
• Every adjacency along the camera path reproduced: Foyer-Hall, Foyer-Living, Living-Dining, Dining-Kitchen, Kitchen-Balcony, plus the Foyer-Dining opening that Zillow also shows
• Correct handedness: hallway on the west flank of the foyer, living room east of the foyer, street wall with front door and arched window at the front
• Good object detail: arched living-room window on the street wall, dining table + chandelier, range with hood, fridge, counters, balcony door off the kitchen

Errors

• Overall footprint aspect inverted: wide 12x8 m instead of narrow 7.6x14 m deep, so Dining sits beside rather than behind the Living Room and Kitchen beside rather than behind the Dining Room
• Hallway does not run alongside the Kitchen and Dining Room (missing Hallway-Kitchen and Hallway-Dining relations) and is drawn as a stub west of the foyer
• Fireplace placed on the wall shared with the Foyer/Dining instead of the living room's far side wall
• Balcony not drawn as a room and its door put on the kitchen's far (north) wall rather than the side wall
• Kitchen squashed (5x3 m vs 4.5x5.3 m) and the notched front of the living room / separate Entry landing omitted

## Reasoning **Orientation / global transform.** The model keeps the street side at the bottom of its drawing (front door + arched window on the south wall, balcony door on the north wall), so it is not mirrored in the local sense: from the Foyer the Living Room lies east, the Hall west, the front wall south — exactly the GT handedness (GT: Foyer with Living Room to its east, hallway to its west, Entry to the south). However the deep back half of the plan has effectively been *rotated 90°*: in the truth the chain Living → Dining → Kitchen runs **away from the street** (down the 14 m depth), whereas the model lays it out **sideways** (Living Room east, Dining centre, Kitchen north-west), turning a 7.6 × 14 m deep plan into a 12 × 8 m wide one. So: not mirrored, but the interior chain is rotated/compressed relative to the façade. **Room inventory.** Kitchen, Dining, Living Room, Foyer, Hall/Bath are all present and correctly named — the full set of visited rooms except the Balcony, which is not drawn as a room but is represented by a "balcony_door" on the kitchen's outer wall and described as exterior. No invented rooms (the "breakfast table" and powder room are plausible inferences, not fabricated rooms). Very good. **Topology.** Every adjacency along the camera path is present: Foyer↔Hall (door arc drawn), Foyer↔Living Room (opening at the wall segment by the fireplace), Foyer↔Dining (north opening), Dining↔Living Room (door arc at the shared wall), Dining↔Kitchen (open), Kitchen↔Balcony (exterior door). That reproduces GT's Living↔Dining, Dining↔Kitchen, Kitchen↔Balcony, Living/Foyer↔Hallway, and even the Foyer–Dining opening Zillow shows. Missing: the long hallway also runs alongside the Kitchen and Dining Room in the truth (Hallway↔Kitchen, Hallway↔Dining); in the model the hall dead-ends beside the dining room and never borders the kitchen. Also the hall is drawn much shorter than the real corridor to the bedrooms (allowed, but it changes the alongside relationship). **Placement.** Correct: Living Room and Foyer on the street side, hallway on the west flank of the foyer, Dining between Living Room and Kitchen, Kitchen deepest with the balcony on its outer wall. Wrong: Dining is *beside* (west of) the Living Room rather than *behind* it, and the Kitchen is beside the Dining rather than behind it, so the hallway no longer runs alongside the main rooms and the plan's long axis is perpendicular to reality. The balcony is put on the kitchen's far wall rather than its side wall (minor). **Proportions.** Footprint 12 × 8 m vs the true 7.6 × 14.1 m — the aspect ratio is essentially inverted. Individual rooms are not bad: Dining 5 × 3.5 vs 4.5 × 3.5 (good), Living 5 × 5.5 vs 5.9 × 4.3 (roughly right area), Kitchen 5 × 3 vs 4.5 × 5.3 (squashed). The distinctive deep, narrow row-house shape and the notched living-room front are lost. **Features.** Arched window on the living room's street wall ✓, front door into the foyer ✓, dining table with chandelier ✓, kitchen range with hood, refrigerator, counters/peninsula ✓, balcony door off the kitchen ✓. The fireplace is present but placed on the *near* wall between Living Room and Foyer/Dining, whereas in truth it is on the living room's far side wall (opposite the foyer) — a clear misplacement of the single most distinctive living-room feature. ## Scores

