How to Turn a Sketch into a Photorealistic Interior Render with Claude
Turn a Sketch into a Photorealistic Interior Render with Claude and ToolRouter. Convert rough drawings into photorealistic interior visuals during the concept phase.
Tool
Claude is ideal when sketch-to-render is part of a design conversation. You can share the sketch, get a render, discuss what is working, and iterate quickly — exactly the kind of back-and-forth that happens in a real design consultation.

Steps
Once connected (see setup above), use the Interior Design tool:
- Share your sketch and describe the materials, style, and atmosphere you want — for example, 'Japandi with warm timber, natural stone, and low furniture'.
- Ask Claude to run `sketch_to_render` via the interior-design tool.
- Review the render and ask Claude what it interpreted from the sketch and where it made assumptions.
- Refine by specifying overrides — different flooring, window placement, or furniture scale.
- Save the final render to use as a client presentation asset.
Example Prompt
Try this with Claude using the Interior Design tool
Use interior-design with sketch_to_render to turn this rough hand-drawn kitchen layout into a photorealistic render. Interpret the sketch in a contemporary style with dark cabinetry, stone worktops, and warm lighting. Tell me what you assumed and what I should refine.
Tips
- Label key elements on the sketch — island, window, door — so the model interprets the layout correctly.
- Ask Claude to explain where it made assumptions so you can spot misinterpretations early.
- Use the render as a conversation starter with the client, not a final deliverable — the next iteration will be more accurate.
