3D House Planner

3D House Planner is a completely free, browser-based application that lets you design detailed 3D models of houses and apartments without any software installation. You can build walls, floors, and roofs with intuitive controls, furnish spaces using a catalog of thousands of objects, and apply realistic materials and textures. The tool supports designing up to 50 floors and includes professional features like terrain modeling and Physically Based Rendering for realistic visualizations.

What makes 3D House Planner stand out is its AI-powered floor plan conversion feature — you can upload a 2D floor plan image and generate a 3D model with a single click. The tool supports multiple file formats (GLB, GLTF, OBJ) for importing and exporting your work, and it maintains complete privacy by storing everything locally on your device rather than in the cloud. You can also create videos and snapshots of your designs to share with others.

This tool is particularly valuable for homeowners planning renovations, interior designers creating client presentations, and architecture students learning spatial design. The free commercial use license makes it suitable for professional projects, while the intuitive interface ensures even beginners can start designing quickly. Whether you're remodeling a single room or planning an entire multi-story building, 3D House Planner provides the essential tools without the complexity or cost of professional CAD software.
