What Sweet Home 3D does
Sweet Home 3D is a free, open-source interior design application distributed under the GNU General Public License and published by Space Mushrooms srl, an Italian private limited company founded in 2021 and headquartered in Milan (Via Melzi d'Eril 29). Built on a Java core, the software lets users draw 2D floor plans with walls, doors, and windows, arrange furniture from a bundled library of 10,000+ 3D models and 400+ textures, and view results in real-time 3D with photo and video rendering produced via SunFlow and YafaRay engines. The product ships in multiple deployment formats — a desktop application for Windows/macOS/Linux, iOS/Android mobile apps, a WebGL browser-based version, and a JavaScript implementation (Sweet Home 3D JS) for web embedding — and is localized into 29 languages.
The offering is complemented by a Plugin Manager and a contributor-developed plugin catalog (e.g., Cabinet Maker, Terrain Generator, Wirings, Electrical Symbols + DXF Export), alongside supporting utilities such as the Furniture Library Editor, Textures Library Editor, and an Exported Homes Manager web service. Sweet Home 3D serves four identifiable user segments: individual homeowners and DIY enthusiasts (primary), professional interior designers and architects, educational institutions, and real estate professionals, with an engaged community forum of 650,770 members and recurring Instagram-hosted design challenges.
The business model relies on voluntary PayPal donations, merchandise, and bespoke commercial licensing for proprietary derivative works; the company explicitly does not display advertising. Sweet Home 3D has no venture capital or private equity funding, no parent company, and no subsidiaries, and operates as a small independent entity. Distribution is multi-channel, spanning direct downloads, five major app stores (Apple, Google Play, Microsoft, Mac App Store, Amazon Appstore), and the SourceForge.net repository.
