AI House and Apartment Floor Plans Furnished, with room areas

Describe one storey of a house or an apartment by its outside size and rooms, and the AI draws a furnished plan with beds, kitchen, bathroom fixtures and living room furniture. Each room is labelled with its measured area in m², and the drawing opens in the viewer as a DWG on an A3 sheet.

Free. Use your own Anthropic or OpenAI key.

Also from Innerscene: Circadian Lab, a free lighting calculator for room illuminance, melanopic EML, and glare.

Need the whole building as a BIM model? The AI can also build IFC buildings with storeys, walls, doors, windows, rooms and lights.

How it works

  1. 1. Describe it or add a photoType what you want in plain words, with sizes if you know them, or add a photo as a reference. Describe an object or a person.
  2. 2. The AI builds and checks itThe AI writes an OpenSCAD program for an object, or sets up the character generator for a person. It looks at six rendered views of the result and fixes what is wrong, up to five builds per message.
  3. 3. Refine and exportThe model opens in the viewer at real size. Ask for changes in the chat, move the sliders, then download it or pick a format from the Export menu.

Why make it with AI here

  • Bed sets, dining for 4 or 6 and sofa sets show whether the furniture fits before anything is built.
  • Room areas in m² are measured from the drawn walls, which makes two layouts easy to compare.
  • Kitchens and bathrooms get counters, fridge, stove, sinks, WC, basin, shower or bath, and a washer where you ask for one.

Getting the house plan out

  1. Download the DWG to edit the plan in CAD.
  2. Choose PDF in the Export menu to print or share the plan at scale.
  3. Choose PNG or SVG for an image to send to a builder or family member.

The PDF export is vector, so it prints sharply on A3 at the sheet scale. Furniture symbols are generic; swap in your own blocks in CAD where a specific product matters.

Best export formats: DWG, PDF (vector), DXF

Good to know

Each drawing is one storey, so make each floor of a larger house in its own chat. Stairs, roofs and elevations are not drawn, and there is no building code check.

Cost and privacy

You use your own Anthropic or OpenAI API key. It is stored only in your browser and sent only to that provider, which bills you directly: a model typically costs $0.05 to $0.30 at Standard quality and up to about $1 at Detailed, and Innerscene charges nothing. Your key and prompts are not sent to Innerscene; we record anonymous usage statistics such as the steps used, the model chosen, token counts, a cost estimate and whether a model was made.

Questions

▶Can it draw a two-storey house?
It draws one storey per drawing. Describe each floor separately and keep the outside walls the same size on both.
▶How are room areas measured?
The engine measures each enclosed room from the drawn walls and writes its name and area in m² inside the room, placed clear of the furniture.
▶Can I move a door or change which way it opens?
Yes. Ask in the chat, for example "swap the hinge on the bathroom door", or move the door block yourself in CAD.
▶Is the plan good enough for a building permit?
No. It is a starting layout with no building code check. An architect or designer needs to develop and check it before any permit application.