## Description This is a single upper floor of a townhouse / row house. The overall footprint is roughly rectangular, about 12 m (east–west) by 8 m (north–south). The front (south) wall holds the main entrance: a white paneled door with a diamond glass insert, set behind a decorative sunburst metal screen door, with a small tiled entry landing. The back (north) wall is the exterior of a narrow open balcony / service walkway (grey clapboard, railing, skylight above) reached through a door off the kitchen. Rooms and connections: - **Entry / Foyer** (south‑center): tiled floor, opens north into the main living space and has a doorway to the west leading to a short **hallway** that runs north with several doors (a bathroom / powder room on the left, a bedroom or study at the far end). - **Living Room** (east of the foyer): large room with a big arched (round‑top) window on the south wall, a tiled fireplace with wood mantel on the west wall, a sofa, two lounge chairs, a coffee table, a floor lamp and a large abstract canvas on the east wall. It connects west to the foyer and northwest to the dining room. - **Dining Room** (west of the living room, north of the foyer): oval dining table with chairs, a chandelier, a console table with art on the north wall, and a window on the east wall. It connects east to the living room, south to the foyer, and north to the kitchen. - **Kitchen** (north‑west): L/U‑shaped wood cabinetry, stainless range with hood, refrigerator, dishwasher, granite counters, a small round breakfast table by the windows, and a door on the north wall opening to the exterior balcony. - **Hallway / Bath** (west): a corridor off the foyer with a bathroom (powder room) and a door at the end. Camera path (for context only): starts at the front door, looks into the living room and dining room, pans across the fireplace and arched window, moves through the dining room into the kitchen, then out to the back balcony, and finally back toward the hallway. Uncertainties: exact room dimensions and the precise function of the hallway doors (bathroom vs. bedroom) are inferred; the balcony is treated as exterior. Wall thicknesses and the exact position of the foyer/hall junction are approximate. ## Objects ```json [ {"name":"floor","x":0,"y":0,"w":12,"h":8,"rotation_deg":0,"confidence":"high","notes":"Overall footprint of the floor"}, {"name":"Entry / Foyer","x":4.5,"y":5.5,"w":3,"h":2.5,"rotation_deg":0,"confidence":"medium","notes":"Tiled landing at front door"}, {"name":"Living Room","x":7,"y":2,"w":5,"h":5.5,"rotation_deg":0,"confidence":"high","notes":"East room with arched window and fireplace"}, {"name":"Dining Room","x":2,"y":2,"w":5,"h":3.5,"rotation_deg":0,"confidence":"high","notes":"Oval table, chandelier"}, {"name":"Kitchen","x":0,"y":0,"w":5,"h":3,"rotation_deg":0,"confidence":"high","notes":"North-west, wood cabinets, range"}, {"name":"Hallway / Bath","x":0,"y":3,"w":2,"h":5,"rotation_deg":0,"confidence":"medium","notes":"Corridor off foyer with bath"}, {"name":"front_door","x":5.6,"y":7.7,"w":1.0,"h":0.2,"rotation_deg":0,"confidence":"high","notes":"Main entrance door + screen"}, {"name":"balcony_door","x":2.4,"y":0.0,"w":1.0,"h":0.2,"rotation_deg":0,"confidence":"medium","notes":"Door to exterior balcony"}, {"name":"arched_window","x":8.5,"y":7.7,"w":2.5,"h":0.2,"rotation_deg":0,"confidence":"high","notes":"Round-top window, living room south wall"}, {"name":"dining_window","x":6.9,"y":3.5,"w":0.2,"h":1.5,"rotation_deg":0,"confidence":"medium","notes":"Window east wall of dining"}, {"name":"kitchen_window","x":4.0,"y":0.0,"w":1.5,"h":0.2,"rotation_deg":0,"confidence":"medium","notes":"Window over sink, north wall"}, {"name":"fireplace","x":7.0,"y":3.5,"w":0.4,"h":2.0,"rotation_deg":0,"confidence":"high","notes":"Tiled fireplace, west wall of living room"}, {"name":"sofa","x":10.5,"y":4.5,"w":1.2,"h":2.5,"rotation_deg":0,"confidence":"high","notes":"Sofa against east wall"}, {"name":"coffee_table","x":9.0,"y":4.5,"w":1.5,"h":1.0,"rotation_deg":0,"confidence":"high","notes":"Low table in living room"}, {"name":"lounge_chairs","x":8.5,"y":6.5,"w":2.0,"h":0.8,"rotation_deg":0,"confidence":"medium","notes":"Two chairs by arched window"}, {"name":"dining_table","x":3.5,"y":3.5,"w":1.8,"h":1.8,"rotation_deg":0,"confidence":"high","notes":"Oval dining table"}, {"name":"console_table","x":3.0,"y":2.0,"w":2.0,"h":0.4,"rotation_deg":0,"confidence":"medium","notes":"Console with art, north wall of dining"}, {"name":"range","x":2.0,"y":0.4,"w":0.9,"h":0.7,"rotation_deg":0,"confidence":"high","notes":"Stainless range + hood"}, {"name":"refrigerator","x":0.4,"y":0.4,"w":0.8,"h":1.0,"rotation_deg":0,"confidence":"high","notes":"Fridge, west wall"}, {"name":"kitchen_island_counter","x":3.5,"y":1.5,"w":1.5,"h":0.8,"rotation_deg":0,"confidence":"medium","notes":"Counter / peninsula"}, {"name":"breakfast_table","x":4.3,"y":2.2,"w":1.0,"h":1.0,"rotation_deg":0,"confidence":"medium","notes":"Round table by kitchen windows"} ] ```

