GPT Image 2.5 Floor Plan to 3D Render
Turn 2D floor plans into rendered 3D floor plans with GPT Image 2.5 in RenderChat. Upload your floor plan, describe what you want, and refine the render in chat.

Drag to compare the floor plan with the GPT Image 2.5 render. Input is an AI-generated example.
Before you start
Prepare your floor plan
Clients read rendered floor plans far faster than line drawings. Upload a clean 2D plan, list the room uses and finishes, and RenderChat turns it into a top-down 3D floor plan you can adjust room by room.
One unit at a time
Crop to one apartment or floor so the rooms are large enough to read.
List the rooms
Name each room and its floor finish in the brief: oak in the living areas, tiles in the bathroom, and so on.

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
Floor plan to 3D briefs to start from
Copy a brief, paste it into RenderChat with your floor plan, and change the materials and mood to match your project.
Turn this floor plan into a photoreal top-down 3D floor plan with the roof removed. Keep every wall, door and window position. Oak floors in living and bedrooms, light grey tiles in kitchen and bathroom, Scandinavian furniture, soft even daylight.
Using this floor plan, render an eye-level interior view standing at the entrance looking toward the living room windows. Keep the room proportions. Warm minimal style, oak floor, white walls.
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
- Wall positions and openings against the plan — overlay the two images if it matters.
- Door swings and which rooms connect.
- Room proportions; a long room can come back squarer.

FAQ
GPT Image 2.5 Floor plan to 3D questions
Is GPT Image 2.5 available on the free plan?
Yes. GPT Image 2.5 is available on the Free plan as well as Pro.
What resolution does GPT Image 2.5 render at?
GPT Image 2.5 renders at 1K in RenderChat, with auto + 10 fixed ratios.
Can I keep refining a GPT Image 2.5 result in chat?
Yes. GPT Image 2.5 runs as a native conversation in RenderChat, so each follow-up continues from the previous turn. Short edit instructions work well.
How do I select GPT Image 2.5 in RenderChat?
Use the start button on this page — it opens a new chat with GPT Image 2.5 Sunburst selected — or choose it from the model menu in the chat composer.
Can it create an eye-level interior from a plan alone?
Yes, if you describe where the camera stands and what it looks toward. Results from a plan alone are interpretive; a quick 3D view gives more control.
Will the 3D plan be to scale?
It is an illustration, not a measured drawing. Check walls and openings against your plan before using it in a sales or planning document.
