What Space Designer 3D is

Space Designer 3D is browser-based software for drawing 2D floor plans, furnishing spaces, and viewing designs in real-time 3D. As users draw, room areas, wall lengths, and total floor surface update live. The product includes thousands of furniture items, fixtures, and decor, plus a real-time material editor. The site says users can generate HD and 8K photorealistic images from floor plans. Drawing floor plans and modeling in 3D are always free, while renders and AI-enhanced images consume credits. The free Starter plan includes one project, a limited catalog, PNG, JPG, and PDF exports, and 10 rendering credits. Premium costs $25.00 per month and includes 25 projects, full catalog access, DXF exports, and 20 monthly credits; Ultimate costs $45.00 per month and includes unlimited projects, a pro catalog, specified imports, and 40 monthly credits. Business and Business Pro are billed yearly at €6,000/year and €12,500/year, respectively. Space Designer 3D was founded in 2010, and Asynth is the independent software company behind it. The browser product requires no download or installation.