Strengths

• All and only the visited rooms named: Entry, Foyer, Living Room, Dining Room, Kitchen, Hallway, Balcony
• Foyer correctly identified as the distribution point with an arched opening to the Living Room, a doorway to the Dining Room and the Hallway leading off it
• Dining→Kitchen doorway and Kitchen→Balcony door correct; camera path Foyer→Hall→Living→Dining→Kitchen→Balcony is traversable in the drawn plan
• Kitchen correctly the deepest room, farthest from the entry, with Dining between Foyer and Kitchen
• Rich, accurate feature set: fireplace on a Living Room side wall, large arched Living Room window, round dining table/chandelier/console, range+hood, fridge, granite counters, sink under window, balcony door, front door with arched gate

Errors

• Missing the direct wide opening between Living Room and Dining Room (truth has them in line, sharing an opening)
• Hallway drawn as a central corridor between Living and Dining instead of running along the west exterior side past Dining/Kitchen to the bedrooms
• Living Room made a full-depth wing beside Dining/Kitchen rather than the street-front room with Dining behind it
• Arched Living Room window placed on the wall farthest from the street; in truth it is on the street façade next to the Entry
• Balcony placed off the Kitchen's far end wall instead of its right-hand side wall
• Footprint far too wide and nearly square (14 × 12 m vs ~7.6 × 14.1 m); Dining Room greatly oversized and Kitchen's aspect ratio flipped

