Built a Room-by-Room 3D Home Design Webapp with Claude Cowork in Under an Hour

Michael Saif Scottsdale Arizona · 1H AGO

I built this webapp for a friend who is building a house. It lets you see the finished version of every room in the planned home before anything is built. I described the idea to Claude Cowork, had a short back-and-forth and answered its questions, and it built the app in four stages. 1. Upload one or more floor plans. You can add as many as you need. 2. Select a room from the floor plan. The app shows it in several 3D views that you can rotate. 3. Ask for the room the way you want it when completed. For example: "Show me with a dark colored wood floor with blue walls" 4. Make changes and ask again, such as light colored wood floors. 5. Ask the app to add furniture so you can see how the room will look when finished. 6. Save multiple designs for each room, and export any image as a PNG. The whole build took less than an hour from start to finish. I can share the finished prompt if anyone wants to build something similar.
