About Space Designer 3D

Floor plans are drawn in two dimensions and then walked through in 3D with Space Designer 3D, an online interior design tool that needs only a browser, with no installation. Its site says people have used it since 2010, and that the audience now runs to millions.

Three steps from sketch to walkthrough

The process is laid out in three steps. Users draw walls and add doors and windows, much as they would sketch on paper. They then furnish each room from a large catalog of furniture items and materials. Finally they walk through the space in real-time 3D.

Renders and measurements

The tool produces HD and 8K photorealistic renders, where AI helps choose lighting, materials and camera angles. Room areas, wall lengths and total floor surface update live while drawing, and the 2D and 3D views stay in sync so the numbers match. Plans export as PDF or DXF files.

Who uses it

Its audience, as the site lists it, runs from homeowners to estate agents, home builders, office planners, furniture retailers, students and teachers, and design and architecture teams. Its output suits interior design presentations, home visualizations and property listings.

A gallery of 3D projects drawn in the application shows examples, including an office building.
