Free open-source app to draw home floor plans, furnish them with 3D furniture models, and view the result in 3D; aimed at homeowners and hobbyists
Why we recommend it
Sweet Home 3D is the most approachable free path from floor plan to furnished 3D view, and it runs everywhere. The dated Java UI and modest rendering quality are the price you pay for a tool that has been free and open for two decades.
Strengths
- Free open-source desktop app (GPL) for Windows, macOS, Linux, iOS, and Android, with installers that bundle their own Java runtime
- Imports 3D models in OBJ, DAE, and 3DS formats (supported since v1.6) and includes built-in photo and video rendering
Drawbacks
- Java-based desktop app with a dated interface; the plain JAR version defaults to a 96 MB memory limit the FAQ says is too small for middle-sized homes
- Built-in rendering quality and speed fall short of photorealistic renderers, and performance degrades on large, furniture-heavy plans per user forum reports
