A8옥상방·물탱크·빨래줄·건조 허브와 녹슨 외부 철계단은 잘 보이지만, 진입 골목/마당 구조가 B보다 덜 명확하고 창 베이 반복도 다소 불확실합니다.
B9공도 가장자리에서 좁은 골목과 단순 대문, 작은 마당, 3층 적벽돌·타일 빌라, 외부 철계단과 옥상방·물탱크·빨래줄·건조대까지 가장 완전하게 충족합니다.
C7주요 건물과 외부 계단·옥상 요소는 잘 갖췄으나 배경의 읽을 수 있는 간판/문자가 뚜렷하고, 마당 쪽 4개 반복 창 베이와 전체 부지 구성은 덜 정확합니다.

Use the attached line-art only as a structural guide: translate its exact volumes, openings, levels and attached parts into real built architecture, never into line graphics or plan colors. Render a real aged multi-family villa rooftop dwelling in an outer Incheon neighborhood, with typical local vernacular materials: weathered red brick or exterior tile cladding, cement mouldings and sills, patched stucco, grime streaks below parapets, worn metalwork and faded paint. Any exterior stair shown must read as a later retrofitted steel addition, with open treads, thin stringers, support posts, pipe handrail and rust. Make the place visibly inhabited by ordinary residents through natural weathering and improvised everyday traces, but keep it unpeopled, with no readable text or signage anywhere. Avoid story-specific marks or horror details. Shoot as a photorealistic documentary location photo from a believable slightly elevated oblique camera, neutral daylight, natural color, realistic lens perspective.

Use the attached top-down architectural site plan as the sole source for footprints, proportions, placement, circulation, and relationships; translate it into real built volumes without copying any numerals, annotations, flat colours, symbols, or graphic linework. Render a real, lived-in aged multi-family villa rooftop dwelling on the outskirts of Incheon, with regionally typical red brick or exterior tile cladding, cement trim and sills, patched stucco, grime below parapets, worn waterproofed roof surfaces, rust, peeling paint, and ordinary resident wear. If an exterior stair is shown, make it a later-added steel retrofit: open treads, thin steel stringers and posts, pipe handrail, visibly separate from the building, not concrete. Let modest everyday traces appear naturally, but no people, readable text, signage, blood, apparitions, or staged story details. Use a single eye-level documentary camera in neutral daylight, photorealistic, unglamorous, believable.

Use the attached line-art structure sketch as the exact source of truth for the property’s layout, elevations, roof levels, stair placement and all built volumes; do not invent or remove architecture. Render it as a real aged multi-family villa on the outskirts of Incheon, not a grey model: weathered red brick and small exterior tile cladding, patched stucco, cement sills and mouldings, dark grime streaks below parapets, rust stains, peeling paint and damp discoloration. Make the added exterior stair a visibly later retrofit in rusty steel, with open treads, thin stringers, support posts and a pipe handrail. Dress the rooftop dwelling as lived-in between scenes: black plastic water tank, sagging clotheslines with clips and a few plain garments, worn wooden drying platform with scattered dried seokchangpo herbs, plastic basins, buckets, coiled hose, cheap planters, old slippers, taped utility cables, a small gas cylinder, and an aged iron entrance door with blank unreadable flyers wedged at the seam. Include a neglected ground-level corner with a parked bicycle and household clutter if visible in the sketch. Keep it unpeopled, no readable text, no blood, no supernatural marks. Shoot documentary photorealism from a slightly elevated oblique camera in neutral daylight, natural colors, 35mm lens, deep focus.

B (textonly45_photo_nb2_b.png)진입문·마당·낡은 벽돌/타일·외부 철계단과 옥상 요소는 좋지만, 정면 창 베이가 네 개로 반복되지 않고 3층 매스가 A보다 덜 명확하다.
C (textonly45_photo_gpt_a.png)옥탑방·물탱크·빨래줄·건조 허브와 철계단은 갖췄지만 본관이 사실상 2층으로 보이고, 네 개 반복 창 베이와 진입 동선 표현이 약하다.
D (textonly45_photo_gpt_b.png)마당·대문·옥상 소품은 보이나 본관이 2층에 가깝고 네 개 반복 창 베이가 없으며, 철계단도 ‘뒤뜰에서 옥상 랜딩’으로 오르는 배치가 덜 맞다.

A (textonly45_photo_nb2_a.png)3층 규모, 층당 4개의 창문, 후면에서 이어지는 측면 계단과 옥상 세부 묘사 등 요구된 구조를 가장 정확하게 구현했습니다.
B (textonly45_photo_nb2_b.png)외부 계단의 위치는 적절하나, 3층이 아닌 2층 건물이며 창문이 층당 3개에 불과해 주요 건축 조건을 충족하지 못했습니다.
C (textonly45_photo_gpt_a.png)요구된 층수와 창문 개수에 미달하며, 외부 계단이 건물 전면을 가로막도록 잘못 배치되어 지시사항과 크게 어긋납니다.
D (textonly45_photo_gpt_b.png)2층 구조와 3개의 창문 배열로 프롬프트와 다르며, 계단이 후면이 아닌 전면에 부착되어 구조적 오류가 존재합니다.

