Frequently Asked Questions about 3d House Planner

Can I import my own 3D models into 3D House Planner?

Yes. The tool supports GLB, GLTF, OBJ, and Babylon file formats, so you can bring in models you've created elsewhere or downloaded and customize them within your design. You can also export your finished work in these same formats.

Does 3D House Planner save my designs to the cloud?

No. All designs stay local to your browser with no cloud storage or data collection, which means your floor plans and room layouts remain fully private. You're responsible for saving or exporting your work when you want to keep it.

Can the AI generate a floor plan from a photo of an existing room or sketch?

Yes. 3D House Planner includes an AI floor plan generator that can create a 3D layout from images, which is useful if you're starting from a photograph or rough sketch rather than building from scratch. You can then edit and refine the generated plan using the sketching tools.

What happens if my design is very complex, does 3D House Planner support multi-story buildings?

The tool supports up to 50 floors, so you can design multi-story homes and apartments. There are no stated limits on how large or detailed a single floor can be, though performance will depend on your browser and device.
