How AI turns a floor plan into interior design concepts
A step-by-step look at how Kansumi reads your floor plan, validates the geometry, and generates interior concepts that respect your real walls.

Turning a floor plan into a finished-looking room used to mean hiring a designer or wrestling with CAD software. AI has collapsed that into minutes, but only if the AI actually understands your space. Here is how Kansumi goes from a flat drawing to interior concepts you can trust.
The result looks like a photorealistic, 3D-style render of your room, while under the hood the geometry stays a validated 2D scene graph, so every image is measurable rather than imagined.
1. Read the plan
You upload a phone photo of a sketch, a scanned blueprint, or a PDF. Kansumi's vision model extracts the geometry: walls as line segments, doors and windows as openings on those walls, and any dimension labels written on the drawing. Everything is stored as a structured scene (not a picture) so later steps reason about real coordinates, not pixels.
2. Confirm one real dimension
AI extraction is fast but never perfectly certain, so Kansumi shows you the detected layout over your original image and asks you to confirm a single real measurement (say, a 4.2 m wall). That one confirmation calibrates the entire scene to true scale. It is the difference between a render that looks plausible and one that is actually built on your dimensions.
3. Generate concepts from the scene, not a guess
Only after the geometry is validated does Kansumi generate interior concepts. Crucially, the prompt is derived from the scene graph (wall positions, room type, openings) so the renders match your layout instead of inventing extra windows or doors. You get several distinct styles to compare side by side.
4. Refine in plain language
Ask the assistant to move furniture, swap a style, or check whether a king bed fits. Spatial edits update the layout; appearance edits restyle the selected concept. Every change traces back to the same validated scene.
The result: interior design that starts from your space, with honest confidence scoring at every step. Try it free with your own floor plan.