## Reasoning **Global orientation.** Ground truth (cropped): the street/Entry and Living Room are at the bottom of the page, the Dining Room sits directly behind (above) the Living Room, the Kitchen behind the Dining Room, and the long Hallway runs up the **left (west) side** past the small bathroom/stairs to the bedrooms. Balcony hangs off the Kitchen's right-hand wall. The model puts the street/Entry at the **top** (so the depth axis is flipped, roughly a 180° rotation of the front direction), but it also **rearranges** the rooms: the Living Room becomes a full-depth column on the east side, while Dining + Kitchen form a parallel column on the west, with the Hallway squeezed **between** them. So this is not a clean rotation or mirror of the truth — it is a structural re-plan (the truth's linear front-to-back Living→Dining→Kitchen chain is replaced by two side-by-side columns). **Room inventory.** Foyer, Entry/front door, Living Room, Dining Room, Kitchen, Hallway and Balcony are all present and correctly named — exactly the visited set. No invented rooms (the "breakfast" table and "lightwell" are just furniture/description within the Kitchen and Balcony). Very good. **Topology.** Correct connections: Entry → Foyer (front door), Foyer → Living Room via **arch** (truth: archway from foyer to living room), Foyer → Hallway, Foyer → Dining Room (an opening does exist there in the Zillow PNG), Dining → Kitchen, Kitchen → Balcony, Hall → Dining and Hall → Kitchen. The camera sequence Foyer → Hall → Living → (back through foyer/hall) → Dining → Kitchen → Balcony is traversable in the model's plan. Misses: the **direct wide opening between Living Room and Dining Room** is absent (the model interposes the Hall), and the Hallway is placed as a central corridor between Living and Dining rather than running along the outer (west) side alongside Dining/Kitchen, which is the key spine of this apartment. **Placement.** Partially right: the Kitchen is the deepest room, farthest from the entry, with the Dining Room between Foyer and Kitchen — that ordering matches the truth's Foyer→Dining→Kitchen progression. The Living Room adjoins the Foyer, also correct. But the Living Room should be the *street-front* room with the Dining Room directly behind it, not a parallel full-depth wing; consequently the arched window ends up on the wall **farthest** from the street instead of on the street façade. The Hallway is on the wrong side (interior/central instead of flanking the west exterior side). The Balcony is off the Kitchen's far end wall rather than its right-hand side wall — minor. **Proportions.** Truth visited part ≈ 7.6 m wide × 14.1 m deep (a narrow, deep footprint). The model claims 14 × 12 m — nearly square and roughly double the width. Individual rooms: Living 5.6 × 6.4 (truth 5.9 × 4.3, too deep), Dining 6.5 × 5.2 (truth 4.5 × 3.5, much too big), Kitchen 6.5 × 4.0 (truth 4.5 × 5.3, aspect flipped). It does get Living Room as the largest room and Kitchen/Dining as mid-sized, but the overall shape is wrong. **Features.** Strong: fireplace in the Living Room on a side wall adjacent to the arched-window wall (same relative relationship as truth, though on the hall partition rather than the exterior bump-out); the large **arched window** in the Living Room; round dining table with chairs, console and chandelier; kitchen range with hood, fridge, U-shaped granite counters, sink under a window; white panel **door to the balcony** from the kitchen; front entry door (with the arched security gate) into the Foyer; sofa/coffee table/armchairs matching what the video shows. The arched window is placed on the back wall rather than the street wall, and the balcony is on the wrong kitchen wall.

## Description Approximate floor is a single level ~14m (E-W) x 12m (N-S), street/north at top. Front entry is centered on the north wall: an arched wrought-iron security gate outside, then a white entry door with a diamond textured window. The small **Foyer/Entry** (~3x2.5m) is the distribution point. Its east wall has a mirrored wood door (coat closet), its south wall has two openings: a wide cased opening with dark wood trim to the **Dining Room** on the southwest, and an arched opening to the **Living Room** on the southeast. A short central **Hallway** runs south from the foyer between Dining and Living, with doors to both and continuing south toward bedrooms (not shown) and to the Kitchen. **Living Room** (~6 x 6.5m) occupies the entire east side. North is the arch from foyer, south and east walls are exterior. The dominant feature is a large arched window/door assembly centered on the south wall (black frame, arched top). Along the east wall is a long light-grey sofa with a large abstract silver painting above it and two square wall sconces. In front of the sofa is a dark rectangular coffee table on a beige rug, with two taupe swivel armchairs facing the sofa near the arched window. The west wall holds a tiled fireplace with dark wood mantel and flanking built-in wood cabinets with arched niches above; a brass floor lamp stands left of the fireplace, a large potted plant right of it. Two small wall sconces flank artwork above the mantel. **Dining Room** (~6.5 x 5m) occupies the west-central area, accessed from the foyer/hallway via a wide double-door cased opening on its north/east side. Center is a round table with light linen and 5-6 light upholstered chairs, under a brass sputnik chandelier. The south wall has a doorway (dark wood trim, white door) into the **Kitchen**. The west wall has a rectangular window, the north wall has a second window, the east wall has a dark console table with a large gold/cream abstract painting above and a potted snake plant. A framed artwork hangs on the south wall near the kitchen door. **Kitchen** (~6.5 x 3.5m) occupies the southwest corner, accessed from Dining via the south doorway. It is U-shaped with medium honey wood cabinets, speckled grey granite counters and backsplash, stainless gas range with hood centered on the north wall, stainless fridge on the northwest, sink under a window on the east wall, dishwasher on the southeast. A small round light-wood breakfast table with 4 white chairs sits against the south wall under two tall windows. A white panel door on the south wall leads to a narrow exterior **Balcony/Lightwell** (grey siding, metal rail, hooks under window) that runs along the south exterior between buildings. Floors: Foyer and Living/Dining have light herringbone wood with dark inlay borders; Kitchen has light tile. Walls are white with dark wood base/door trim and crown molding. Camera path (described only here): starts outside the front gate looking in, pans right to the entry door, enters the foyer, looks down the hallway, pans between Dining (left) and Living (right) via the arch, enters Living and pans along sofa to arched window to fireplace, returns to foyer, goes down hallway, enters Dining, circles the table, passes through to Kitchen, circles Kitchen and breakfast area, exits to the exterior balcony/lightwell and looks back. Unsure: exact overall dimensions, exact hallway length beyond kitchen, number of chairs, precise cabinet counts, and whether the arched Living window is operable door vs fixed window. All positions are approximate from video perspective. ## Objects ```json [ {"name": "floor", "x": 0, "y": 0, "w": 14, "h": 12, "rotation_deg": 0, "confidence": "high", "notes": "overall footprint,