GPT VLM — 올라갈 수 있는가: YES
사진상 우측 외부 철제 계단은 아래쪽 지면/마당에서 접근할 수 있고, 계단참과 계단 런이 끊기지 않고 이어지며, 디딤판 간격과 경사도 사람이 오르내릴 수 있는 형태입니다. 상부도 옥상 가장자리의 계단참으로 연결되어 실제로 해당 높이까지 올라갈 수 있어 보입니다.

Gemini VLM — 올라갈 수 있는가: NO
이 계단은 물리적으로 불가능한 기하학적 구조를 가지고 있어 사람이 오르내릴 수 없습니다. 계단 단면들이 비정상적으로 겹쳐 있고 지면과 제대로 연결되어 있지 않습니다.

Use the attached flat top-down block diagram as the sole placement and proportion guide for what exists; translate its height-layer colours only into real architectural heights and volumes. Do not reproduce any numerals, annotation marks, flat fills, outlines, or diagram graphics. Render a photorealistic, unpeopled, currently lived-in aged multi-family villa rooftop dwelling in the outskirts of Incheon, with believable ordinary residential wear, grime, repairs, fading, stains, and modest improvised household traces. Use real regional materials: aged red brick or exterior tile cladding, cement mouldings and sills, weathered stucco patches, dark streaks below parapets, rusted metalwork, worn concrete roof surfaces. Where the diagram indicates an exterior stair, make it a later-added steel retrofit with open treads, thin stringers, support posts, and pipe handrail, visibly separate from the building. Shoot from one natural eye-level documentary camera viewpoint in neutral daylight. No readable text, signage, supernatural marks, blood, or story-specific details.

Use the attached top-down block diagram as the only placement and height guide for the property, translating every footprint into real built volume and every height-layer colour into physical height only. Never reproduce its numerals, flat colours, outlines, labels, or diagram graphics. Render a photorealistic present-day exterior of an aged Incheon outskirts multi-family villa with a rooftop dwelling, lived-in by ordinary residents: varied weathering, practical repairs, modest everyday traces, and no staged drama. Use real regional materials, not diagram colours: aged red brick or exterior tile cladding, cement mouldings and sills, patched stucco, grime below parapets, dull metalwork, worn roof surfaces. The retrofitted exterior stair must read as a later-added rusty steel structure with open treads, thin stringers, support posts, and pipe handrails. Turn surrounding placeholder blocks into believable neighbouring low-rise buildings and street texture. Unpeopled, no readable text or signage. Shoot in neutral daylight, documentary eye-level realism.

The FIRST attached image is a flat TOP-DOWN BLOCK REFERENCE of the
same property: use it only for WHAT exists and WHERE things sit in
plan. Its numerals are annotations — never draw them. Its flat
colours encode height layers only; the layer order is given below —
translate those layers into clearly visible built heights.

THE PLACE (authored description — the content ground truth):
BUILDING: The main building is an old multifamily villa block, drawn as an assumed three-storey body below the rooftop unit because the script only states an old villa with a rooftop room. Its mass is a plain rectangular concrete volume set behind an entry yard. The roof is flat and usable as a cement-surfaced terrace. The front facade facing the yard should show four repeated window bays per storey, matching the extracted layout’s inferred facade-window rhythm.
TOP UNIT & DECK: The topmost enclosed unit is a small, old rooftop dwelling set on the flat terrace, drawn as a simple rectangular shell. Its boundary openings are one iron entrance door facing the stair landing, one small living-room window on a side wall, and one bedroom window on another wall. Around it, the open deck has a low concrete parapet or wall, a round water tank, a fixed laundry line, and a low platform on the cement surface.
GROUNDS: At ground level, a street edge feeds a narrow alley along the left side, leading to a single entry gate and a small recessed yard at the villa entrance. Neighboring building masses close the rear and sides, making the approach compact. From the yard’s back corner, a later-added exterior steel stair is fixed to the outside wall, with open treads, thin stringers, support posts, and a pipe handrail, continuing up to the rooftop terrace and iron-door landing.
THE PLAN MUST SHOW: The finished top-down site plan should show a rectangular villa mass centered behind the yard, with its flat roof terrace visible as the primary upper surface. Place the rooftop room as a smaller rectangle on the terrace, with one door toward the stair landing and two windows on separate sides. Draw the left alley, entry gate, recessed yard, surrounding neighbor blocks, low roof wall, fixed rooftop fixtures, and the retrofitted steel stair as a separate exterior structure attached to the building wall.

