Interior material replacement
AI interior design with a clear material brief.
Start with your room photograph and identify the surface you want to change. Keep wall finishes, flooring, cabinetry and color references separate from the room layout.
Open this workflowAI generation, saving and collaboration are available. Choose Seedream, Nano Banana or GPT Image in Generate. Krea’s official model is not connected.

What to bring
Give each reference one job.
A material sample with scale, texture and finish notes.
A restrained color palette or lighting direction.
A ready-to-edit starting point
Your workflow brief.
This brief opens with the reference board. Adjust it for your actual images and intended output.
Interior material brief: keep the room geometry, windows, doors and furniture positions. Change only the named surface using the material reference. Record the intended finish, scale, grain direction and color temperature.
Use this brief in the editor ↗Define the surface before choosing a finish
“Make this room warmer” is a useful mood but an incomplete material instruction. Name the exact surface: the wall behind the sofa, the kitchen cabinet fronts or the floor. Record what must remain unchanged, including doors, windows, furniture and the room perspective.
- Use the original room photo as the layout reference.
- List the surface to change and the features to retain.
- Keep different camera angles on separate boards when possible.
Collect material information beyond a color chip
Wood grain, stone veining, tile scale and gloss affect how a surface reads. A close-up sample can show texture but hide its real size. Add notes about dimensions and direction, then compare it with a wider reference that shows the material in a room.
- Record tile dimensions or plank width alongside the sample.
- Specify matte, satin or gloss rather than leaving finish ambiguous.
- Check a palette under the room’s existing lighting conditions.
Use a board to compare decisions before rendering
Add the room photograph and a material sample as separate references, then name the wall, floor or cabinet surface to change in Generate. Seedream 5 Pro or Nano Banana can create a visual variation. It does not enforce a precise mask boundary, so compare windows, furniture and perspective against the original before treating the image as a design option.
- Keep one baseline room image visible in every option.
- Use text layers for material names and decision notes.
- Export a presentation board rather than presenting a manual collage as a completed AI renovation.
Workflow questions
Interior materials questions
Can I automatically replace a wall or floor here?
Yes. Use the room photo and material sample in Generate and describe the surface to change. This is prompt-led editing with Seedream 5 Pro or Nano Banana; precise masked surface protection is not available and the result needs layout review.
Will the original room layout be preserved?
The original photograph stays saved in your project. Generated edits may change geometry, so compare each result with that source; precise mask protection is unavailable.
Can a design board confirm construction suitability?
No. Material specification, measurements and installation decisions need their own professional review.
