Space Designer 3D
Space Designer 3D is an online floor plan and 3D design software, built by Asynth, an independent software company founded in 2009 by two architects. It runs entirely in the browser, with nothing to install.
Users draw a 2D floor plan with walls, doors, windows and multiple levels, or import an existing plan as a base. They furnish it from a large catalog of furniture, materials and finishes, explore the project in 3D and create photorealistic renders, enhanced in one click with AI Image Boost. Projects can be exported as images, PDF, DXF and IFC, and shared online.
Homeowners use it to plan a renovation or a new home, architects and interior designers to present concepts to clients, and real estate professionals to show the potential of a property. Companies can also offer the planner to their own customers, branded and on their own domain.