HEIGHT LAYERS (low to high): Ground (h=0) -> Stair run (h=1.5) -> Roof deck (h=3) -> Rooftop room (h=4)

Draw ONE DETAILED LINE SKETCH of the property's structure — clean
thin dark lines on plain white, like an architect's developed
massing sketch. Viewpoint: slightly elevated three-quarter oblique
view (tilted about 30 degrees down from vertical) so RELATIVE
HEIGHTS read clearly — which volume rises above which, how many
storeys the building has, what sits on top of what, and how the
stair climbs between levels.
MORE DETAIL than a plain massing sketch: draw each structural
element with its characteristic built form in lines — stair treads
and railing lines, parapet and roof edges, door and window openings
with simple frames, fixture outlines with their stands or supports
— enough that every element reads as what it is.
STILL LINES ONLY: no colours, no fills, no shading, no materials,
no texture, no photorealism. Never any interior of enclosed units.
No text, letters, numbers, labels, markers, legend or compass.
No people, no props, no vehicles.

The attached image is a PHOTOGRAPH of one real property.
TRANSLATE its permanent structural layout into the top-down
architectural SITE PLAN described below — faithful to the
photograph's actual arrangement: positions, connections,
boundary openings, and the exterior stair route between levels.
Permanent structure only: ignore people, loose objects and
movable props.

STRICT VERTICAL TOP-DOWN ONLY: this drawing is a TRUE ORTHOGRAPHIC
PLAN seen from DIRECTLY ABOVE — absolutely NO 3D, NO 2.5D, NO
axonometric or oblique tilt of any kind, no facades, no volume
sides visible; every element appears only as its pure plan
geometry (roof outlines, ground shapes, openings set in walls).

EXTERIOR ONLY: this is an OUTDOOR site plan seen from above — show
only the exterior: ground areas, building outer shells, roof-level
surfaces and outdoor fixtures. NEVER draw any interior room, inner
wall, partition or furniture of any enclosed unit — every enclosed
volume stays sealed (outer walls and boundary openings only).

Draw ONE strict TOP-DOWN 2D architectural SITE PLAN in the drafting
language of a clean floor plan — thin dark outlines, flat muted colour
fills, detailed plan symbols (double-line walls, door leaf + swing arc,
window frames set in walls, stair treads with stringers and landings,
base rings for round fixtures, paving joints, kerb lines). Height
levels appear only as flat fill tints (darker = higher). Flat
orthographic plan view: NO 3D, NO axonometric, NO perspective, no
shadows. Neutral document: no people, no story props, no vehicles, no
posted papers, no text, no letters, no numbers, no markers, no legend,
no compass. Never expose interior rooms or furniture of any enclosed
unit — outer shell and boundary openings only.

KEY ELEMENTS (letters are identifiers only — mark each listed element's POSITION on the plan with its circled letter):
LEVELS (placement logic only): ground -> villa mass, 3 storeys roof terrace -> rooftop room and rooftop fixtures
Context: public road edge and neighbouring building masses border the alley, rear, and side.
A. narrow alley, ground approach from the public road edge to the entry gate, facing the yard sequence.
B. entry gate, boundary opening between the narrow alley and the entry yard.
C. entry yard, ground yard inside the gate before the villa, with a rear part connecting to the exterior stair route.
D. villa mass, 3-storey building mass behind the entry yard, hosting the roof terrace and the exterior stair on its outside wall.
E. facade windows, exterior window bays in the villa wall facing the entry yard, four repeated bays per storey.
F. roof terrace, exterior rooftop surface on the villa mass around the rooftop room, with the stair landing and rooftop fixtures on it.
G. low wall, low climbable boundary on the roof terrace edge around the rooftop room area, in the sightline toward a rooftop-room window.
H. rooftop room, small enclosed volume on the roof terrace, with its front side facing the stair landing.
I. added-on exterior stair, separate later stair attached to the villa outside wall, connecting the entry-yard level to the roof terrace landing in front of the rooftop room.
J. iron door, exterior entrance threshold in the rooftop room front wall, facing the roof terrace landing and opening into the rooftop room.
K. living window, small exterior window in a side wall of the rooftop room, facing the roof terrace and low-wall area.
L. bedroom window, exterior window in another outer wall of the rooftop room.
M. water tank, round utility fixture on the roof terrace near the rooftop room.
N. laundry line, thin exterior line on the roof terrace between the water tank and the rooftop room.
O. low platform, low fixture on the roof terrace near the approach to the iron door.

Draw ONE strict TOP-DOWN 2D architectural SITE PLAN in the drafting
language of a clean floor plan — thin dark outlines, flat muted colour
fills, detailed plan symbols (double-line walls, door leaf + swing arc,

posted papers, each listed element carries ONLY its assigned letter, drawn once
as a small plain CIRCLED LETTER marker on (or beside) it; apart
from these circled letters no text, no words, no numbers, no other
markers, no legend, no compass. Never expose interior rooms or furniture of any enclosed
unit — outer shell and boundary openings only.

