Before you start
Prepare your photo of the existing building
Renovation clients need to see their own building changed, not a generic example. Photograph the existing facade or room, say what stays and what changes, and RenderChat edits the photo into the proposal you discuss with them.
Pick even light
Overcast light avoids hard shadows that the AI would have to work around.
Separate keep from change
List what must stay — roofline, neighbours, openings — and then what changes.

Refine in chat

Example briefs
Renovation briefs to start from
Copy a brief, paste it into RenderChat with your photo of the existing building, and change the materials and mood to match your project.
Renovate this facade. Replace the beige render with white glazed brick, fit black steel windows in the existing openings, add a timber entrance canopy. Keep the roofline, the neighbouring buildings and the street unchanged.
Renovate this room in the photo. Keep the walls, windows and ceiling. Replace the carpet with wide oak boards, paint the walls warm white, add built-in shelving on the left wall and linen curtains.
Nano Banana 2.1 in RenderChat
Working with Nano Banana 2.1
Google's Nano Banana 2.1 Gemini image model. RenderChat runs it as a native conversation, keeping your model view, references and follow-ups in one thread.
- Attach material and mood references in the same message as your model view.
- Draft at 1K while you settle the direction, then re-run the chosen version at 2K or 4K.
Quality check
What to check before you share it
- Neighbouring buildings and the street — they should be untouched.
- Window positions: an update should reuse existing openings unless you asked otherwise.
- Perspective lines staying consistent with the original photo.
