Rule of thumbMandatory
No habitable room is a corridor
CIR-PASSTHROUGH-01Description
No room may require passing through a bedroom or bathroom to reach another room.
Why this exists
A bedroom or living room you have to walk through to reach another room is a hallway pretending to be a destination. Circulation must route around habitable rooms, not through them.
