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.

Prepare your photo of the existing building
Shoot it straight, pick even light and separate keep from change. The checklist above has the details.
Open RenderChat with GPT Image 2.5
The start button on this page opens a new chat with GPT Image 2.5 Sunburst selected. You can also pick it from the model menu in the composer.
Upload and write the brief
Attach the image and say what must stay, then the materials, light, setting and people. Start from an example brief below.
Refine in chat
Ask for changes in follow-up messages. GPT Image 2.5 continues the same conversation, so a short instruction such as "warmer light, keep everything else" is enough.
Download the render
Download the image at the resolution you chose (1K).
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.
GPT Image 2.5 in RenderChat
Working with GPT Image 2.5
OpenAI's GPT Image 2.5, offered in RenderChat as two variants, Sunburst and Flare. Both run as native conversations, so every follow-up message keeps working on the same image thread. Sunburst is RenderChat's default model.
- Start with Sunburst. Switch to Flare in the model menu when you want a second read of the same brief.
- Write follow-ups as edits ("keep everything, warm the light") rather than restating the whole brief.
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.
