How to Turn a Floor Plan into a 3D Render with AI
A floor plan plus a short style brief is enough to generate furnished top-down views and photorealistic interior renders. Use the floor plan templates for speed, keep one plan per generation, and treat the output as design direction, not construction documentation.

Step-by-step
- 01
Start with a clean plan image
A black-and-white dimensioned plan works best. Straighten and crop the image, and make sure room labels are legible. This image becomes the reference.
- 02
Pick a floor plan template
The template library includes 30 floor plan templates with tested prompt structures. Choose a furnished top-down view or an eye-level render and open it in the studio.
- 03
Describe the style, not the layout
The plan already fixes the layout. Use the prompt for style: warm contemporary, oak floor, cream walls, soft daylight.
- 04
Generate the top-down view first
A furnished top-down view is the fastest check that the model understood the plan before you spend credits on eye-level renders.
- 05
Generate eye-level renders room by room
Describe one room per generation, for example: living room seen from the kitchen doorway. One room per prompt gives believable camera positions.
- 06
Check walls, doors, and proportions
Compare every output against the plan: wall positions, door swings, window placements. If something drifts, re-run with a stronger keep the layout unchanged instruction.
Comparison data
| Output | Prompt focus | What to check | Typical credits |
|---|---|---|---|
| Furnished top-down view | Style and materials | Room proportions | 2 credits |
| Eye-level room render | One room + camera position | Walls, doors, windows | 2-8 credits |
| Material and colour board | Finish selections | Consistency with the renders | 2-8 credits |
Recommendations by scenario
Renovation preview
Generate the top-down view first to agree on layout, then two eye-level renders of the key room.
Client presentation
Reuse one style brief across all rooms so the set stays consistent.
Design exploration
Run the same plan through three styles (contemporary, japandi, industrial) for a direction meeting.
Concrete examples
- 01Convert this floor plan into a furnished 3D top-down view in warm contemporary style: oak flooring, cream walls, a green sofa, dining set for six, subtle shadows. Keep the wall layout exactly as drawn.
- 02Living room seen from the kitchen doorway, based on this plan: floor-to-ceiling window on the left, linen sofa, oak coffee table, soft afternoon light, photorealistic, eye level.
Limitations and pitfalls
- AI keeps wall positions on a best-effort basis; check every render against the plan.
- Dimension text and annotations are not preserved; keep the original plan for reference.
- Renders are design direction, not construction documents.

Frequently asked questions
Can AI turn a floor plan into a 3D model?+
On Kansova it generates 3D-style views from the plan image, furnished top-downs and eye-level renders. It does not export 3D model files.
What plan quality works best?+
Black lines on white, labels readable, straight and well cropped. Higher resolution means fewer misread walls.
How much does a render cost?+
Renders start at 2 credits per image on GPT Image 2, and the exact total is shown before each generation.
Can I match a specific interior style?+
Yes. Name the style and materials in the prompt, or reuse one style brief across the whole set for consistency.
