SpacePlanner

SpacePlanner is a free online floor plan and layout tool that runs entirely in your browser. No signup, no download, no install. Open the editor and start drawing in seconds. Draw walls to real dimensions in 2D and flip to a full 3D model instantly. Every change you make in the plan shows up in 3D immediately, so you can see the space you are designing instead of imagining it. What makes it different: • Indoor and outdoor together. Most planners stop at the walls. SpacePlanner handles gardens, pools, outdoor kitchens, decks and plots on the same plan as your rooms, across multiple levels and basements. • Real construction detail. Parametric catalogs of doors and windows (flush, French, sliding, bifold, sash, arched, round, triangular and more), multi-layer wall build-ups, stairs with automatic stairwell openings, and pitched or flat roofs. • Turn a photo into a plan. Trace over an existing floor plan image, or let AI rebuild it into an editable plan. • CAD-style precision. Object snapping to endpoints, midpoints, centers, intersections and perpendiculars, plus dimension lines you can drag and edit. • Walk through it. Drop into a first-person view and walk the space at human eye level. • Export and share. Compose presentation sheets with title blocks, scale bars and north arrows, then export or share with a link. Built for homeowners planning a renovation, designers mocking up layouts fast, and anyone who needs a real floor plan without learning CAD. Free to use.