THE PLACE (authored description — the content ground truth):
BUILDING: The main building is an old multifamily villa block, drawn as an assumed three-storey body below the rooftop unit because the script only states an old villa with a rooftop room. Its mass is a plain rectangular concrete volume set behind an entry yard. The roof is flat and usable as a cement-surfaced terrace. The front facade facing the yard should show four repeated window bays per storey, matching the extracted layout’s inferred facade-window rhythm.
TOP UNIT & DECK: The topmost enclosed unit is a small, old rooftop dwelling set on the flat terrace, drawn as a simple rectangular shell. Its boundary openings are one iron entrance door facing the stair landing, one small living-room window on a side wall, and one bedroom window on another wall. Around it, the open deck has a low concrete parapet or wall, a round water tank, a fixed laundry line, and a low platform on the cement surface.
GROUNDS: At ground level, a street edge feeds a narrow alley along the left side, leading to a single entry gate and a small recessed yard at the villa entrance. Neighboring building masses close the rear and sides, making the approach compact. From the yard’s back corner, a later-added exterior steel stair is fixed to the outside wall, with open treads, thin stringers, support posts, and a pipe handrail, continuing up to the rooftop terrace and iron-door landing.
THE PLAN MUST SHOW: The finished top-down site plan should show a rectangular villa mass centered behind the yard, with its flat roof terrace visible as the primary upper surface. Place the rooftop room as a smaller rectangle on the terrace, with one door toward the stair landing and two windows on separate sides. Draw the left alley, entry gate, recessed yard, surrounding neighbor blocks, low roof wall, fixed rooftop fixtures, and the retrofitted steel stair as a separate exterior structure attached to the building wall.

LAYOUT RELATIONS (approximate — honour what exists and rough relations, NOT exact geometry):

- any facade windows sit apart with clear wall between them, aligned to the building's real storeys — never touching.
- CORRECTION (production owner): the exterior stair element is an ADDED-ON STEEL stair retrofitted later onto its building's outside wall — open treads, thin steel stringers and support posts, pipe handrail, visibly a separate later addition to the building. It is NOT concrete or cement; this supersedes any cement/concrete stair mention elsewhere in the data.

Draw the plan VERY DETAILED — real working-drawing density, so that

plan vocabulary per element type:

- alleys: paving joints

Use the attached line-art only as a structural guide: translate its exact volumes, openings, levels and attached parts into real built architecture, never into line graphics or plan colors. Render a real aged multi-family villa rooftop dwelling in an outer Incheon neighborhood, with typical local vernacular materials: weathered red brick or exterior tile cladding, cement mouldings and sills, patched stucco, grime streaks below parapets, worn metalwork and faded paint. Any exterior stair shown must read as a later retrofitted steel addition, with open treads, thin stringers, support posts, pipe handrail and rust. Make the place visibly inhabited by ordinary residents through natural weathering and improvised everyday traces, but keep it unpeopled, with no readable text or signage anywhere. Avoid story-specific marks or horror details. Shoot as a photorealistic documentary location photo from a believable slightly elevated oblique camera, neutral daylight, natural color, realistic lens perspective.

Use the attached top-down architectural site plan as the sole source for footprints, proportions, placement, circulation, and relationships; translate it into real built volumes without copying any numerals, annotations, flat colours, symbols, or graphic linework. Render a real, lived-in aged multi-family villa rooftop dwelling on the outskirts of Incheon, with regionally typical red brick or exterior tile cladding, cement trim and sills, patched stucco, grime below parapets, worn waterproofed roof surfaces, rust, peeling paint, and ordinary resident wear. If an exterior stair is shown, make it a later-added steel retrofit: open treads, thin steel stringers and posts, pipe handrail, visibly separate from the building, not concrete. Let modest everyday traces appear naturally, but no people, readable text, signage, blood, apparitions, or staged story details. Use a single eye-level documentary camera in neutral daylight, photorealistic, unglamorous, believable.

The FIRST attached image is a top-down SITE-PLAN REFERENCE of the
same property: use it only for WHAT exists and WHERE things sit in
plan. Its numerals are annotations — never draw them. The height
layer order is given below — translate those levels into clearly
visible built heights.

