Describe the house. Walk through it.
Say what you want — "two-storey house, four bedrooms, garage under the west wing" — and Archiagent designs it as a building: storeys that stack, walls with thickness, a roof with a real pitch. Then you walk through it in the browser.
Most "AI home design" tools produce a pretty picture of a house that could not be built. Archiagent produces the house: every storey has a floor level, every wall has a thickness, every roof has a pitch and an eave. You can measure it, change it, and stand inside it.
Floor levels, slab thicknesses and stairs that land where they should. Change the ground floor and the floor above follows.
7 roof types and parametric columns. Curved walls where you want them, straight ones where you do not.
9 door types and 10 window types, each with a hinge side and a swing, so circulation is checkable rather than decorative.
The 2D plan, the 3D building and the final render are the same object. Nothing is re-drawn between stages, so nothing drifts.
A house design is a hundred small decisions, and most of them change twice. You make each one in a sentence and keep everything you already settled.
Each instruction is an edit to the building, not a fresh generation. The version you liked does not disappear because you asked for one more room.
Storeys, rooms, rough area, which way the garden faces. Plain sentences — no CAD vocabulary required.
Every floor is laid out in scaled 2D before anything goes vertical, because a house that fails in plan fails in 3D too.
Walls extrude, the roof is fitted, openings are cut, stairs connect the levels. In the browser, with no GPU of your own.
First-person walk mode at 1.6 m. Furnish each room, then take any view to an 8K render from the same canvas.
Test the house you have been sketching on paper — in metres, with a roof that behaves, before an architect quotes you for the first draft.
Put ten massing options in front of a client in an afternoon, then take the one that survives into your own workflow.
Turn a site brief into buildable-looking volumes fast, and show a unit in 3D long before there is anything to photograph.
Model the extension, the loft conversion or the removed wall, and see what it does to the floor above before committing.
It can design a house you can inspect and change. Archiagent works on real geometry — storey heights, wall thicknesses, roof pitches — rather than on an image of a house, so the output can be measured and edited instead of only admired. It is a design tool, not a substitute for the architect and engineer who sign off on a building.
Yes — multi-storey is the normal case, not a special mode. Slabs, stair openings and floor-to-floor heights are handled as part of the model, and a change on one level is re-checked against the levels above and below it.
No. You describe the house in ordinary language and edit it the same way. Everything runs in the browser — there is nothing to install and no GPU requirement on your side.
There are 7 roof types with real pitch, overhang and eaves. Ask for hipped instead of gabled and the roof is rebuilt against the same walls, with openings re-placed where the new geometry allows them.
They are scaled, dimensioned and consistent, which makes them a serious starting point for a builder or an architect. They are not stamped construction documents — local codes, structure and services still need a qualified professional.
Yes, and without exporting anything. The same model gets furnished room by room against real clearances, and any view of it can be rendered up to 8K from the same canvas.
