This page will host the parametric floorplan of the house interior — every room as a measured, wall-and-door-aware 3D model.
Captured with 3D Scanner App (free) using Apple RoomPlan API directly on iPhone 16 Pro. Output: USDZ 3D model + parametric room JSON. WiFi planning, future remodels, and any other "where in the house" question runs from this file.
To do the scan yourself, see scan instructions.
