These ChatGPT prompts for interior design help homeowners and interior designers plan room layouts, choose colour palettes, brief mood board images, build materials checklists and write client proposals and social posts. Copy a prompt, paste it into ChatGPT (Claude and Gemini work too) and replace the [brackets] with your room, style and needs. Key tip: upload a photo of the room so the ideas fit the space you have.
Interior design is one of the places where ChatGPT surprises people. It won't replace a designer's eye, but it's very good at the thinking around it: asking how a room gets used, turning a vague feeling into a palette, and writing the brief, the checklist and the caption that follow.
I've written these for two groups: homeowners planning their own rooms, and interior designers who'd rather put less time into admin and more into design. ChatGPT can take image input and generate images, so several prompts ask you to upload a photo or create a visual. If you're planning a workspace, my piece on how a thoughtful home office changes the way you work pairs well with them.
Room planning and layout ideas
Give ChatGPT the shape of the room and how you live in it, and the ideas get far more useful.

How to get better answers for your rooms
- Upload a photo. ChatGPT can take image input, so a photo of the real room gives it far more to work with than a description.
- Give measurements and constraints. Room size, ceiling height, where the radiators sit and what you're keeping all change the answer.
- Say who lives there. Children, pets, working from home and how often you host matter more than style words.
- Change one thing at a time. When an image is close, ask for a single change and keep everything else the same.
- Check sizes in real life. Measure before you order. An image is a direction, not a floor plan.
- Keep client details private. Leave out names, addresses and anything personal when you paste notes in.
If you'd like your design team to build prompts like these together, this is how my AI workshops run.
