Open a real house
Start from the 140-design catalogue — a gable with an attic today, a flat-roof two-storey tomorrow. The app opens on a different house each visit, and everything stays editable once placed.
Use case
Draw it.Walk it. Understand it.
Teach architecture and construction in a browser tab. Students draw walls, cut real openings, fit roofs and light rooms with the real sun — then walk through what they drew, first person. Free to start, nothing to install on the school's machines.
The class loop
A lesson, in four moves.
Draw and cut
Students draw walls on the plan and cut windows and doors as real booleans — rectangle, circle, triangle. The wall graph handles junctions and mitred corners; rooms compute themselves from the plan.
Light it with the real sun
Pick a place and a date. The shadows are the ones the building would really cast on that plot, that day — orientation stops being an abstraction on a slide.
Walk it and share it
One link per class: everyone opens the same design, walks through it in first person and talks it over in the room thread. The critique happens inside the building.
Why it fits teaching
Free to start, runs on what schools have.
Free to start
Open any of the 140 houses, orbit, walk, play the sun. The free plan covers the whole classroom — no card, no install, no license server.
A tab, not a lab rebuild
Three.js on WebGL2 in the browser the school already owns. No install, no plugin, nothing for IT to babysit.
The catalogue is teaching material
Single storey, attic, two storey; gable, hip, flat, shed roofs; none, one or two garage bays — 140 ready designs students take apart and redraw.
Editing is one switch
Editing is off when the page opens — a design shared for looking looks the same to every student. Armed by the Design door or B when it's time to build.
The critique happens inside
They drew it. Now they walk it.
Walk mode turns the plan into a place: WASD down the corridor they drew, E opens the door they cut, Shift runs to the window they placed. The plan stops being a drawing and becomes a building.
Open the designerFor institutions, too.
- One link per class — students open the same design, no files, no USB sticks
- Editor shares carry areas: hand the class just the garden, or just the inside
- The room thread keeps the critique with the building, not in a chat app
- Designs save as *.webhome.json — coursework that opens anywhere, on any machine
- The reveal builds the house piece by piece on load — foundation, walls, windows, roof
Teach the building,
not the software.
Free to start — open a house, orbit it, walk it, on the school's own machines.
