Sweet Home 3D is a free interior design application that helps you draw floor plans and arrange furniture within a 3D representation of your home. Available for Windows, macOS, and Linux, the software makes interior design accessible to homeowners and professionals alike.
The 2D floor plan view enables drawing walls, rooms, and dimensions using simple click-and-drag operations. Doors and windows snap to walls automatically with proper positioning. Dimension annotations display measurements in metric or imperial units. Multiple floors create complete building plans.
The furniture catalog includes over 1,200 3D models organized by categories including living room, bedroom, kitchen, bathroom, and outdoor. Drag furniture from the catalog onto floor plans with automatic floor alignment. Furniture rotates, scales, and elevates for precise positioning.
The 3D view renders your design in real-time, updating as you make changes. Navigate through rooms using aerial or virtual visit viewpoints. Lighting affects how spaces appear with adjustable sun position for time-of-day simulation.
Photo-realistic rendering creates high-quality images for visualization. Adjustable quality settings balance rendering time and image quality. Video creation tours through designs automatically, showcasing spaces dynamically.
Import additional furniture models in OBJ, DAE, and 3DS formats. Export plans to PDF, SVG, and image formats. The plugin system adds features including advanced rendering, measurement tools, and cloud synchronization. Blueprint wallpaper imports scanned plans as drawing guides.