THE PLACE (authored description — the content ground truth):
BUILDING: The main building is an old multifamily villa block, drawn as an assumed three-storey body below the rooftop unit because the script only states an old villa with a rooftop room. Its mass is a plain rectangular concrete volume set behind an entry yard. The roof is flat and usable as a cement-surfaced terrace. The front facade facing the yard should show four repeated window bays per storey, matching the extracted layout’s inferred facade-window rhythm.
TOP UNIT & DECK: The topmost enclosed unit is a small, old rooftop dwelling set on the flat terrace, drawn as a simple rectangular shell. Its boundary openings are one iron entrance door facing the stair landing, one small living-room window on a side wall, and one bedroom window on another wall. Around it, the open deck has a low concrete parapet or wall, a round water tank, a fixed laundry line, and a low platform on the cement surface.
GROUNDS: At ground level, a street edge feeds a narrow alley along the left side, leading to a single entry gate and a small recessed yard at the villa entrance. Neighboring building masses close the rear and sides, making the approach compact. From the yard’s back corner, a later-added exterior steel stair is fixed to the outside wall, with open treads, thin stringers, support posts, and a pipe handrail, continuing up to the rooftop terrace and iron-door landing.
THE PLAN MUST SHOW: The finished top-down site plan should show a rectangular villa mass centered behind the yard, with its flat roof terrace visible as the primary upper surface. Place the rooftop room as a smaller rectangle on the terrace, with one door toward the stair landing and two windows on separate sides. Draw the left alley, entry gate, recessed yard, surrounding neighbor blocks, low roof wall, fixed rooftop fixtures, and the retrofitted steel stair as a separate exterior structure attached to the building wall.

HEIGHT LAYERS (low to high): Ground (h=0) -> Stair run (h=1.5) -> Roof deck (h=3) -> Rooftop room (h=4)

Draw ONE SIMPLE LINE SKETCH of the property's structure — clean thin
dark lines on plain white, like a quick architect's massing sketch.
Viewpoint: slightly elevated three-quarter oblique view (tilted about
30 degrees down from vertical) so RELATIVE HEIGHTS read clearly —
which volume rises above which, how many storeys the building has,
what sits on top of what, and how the stair climbs between levels.
LINES ONLY: no colours, no fills, no shading, no materials, no
texture, no photorealism.
SIMPLE: massing outlines, level edges and openings only — no
drafting detail, no double-line walls, no furniture, never any
interior of enclosed units.
No text, letters, numbers, labels, markers, legend or compass.

Use the attached line-art structure sketch as the exact source of truth for the property’s layout, elevations, roof levels, stair placement and all built volumes; do not invent or remove architecture. Render it as a real aged multi-family villa on the outskirts of Incheon, not a grey model: weathered red brick and small exterior tile cladding, patched stucco, cement sills and mouldings, dark grime streaks below parapets, rust stains, peeling paint and damp discoloration. Make the added exterior stair a visibly later retrofit in rusty steel, with open treads, thin stringers, support posts and a pipe handrail. Dress the rooftop dwelling as lived-in between scenes: black plastic water tank, sagging clotheslines with clips and a few plain garments, worn wooden drying platform with scattered dried seokchangpo herbs, plastic basins, buckets, coiled hose, cheap planters, old slippers, taped utility cables, a small gas cylinder, and an aged iron entrance door with blank unreadable flyers wedged at the seam. Include a neglected ground-level corner with a parked bicycle and household clutter if visible in the sketch. Keep it unpeopled, no readable text, no blood, no supernatural marks. Shoot documentary photorealism from a slightly elevated oblique camera in neutral daylight, natural colors, 35mm lens, deep focus.

The attached image is a PHOTOGRAPH of one real property — it
replaces the structure lines: EXTRACT the placement structure
(what contains or carries what, roughly where, how the exterior
stair connects the levels) from the photograph itself, and stay
faithful to its actual arrangement. Permanent structure only:
ignore people, loose objects and movable props.

Draw ONE SCHEMATIC BLOCK DIAGRAM of a real property's layout — the
kind of flat figure a computer program draws: plain solid-colour
shapes on a plain light background, uniform thin dark outlines.
Flat schematic drawing language always: no gradients, no shadows,
no texture, no photorealism.
VIEWPOINT — top-down, or AT MOST a gentle axonometric tilted about
30 degrees from vertical (2.5D) so slight height reads. NEVER full
3D perspective, never vanishing-point depth, never eye-level,
never a facade as the main subject. Any level difference read from the
photograph is placement logic, not an instruction to build tall 3D
volumes.
The attached photograph gives the placement structure (what is on/in
what, roughly where). Everything beyond that placement — exact shapes,
sizes, proportions, spacing — YOU decide, so the property reads
plausibly; keep every extracted relation true.
Every building is ONE solid block — never any interior rooms, inner
walls or furniture.
No text, letters, numbers, labels, markers, legend or compass anywhere.
No people, no props, no vehicles.

