3D House Planner

3D House Planner is a free web app for designing houses and apartments. Draw the floor plan in 2D, see it live in 3D, furnish it from a large catalog and walk through it in first person. No installation and no account needed. Export: IFC (IFC4) for BIM workflows, DXF and SVG for CAD, OBJ, GLB and STL for 3D modeling and 3D printing, and PNG for presentations. Free for personal and commercial use, with no watermark. AI studio: optional AI rendering tools turn the exact camera view of your 3D model into photorealistic renders: restyle a room, turn a sketch into a render, or visualize exteriors and gardens. The AI runs on your own Puter account, so the planner stays free. It also includes a glTF material editor and home finance calculators, and is available in 10 languages.
