Free plan, always. Upgrade when you need DXF and DWG.

Everything your floor plan needs, from prompt to export

Residential layout: Describe your requirements in plain language. Get a complete, constraint-aware floor plan in seconds.
Structure and MEP, across floors: Beam and column grids, plus plumbing, electrical and mechanical layouts, computed automatically and kept consistent floor to floor.
Light and ventilation: Bedrooms, living rooms, kitchens and baths are checked for an exterior wall long enough to take a window, following NBC light and ventilation rules.
Metres or feet: Give sizes in either unit and the plan answers in the same one.
DXF, DWG, PNG and GLB: CAD files ready to open in AutoCAD or Revit, images to share, and a full 3D model. No conversion or cleanup required.

Generate it. Edit it. Walk through it.

Every plan Kozo draws comes with an editor, a 3D studio and MEP layers. No extra software, no redrawing.

Change anything in the editor, by hand, to the millimetre.

Open any plan Kozo draws in a CAD accurate editor beside the chat. Pull a wall and both rooms resize. Add, draw, split or swap rooms. Place doors, windows and furniture, and type exact sizes in metres or feet.

Every tool in the editor

Walk through it in the 3D Studio before a single brick is laid.

Every plan opens as a lit, furnished 3D model right in the browser. Orbit it, look down on it, stand in front of it or walk inside. Change floors, paint, furniture and the sun, then export.

Everything the 3D Studio does

Loading 3D model

Plumbing, electrical and mechanical, drawn in.

Kozo lays services over the plan it draws, on their own CAD layers so you can switch each discipline on or off. It follows the rooms: wet walls where kitchens and baths meet, lights spaced to the ceiling height, fans sized to the room.

Plumbing: wet walls and stacks lined up floor to floor
Electrical: sockets, switches, lights and the distribution board
Mechanical: ceiling fans, AC indoor units and exhaust fans
Every discipline on its own layer in DXF and DWG
