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 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,