SPATIAL LAYOUT — what is where (containment, relative position & size, levels, spacing). Draw exactly these relations as blocks:
- The villa stands behind the alley gate, with its entrance yard at ground level.
- The main villa rises about three or four storeys below the rooftop level.
- The yard fills the front ground approach, and its rear corner stays tucked away.
- The added-on exterior stair begins at that rear corner against an outside wall.
- The stair climbs the wall from ground level to the rooftop in a narrow run.
- The stair top meets the rooftop open deck beside the rooftop room.
- The rooftop open deck sits on the villa roof, outside the rooftop room.
- The rooftop room occupies a small share of the roof as one enclosed unit.
- The entry door is on the unit wall facing the open deck.
- The door stands a few steps from the stair top across the deck.
- A small window opens from the unit wall above the rooftop level.
- The water tank sits on one side of the rooftop open deck.
- The clothesline stretches across an open part of the deck near the tank.
- The drying platform sits low on the deck near the clothesline.
- The stair-to-door path crosses the deck past these rooftop fixtures.
- From the alley, movement goes through gate, yard, rear stair, deck, then door.

Draw ONE SCHEMATIC BLOCK DIAGRAM of a real property's layout — the kind
of flat figure a computer program draws: strict TOP-DOWN 2D, plain
solid-colour rectangles and circles on a plain light background, uniform
thin dark outlines. ABSOLUTELY FLAT: no bevels, no edge highlights, no
gradients, no shadows, no shading, no texture, no perspective, no 3D
feel of any kind — every block is one uniform colour region with a plain
outline. PURPOSE: structural comprehension only. Every building is ONE
solid block — never any interior rooms, inner walls or furniture.
No text, letters, numbers, labels, markers, legend or compass anywhere.
No people, no props, no vehicles.

Edit this photograph. The exterior metal staircase on the building
is structurally impossible: flights overlap, connections between
runs and landings are broken, the bottom run does not reach the
ground, and railings pass through structure.
REDRAW THE STAIRCASE ONLY, as ONE physically climbable retrofit
steel stair: continuous flights with even open treads, landings
that actually connect each run, the bottom run reaching the
ground / yard level, the top run arriving at the rooftop landing,
railings and support posts continuous and never intersecting any
structure. Keep its rusty, added-on steel character and its
position against the same wall.
PRESERVE EVERYTHING ELSE EXACTLY as in the original photograph —
buildings, roof objects, yard, surroundings, lighting, camera,
framing. No people, no readable text anywhere.

Create a photorealistic documentary location image of an aged multi-family villa in the outskirts of Incheon, seen from an elevated three-quarter angle about 45 degrees above and off to one side, fitting the whole property in frame. Show a narrow alley from the public road edge leading to a simple entry gate, then a small entry yard before a three-storey villa mass. The villa has aged red brick and exterior tile cladding, cement mouldings and sills, patched stucco, grime streaks under parapets, and four repeated window bays per storey facing the yard. Attach a clearly later-added open steel stair to the outside wall, with thin stringers, open treads, support posts, rusty pipe handrails, rising from the rear of the yard to the roof terrace landing. On the roof terrace place a small rooftop room with a worn iron door facing the landing, small side windows, a low parapet wall, round water tank, sagging laundry line, and a low platform with scattered dried herbs. Surround it with ordinary low-rise neighboring buildings, utility wires, pipes, roof clutter, stained concrete paving, no people, no readable text, neutral daylight.

The attached image is a PHOTOGRAPH of one real property.
TRANSLATE its permanent structural layout into the top-down
architectural SITE PLAN described below — faithful to the
photograph's actual arrangement: positions, connections,
boundary openings, and the exterior stair route between levels.
Permanent structure only: ignore people, loose objects and
movable props.

OUTPUT MEDIUM: a flat 2D architectural SITE-PLAN DRAWING on plain
drawing paper — NOT a photograph, NOT a rendering of the scene.
The attached photograph is ONLY a source of layout information;
do NOT reproduce or imitate its camera angle or its look —
RE-PROJECT everything to a TRUE ORTHOGRAPHIC PLAN seen from
DIRECTLY ABOVE (90 degrees, straight-down nadir).
Absolutely NO 3D of any kind: no perspective, no foreshortening,
no axonometric or oblique tilt, no facades, no wall surfaces, no
volume sides, no cast shadows, no photographic texture — every
element appears ONLY as its pure plan geometry (roof outlines,
ground shapes, openings marked in wall lines) in uniform flat
fills and clean drafting linework.

EXTERIOR ONLY: this is an OUTDOOR site plan seen from above — show
only the exterior: ground areas, building outer shells, roof-level
surfaces and outdoor fixtures. NEVER draw any interior room, inner
wall, partition or furniture of any enclosed unit — every enclosed
volume stays sealed (outer walls and boundary openings only).

