Just put the home you want into words. AI designs it on the spot — building-code checks, auto-generated permit paperwork and a visualized permit-readiness score, all in one browser.
Unlike desktop BIM software, it runs in just a browser — no login, no fees — and carries you from design to permit preparation.
Building-coverage, floor-area-ratio, setback, daylight and ventilation are checked automatically, and your current permit-readiness is shown as a score. Export permit.xml / webpro.xml / structural PDF. The final filing is done together with a partner licensed architect.
"Add a 10 sqm room on the 2nd floor", "widen the south window to 1.8m" — instructions chain tools, streaming. External AIs can also run catalog search, home creation and code checks via MCP.
No signup. Three.js viewer, editing and IFC4 / DXF / STL export are all free. Published BIM data is reusable under MIT.
Permit-data completeness for the three homes we actually operate — measured, not invented.
Score = how complete the data is toward permit grade. The final filing is always done with a partner licensed architect.
Click to launch the 3D viewer, JSON editor and permit validator instantly. We publish homes that passed code and structural checks.
A home is a vessel for the will of its era.
bim.house keeps the homes you make in a form that can be safely handed down a century from now.
