HZplan turns floor-plan images or written dimensions into structured, editable home plans your assistant can reason about. Users can create and refine multi-storey layouts with floor-specific rooms, walls, doors, windows, furniture, and surface finishes; import and calibrate floor-plan images; inspect dimensions and topology; add notes and custom attributes; make targeted geometry edits; create materials from reference images; generate 3D object models; and export storeys as PNG or SVG.