KEY ELEMENTS (letters are identifiers only — mark each listed element's POSITION on the plan with its circled letter). Elements that face sideways and are not visible from directly above (windows or doors set in walls) appear ONLY as their opening symbols on the wall line, with the circled letter beside that symbol — NEVER fold or draw any facade or elevation into the plan to show them:
LEVELS (placement logic only): ground -> villa mass, 3 storeys roof terrace -> rooftop room and rooftop fixtures
Context: public road edge and neighbouring building masses border the alley, rear, and side.
A. narrow alley, ground approach from the public road edge to the entry gate, facing the yard sequence.
B. entry gate, boundary opening between the narrow alley and the entry yard.
C. entry yard, ground yard inside the gate before the villa, with a rear part connecting to the exterior stair route.
D. villa mass, 3-storey building mass behind the entry yard, hosting the roof terrace and the exterior stair on its outside wall.
E. facade windows, exterior window bays in the villa wall facing the entry yard, four repeated bays per storey.
F. roof terrace, exterior rooftop surface on the villa mass around the rooftop room, with the stair landing and rooftop fixtures on it.
G. low wall, low climbable boundary on the roof terrace edge around the rooftop room area, in the sightline toward a rooftop-room window.
H. rooftop room, small enclosed volume on the roof terrace, with its front side facing the stair landing.
I. added-on exterior stair, separate later stair attached to the villa outside wall, connecting the entry-yard level to the roof terrace landing in front of the rooftop room.
J. iron door, exterior entrance threshold in the rooftop room front wall, facing the roof terrace landing and opening into the rooftop room.
K. living window, small exterior window in a side wall of the rooftop room, facing the roof terrace and low-wall area.
L. bedroom window, exterior window in another outer wall of the rooftop room.
M. water tank, round utility fixture on the roof terrace near the rooftop room.
N. laundry line, thin exterior line on the roof terrace between the water tank and the rooftop room.
O. low platform, low fixture on the roof terrace near the approach to the iron door.

Edit this architectural site-plan DRAWING. Fix ONLY the points listed below, each in place:

CORRECTIONS:
- Move the rooftop structure (H) downwards so it is entirely contained within the main rectangular boundary of the roof (F), making the top parapet line straight.

PRESERVE EVERYTHING ELSE EXACTLY as in the attached drawing — same straight-down plan view, same layout, same drafting style, same circled letter markers in their places. Apart from the circled letters no text anywhere.

CORRECTIONS:
- Enlarge structure H into a large rectangle and move it to the front-left edge of the roof.
- Rotate table O 90 degrees so its long axis is parallel to the front facade.
- Redraw the front facade footprint to have a single central recess with flush left and right blocks.

G. low wall, terrace and yard edges + perimeter around the roof terrace and front yard boundary, low continuous strip + attaches to the terrace edge, stair landing, and gate-side yard wall.
H. rooftop room, roof terrace + rear-center/right of the terrace, small box compared with the terrace + connects to the roof terrace through the iron door.
I. added-on exterior stair, outside face of the villa mass + right side of the building, large linear steel stair + connects the entry-yard/right-side ground area to the roof terrace landing.
J. iron door, rooftop room + terrace-facing side of the rooftop room, narrow rusty door panel + connects the rooftop room interior to the roof terrace.

Draw ONE strict TOP-DOWN 2D architectural SITE PLAN in the drafting
language of a clean floor plan — thin dark outlines, flat muted colour
fills, detailed plan symbols (double-line walls, door leaf + swing arc,
window frames set in walls, stair treads with stringers and landings,
base rings for round fixtures, paving joints, kerb lines). Height
levels appear only as flat fill tints (darker = higher). Flat
orthographic plan view: NO 3D, NO axonometric, NO perspective, no
shadows. Neutral document: no people, no story props, no vehicles, no
posted papers, each listed element carries ONLY its assigned letter, drawn once
as a small plain CIRCLED LETTER marker on (or beside) it; apart
from these circled letters no text, no words, no numbers, no other
markers, no legend, no compass. Never expose interior rooms or furniture of any enclosed
unit — outer shell and boundary openings only.

CORRECTIONS — a previous attempt of this plan got the points below wrong; draw them correctly this time:
- Indent the central section of the front wall to represent the recessed balconies.
- Redraw the roof structure (O) as a wide, solid rectangular platform.

OUTPUT MEDIUM: a flat 2D architectural SITE-PLAN DRAWING on plain
drawing paper — NOT a photograph, NOT a rendering of the scene.
Draw a TRUE ORTHOGRAPHIC PLAN seen from DIRECTLY ABOVE
(90 degrees, straight-down nadir).
Absolutely NO 3D of any kind: no perspective, no foreshortening,
no axonometric or oblique tilt, no facades, no wall surfaces, no
volume sides, no cast shadows, no photographic texture — every
element appears ONLY as its pure plan geometry (roof outlines,
ground shapes, openings marked in wall lines) in uniform flat
fills and clean drafting linework.

EXTERIOR ONLY: this is an OUTDOOR site plan seen from above — show
only the exterior: ground areas, building outer shells, roof-level
surfaces and outdoor fixtures. NEVER draw any interior room, inner
wall, partition or furniture of any enclosed unit — every enclosed
volume stays sealed (outer walls and boundary openings only).

