What Is Sweet Home 3D?
Sweet Home 3D is a free interior design software tool developed by Space Mushrooms (formerly eTeks) that lets users draw 2D floor plans and view them in 3D. First released in 2006, it runs on Windows, Mac, and Linux platforms. The application is distributed under the GNU General Public License, making it a truly open-source virtual home design tool.
What Does Sweet Home 3D Do?
This free architectural floor plan software lets you build a digital version of your living space. If you are moving into a new apartment, you can recreate the exact room dimensions and test if your current couch will fit against the far wall.
You might also use it for a kitchen remodel to see how different cabinet colors look under photorealistic rendering. The software automatically translates every 2D wall you draw into a 3D model. You drag items from the built-in furniture catalog and drop them onto your floor plan to see exactly how they look in real time.
