Free floor plan maker widget for your site

Writing about ADUs, building them or selling homes with room for one? Put a working floor plan maker on your page. Visitors pick the size and rooms, see a measured layout and download it as a CAD file, without leaving your site.

Type and size controls: detached cottage, attached unit, garage conversion or junior ADU, 300 to 1,200 sq ft, studio to 3 bedrooms.
A measured 2D layout that redraws as visitors change anything, with every room's width and depth.
A free DXF (CAD) download of the layout, built in the visitor's browser. No signup, no ads.
Every drawing is a concept layout: a licensed designer finalizes the plan a city approves.
