Shoot it straight
Photograph from the height you would show the client, with verticals level and the whole facade or room in frame.
ByteDance · Seedream 5.0 × Renovation
Visualize renovations on a photo of the existing building with Seedream 5.0 in RenderChat. Upload your photo of the existing building, describe what you want, and refine the render in chat.


Drag to compare the photo of the existing building with the Seedream 5.0 render. Input is an AI-generated example.
Before you start
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.
Photograph from the height you would show the client, with verticals level and the whole facade or room in frame.
Overcast light avoids hard shadows that the AI would have to work around.
List what must stay — roofline, neighbours, openings — and then what changes.
How it works
by ByteDance
Shoot it straight, pick even light and separate keep from change. The checklist above has the details.
The start button on this page opens a new chat with Seedream 5.0 Pro selected. You can also pick it from the model menu in the composer.
Attach the image and say what must stay, then the materials, light, setting and people. Start from an example brief below.
Ask for changes in follow-up messages. Each Seedream 5.0 request is sent fresh from your latest image, so repeat the constraints that matter.
Download the image at the resolution you chose (1K · 2K).
Example briefs
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.