Strengths

• All four main visited spaces (hallway/foyer, living room, dining room, kitchen) are named with no invented rooms
• Camera sequence front door → hallway → living room → dining room → kitchen → exterior door is traceable and consistent
• Correct Living–Dining and Dining–Kitchen openings, and a balcony/back door off the kitchen's exterior wall
• Kitchen placed at the deepest end of the plan, front door and living room on the street side
• Good object inventory: fireplace, sofa, two armchairs, coffee table, round dining table, stove, fridge, kitchen table

Errors

• Kitchen drawn beside the Dining Room, in the strip that actually holds the long hallway/stairs/bathrooms, instead of directly behind the dining room
• Hallway reduced to a short stub at the entrance rather than a corridor running the full depth alongside dining room and kitchen
• Missing the Hallway–Kitchen opening
• Fireplace placed on the living room's hallway-side wall instead of the far exterior side wall
• Arched living-room window not drawn; Balcony not drawn as a room; Foyer/Entry not identified
• Footprint drawn nearly square with two large unlabelled voids, losing the narrow 7.6 × 14 m deep shape; living room drawn square rather than elongated

## Reasoning **Orientation.** The model's plan puts the front door at the top centre; the ground truth has the Entry/street side at the bottom of the page. So the model's drawing is roughly a 180° rotation of the truth. However, the rotation is not internally consistent: in the truth, the Living Room, Dining Room and Kitchen all lie on the *same* (right/east) side of the long hallway, in sequence front→back, whereas the model puts the Living Room on one side of the hallway and the Dining Room/Kitchen on the other. So part of the plan reads as mirrored relative to the rest. **Room inventory.** The model labels Hallway, Living Room, Dining Room, Kitchen — four of the five visited spaces. The Foyer is absorbed into "Hallway" (defensible, since the hallway does start at the foyer), and the Balcony appears only as a "Back Door" on the kitchen wall rather than as a room. No invented rooms are labelled, but two large areas of the footprint (top-left and bottom-right) are left blank and unlabelled, which reads as unresolved space rather than an error per se. **Topology.** Most edges are right: Front Door → Hallway; Hallway ↔ Living Room; Hallway ↔ Dining Room ("straight ahead"); Living Room ↔ Dining Room (they share the wall at the pink room's right edge); Dining Room ↔ Kitchen; Kitchen → exterior door (balcony). The truth's Hallway ↔ Kitchen opening is missing (the kitchen's corner only just grazes the hallway). The camera's sequence Foyer → Hallway → Living → Dining → Kitchen → Balcony can be traced on the model's plan without contradiction, which is the main thing. **Placement.** Correct: front door and living room on the street side; kitchen at the deepest part of the plan; balcony door on a kitchen exterior wall away from the hallway. Wrong: in the truth the Kitchen sits *behind* the Dining Room in the same band (same x-range), with the hallway, stairs and bathrooms filling the narrow left strip; the model instead puts the Kitchen *beside* the Dining Room, occupying the strip where the hallway/bath/stairs actually are, and leaves the true living-room/rear-right area blank. The hallway is drawn as a short stub between the front door and the living room instead of a long corridor running the full depth alongside dining/kitchen. The living room also fails to span the front width as it does in the truth. **Proportions.** The footprint is drawn nearly square (12 × 10 in the object list) with ~40 % blank, whereas the visited part of the truth is a narrow, deep 7.6 × 14.1 m slab. Relative room sizes are reasonable (Living Room largest, Kitchen next, Dining Room smallest; kitchen 4×6 vs truth 4.5×5.3, dining 4×4 vs 4.5×3.5), but the living room is drawn 6×6 (square) versus the truth's clearly elongated 5.9 × 4.3, and the overall depth-to-width character is lost. **Features.** Present: fireplace (but placed on the living room's hallway-side wall; in the truth it is on the opposite, far exterior wall), two armchairs, sofa, coffee table, round dining table, stove, fridge, kitchen table, front door, back/balcony door. Missing from the drawing: the arched front window (mentioned in prose only), the balcony itself as a small outdoor square off the kitchen's side wall, kitchen counters, the Entry/Foyer marking. ## Scores

