The production floor_plan_prompt baseline collapsed 'private_bedroom_a' and 'private_bedroom_b' into a single bedroom. The screenplay explicitly treats them as two distinct, separately accessed bedrooms ('안방' / '민숙 방' and '수리영 방'). I have split these into two separate enclosed bedrooms in the revise

A flat 2D schematic top-down floor plan of a small South Korean rooftop apartment, clean vector line style on off-white background with pastel color-coded room fills. The apartment has a central living dining area filled pale yellow, a small kitchen nook in the northwest filled pale green, a private bedroom A on the east filled pale blue, a private bedroom B on the northeast filled pale orange, a compact bathroom filled pale cyan, and an entry alcove filled pale beige. Includes symbols for sliding windows on the west and east walls, a front door, interior bedroom doors, dining table, kitchen counter with sink, a bed in bedroom A, and a bed in bedroom B. Circular markers with numbers label the zones and fixtures. No text, no perspective, no 3D rendering.
Split the single generic bedroom from production into two separate bedrooms (private bedroom A and private bedroom B) to respect the screenplay's explicit multi-bedroom layout while preserving continuity of the relative plot devices.

  • #1 corridor path (area; unit=)
  • #2 heavy metal doors (opening; unit=)
  • #3 oblique wire cages (fixture; unit=)
  • #4 concrete walls (fixture; unit=)
  • #5 kennel rows (area; unit=)
A flat 2D schematic top-down floor plan of an institutional animal shelter corridor, clean vector line style on a pale gray background. The plan shows a long central hallway corridor flanked on both sides by rows of wire cages drawn with neat parallel metal grid symbols. Heavy metal door swings are shown at both ends of the corridor. Solid concrete walls enclose the layout with simple single-weight outlines. Circular markers with numbers label the cages, doors, and corridor space. No perspective, no 3D effects, no text.
Created a new schematic floor plan for this location as there is no existing production equivalent, structuring it around the cages and heavy doors highlighted in the director brief.
fp_l11_01L11|exterior4
  • #2 rooftop landing area (area; unit=)
  • #3 exterior stair flight (furniture; unit=)
  • #5 half-open iron rooftop door (opening; unit=)
  • #9 concrete wall (fixture; unit=)
A flat 2D schematic top-down floor plan of an exterior concrete staircase ascending to a rooftop landing, clean vector line style on an off-white background. The yard at the bottom is colored pale beige, the staircase run is pale gray, and the small landing platform at the top is pale blue-gray. Shows an iron door symbol on the north wall swinging inward. Railings are indicated by fine parallel lines along the open stair edge. Circular markers with numbers label the staircase, landing area, door, and wall. No text, no perspective, no 3D shading.
Aligned the rooftop landing plate exactly with the staircase structure (fp_villa_rooftop_stairs) instead of the yard plan, ensuring structural continuity.
