3D House Planner is a professional, free-to-use web application designed for comprehensive 3D home and apartment design. Accessible directly through your browser, it requires no installation or login, ensuring user privacy by saving all projects locally. The platform empowers users to build detailed architectural models with ease, from initial sketches to photo-realistic visualizations.
A standout feature is its integrated AI design assistant, which allows users to generate room layouts, house structures, or furniture arrangements simply by describing their vision or importing existing plans/photos. This AI works with the same editable tools as the user, ensuring flexibility. The software boasts a live 2D ⇄ 3D synchronization, meaning any change made in one view is instantly reflected in the other, streamlining the design process.
For visualization, 3D House Planner offers multiple rendering modes, from a light draft for basic laptops to an "Ultra" mode with advanced effects like soft shadows, ambient occlusion, and reflections, alongside AI photo generation. It supports Building Information Modeling (BIM) by assigning IFC classes and properties to every element, enabling quantity take-offs, cost estimates, and seamless file exchange with other BIM/CAD tools.
Users can import and export a wide array of formats, including IFC, DXF, GLB, glTF, OBJ, STL, SVG, PNG, CSV, and JSON, making it highly interoperable. The platform provides a vast catalog of thousands of objects and textures for furnishing and decorating, along with tools for terrain modeling and painting. It supports designing up to 50 floors per project.
Beyond the main 3D editor, 3D House Planner offers additional free tools: a dedicated 2D Planner for drawing floor plans, a Material Editor for customizing 3D model appearances, and an AI Rendering tool to transform sketches into high-quality renders. The application is completely free for both personal and commercial use, emphasizing data privacy by not collecting design data and storing projects exclusively in the user's browser. This makes it an ideal solution for architects, interior designers, and homeowners looking for a powerful, accessible, and private design tool.
