Sweet Home 3D is a free, open-source and cross-platform (written in Java) interior aided design software from France. It can help you design and decorate your furniture on a 2D house plan, and allows to preview the whole panorama of the decoration layout with 3D perspective.

If have a ready room plan on hand, you can import it into the Sweet Home 3D as the background, after setting the proportion, you can directly draw the walls according to the existing content. Meantime, any changes made to the plan will be displayed in the 3D view in real time, in this case you can view the realistic rendering at any time.

AppNee provides the Sweet Home 3D (Microsoft Store Version – including all extra furnitures and textures) multilingual paid full versions (integrated with Java and the latest collection of furniture models & textures) for Windows 32-bit and 64-bit, and Mac.

Sweet Home 3D is available under two versions:

  • A free version available at SourceForge.net that comes with 100 pieces of furniture and 26 textures (version 6.6 – 77.1 MB)
  • A paid version available on the Amazon App Store bundled with 1500 pieces of furniture and 418 textures (version 6.6.1 – 229 MB)

// Tips //

  • To cover a surface with a texture that repeats itself like a wall pattern, prefer choosing a seamless texture
  • To avoid reducing Sweet Home 3D performances, do not import images with a large resolution (generally, 256 x 256 pixels images already give good results). If you have to reduce the resolution of an image, you should prefer a better JPEG quality over a larger resolution
  • If Sweet Home 3D refuses to import some of the ZIP files proposed on these sites, please unzip them first