KEY ELEMENTS (letters are identifiers only — mark each listed element's POSITION on the plan with its circled letter). Elements that face sideways and are not visible from directly above (windows or doors set in walls) appear ONLY as their opening symbols on the wall line, with the circled letter beside that symbol — NEVER fold or draw any facade or elevation into the plan to show them:
LEVELS (placement logic only): narrow alley and entry yard occupy the ground plane; a large four-storey villa mass fills the plot; the roof terrace occupies the villa footprint and contains the low wall, rooftop room, water tank, laundry line, low platform, and the exterior-stair landing.
Context: unnamed neighboring villa masses press close at left, rear, and right, with narrow gaps, roof terraces, tanks, and utility lines surrounding the surveyed villa.
A. narrow alley, public lane + front-left along the villa plot + connects to the entry gate and continues between neighboring masses.
B. entry gate, perimeter wall + front-left of the entry yard, small compared with the yard width + connects the narrow alley to the entry yard.
C. entry yard, inside the front perimeter wall + front of the villa mass, compact paved court + connects the entry gate to the ground-floor entrance area and the base of the added-on exterior stair.
D. villa mass, main plot footprint + center-right of the photograph, large four-storey block + attaches to the entry yard at the front and to the added-on exterior stair along the right side.
E. facade windows, villa mass wall faces + front and right flanks in repeated vertical groups, medium-sized relative to the bays + connect interior rooms to balconies, yard side, and stair side.
F. roof terrace, roof area within the villa footprint + broad rectangular area across the villa, larger than the rooftop room + connects to the low wall, rooftop room, water tank, laundry line, low platform, and added-on exterior stair landing.
G. low wall, terrace and yard edges + perimeter around the roof terrace and front yard boundary, low continuous strip + attaches to the terrace edge, stair landing, and gate-side yard wall.
H. rooftop room, roof terrace + rear-center/right of the terrace, small box compared with the terrace + connects to the roof terrace through the iron door.
I. added-on exterior stair, outside face of the villa mass + right side of the building, large linear steel stair + connects the entry-yard/right-side ground area to the roof terrace landing.
J. iron door, rooftop room + terrace-facing side of the rooftop room, narrow rusty door panel + connects the rooftop room interior to the roof terrace.
K. living window, villa mass + front-center bay facing the entry yard, larger sliding window group than nearby small windows + connects the living area to the balcony/front yard side.

Edit this architectural site-plan DRAWING. Fix ONLY the points listed below, each in place:

CORRECTIONS:
- Move the clothesline to the front-left area of the roof.
- Move the platform to the center-right area, adjacent to the roof structure.

PRESERVE EVERYTHING ELSE EXACTLY as in the attached drawing — same straight-down plan view, same layout, same drafting style, same circled letter markers in their places. Apart from the circled letters no text anywhere.

Create a photorealistic documentary location image of an aged multi-family villa in the outskirts of Incheon, seen from an elevated three-quarter angle about 45 degrees above and off to one side, fitting the whole property in frame. Show a narrow alley from the public road edge leading to a simple entry gate, then a small entry yard before a three-storey villa mass. The villa has aged red brick and exterior tile cladding, cement mouldings and sills, patched stucco, grime streaks under parapets, and four repeated window bays per storey facing the yard. Attach a clearly later-added open steel stair to the outside wall, with thin stringers, open treads, support posts, rusty pipe handrails, rising from the rear of the yard to the roof terrace landing. On the roof terrace place a small rooftop room with a worn iron door facing the landing, small side windows, a low parapet wall, round water tank, sagging laundry line, and a low platform with scattered dried herbs. Surround it with ordinary low-rise neighboring buildings, utility wires, pipes, roof clutter, stained concrete paving, no people, no readable text, neutral daylight.
top_photo_fixed_nb2.png
Edit this photograph. Fix ONLY the issues listed below, each in
place, changing nothing else about the property:

ISSUES TO FIX:
- (GPT VLM) Make the yard-facing facade show exactly four repeated window bays on each storey.
- (GPT VLM) Move the added exterior steel stair so it starts from the rear of the entry yard.
- (GPT VLM) Add a clear roof-terrace landing and parapet opening where the exterior stair reaches the roof.
- (GPT VLM) Keep only one worn iron door on the rooftop room and orient it toward the stair landing.
- (GPT VLM) Reduce the rooftop room to a small rooftop room while preserving its placement and details.
- (Gemini VLM) Remove the railing at the top stair landing to open access to the roof.
- (Gemini VLM) Redesign the front facade to display exactly four repeated window bays per storey.
- (Gemini VLM) Relocate the bottom of the steel stair to start from the rear of the yard.

PRESERVE EVERYTHING ELSE EXACTLY as in the original photograph —
buildings, roof objects, yard, surroundings, lighting, camera,
framing. No people, no readable text anywhere.
