Our verdict: Sweet Home 3D is the easiest free way to plan a room layout or a whole apartment and see it in 3D. Drawing walls and dragging in furniture takes minutes. The free Windows version includes a small furniture catalog, while the larger catalog comes with the paid store version.

About Sweet Home 3D

Sweet Home 3D is developed by eTeks and released under the GNU GPL v2. You draw walls in a 2D plan with precise dimensions, drag doors and windows into them and furnish rooms from a searchable catalog, while a 3D view updates at the same time.

The free Windows installer is distributed through SourceForge, bundles its own copy of Java and includes 100 pieces of furniture and 26 textures. A paid Microsoft Store version adds more than 10,000 models. You can also import free model and texture libraries or your own 3D models.

What it does well

  • 2D floor plans. Straight, round or sloping walls with dimensions, room areas and labels.
  • Live 3D view. Aerial view or a virtual visitor walking through the home.
  • Furniture catalog. Drag furniture into rooms and change size, color and texture.
  • Photo and video renders. Photorealistic images with lights and sunlight by time and location.
  • Import and export. Imports blueprints and 3D models; exports PDF, images, video and 3D files.

Who it is for

Good fit

Homeowners and renters planning a renovation, a move or a new furniture layout.

Look elsewhere

Architects who need construction drawings, BIM data or structural calculations.
