About
Sweet Home 3D is a powerful yet accessible interior design application distributed under the GNU General Public License. It enables users to create accurate 2D floor plans by drawing walls, doors, and windows, then instantly switch to a 3D view to explore and decorate their space. The software ships with over 10,000 pre-built 3D furniture and object models, along with more than 400 textures, covering every room and style imaginable. Users can arrange and customize furniture, apply wall colors and flooring, adjust lighting, and generate high-quality 3D photo and video renderings — all within a single application. The interface is designed to be intuitive and requires no prior design experience, making it equally suitable for homeowners planning a renovation, interior decorators prototyping layouts, and architecture students learning spatial design. Sweet Home 3D is available for download on Windows, macOS, and Linux desktops, as well as iOS and Android mobile devices. It can also be used entirely online through any WebGL-compatible browser with no installation required. The project is actively maintained, available in 29 languages, and supported by a community of contributors on SourceForge. Plugins and tools extend its capabilities further for power users.