## Description The video shows a first-person walkthrough of a house floor. The camera starts at the front door, entering a hallway. To the right is a living room with a large arched window, a fireplace, a sofa, a coffee table, and two armchairs. Straight ahead from the entrance is a dining room with a round table and chairs. To the left of the dining room is a kitchen with wooden cabinets, a stove, a refrigerator, and a small round table with chairs. The kitchen has a door leading to an outdoor balcony or walkway. The camera walks through these rooms, showing their layout and connections. ## Objects ```json [ { "name": "floor", "x": 0, "y": 0, "w": 12, "h": 10, "rotation_deg": 0, "confidence": "high", "notes": "Overall floor footprint" }, { "name": "hallway", "x": 4, "y": 0, "w": 2, "h": 4, "rotation_deg": 0, "confidence": "high", "notes": "Entrance hallway" }, { "name": "living_room", "x": 6, "y": 0, "w": 6, "h": 6, "rotation_deg": 0, "confidence": "high", "notes": "Living room with fireplace and arched window" }, { "name": "dining_room", "x": 4, "y": 4, "w": 4, "h": 4, "rotation_deg": 0, "confidence": "high", "notes": "Dining room with round table" }, { "name": "kitchen", "x": 0, "y": 4, "w": 4, "h": 6, "rotation_deg": 0, "confidence": "high", "notes": "Kitchen with cabinets and small table" }, { "name": "front_door", "x": 5, "y": 0, "w": 1, "h": 0.2, "rotation_deg": 0, "confidence": "high", "notes": "Main entrance door" }, { "name": "living_room_sofa", "x": 10, "y": 2, "w": 1, "h": 3, "rotation_deg": 0, "confidence": "high", "notes": "Sofa in living room" }, { "name": "living_room_coffee_table", "x": 8, "y": 2.5, "w": 1.5, "h": 1, "rotation_deg": 0, "confidence": "high", "notes": "Coffee table in living room" }, { "name": "living_room_armchair_1", "x": 7, "y": 1.5, "w": 1, "h": 1, "rotation_deg": 0, "confidence": "high", "notes": "Armchair near window" }, { "name": "living_room_armchair_2", "x": 7, "y": 3.5, "w": 1, "h": 1, "rotation_deg": 0, "confidence": "high", "notes": "Armchair near window" }, { "name": "living_room_fireplace", "x": 6, "y": 2, "w": 0.5, "h": 2, "rotation_deg": 0, "confidence": "high", "notes": "Fireplace on the left wall of living room" }, { "name": "dining_table", "x": 5, "y": 5, "w": 2, "h": 2, "rotation_deg": 0, "confidence": "high", "notes": "Round dining table" }, { "name": "kitchen_island", "x": 2, "y": 6, "w": 1, "h": 2, "rotation_deg": 0, "confidence": "medium", "notes": "Kitchen counter/island area" }, { "name": "kitchen_table", "x": 1, "y": 8, "w": 1.5, "h": 1.5, "rotation_deg": 0, "confidence": "high", "notes": "Small round table in kitchen" }, { "name": "kitchen_stove", "x": 0, "y": 6, "w": 1, "h": 1, "rotation_deg": 0, "confidence": "high", "notes": "Stove in kitchen" }, { "name": "kitchen_fridge", "x": 0, "y": 4.5, "w": 1, "h": 1, "rotation_deg": 0, "confidence": "high", "notes": "Refrigerator in kitchen" }, { "name": "back_door", "x": 0, "y": 9, "w": 1, "h": 0.2, "rotation_deg": 90, "confidence": "high", "notes": "Door leading to balcony" } ] ```
