Livability check
No problems- !Living room has light from only one direction; two-sided light reads far better. (Light on two sides of key rooms)
- !Living room renders 2.0:1 in this layout — narrower than the ~1.7:1 ideal. (Habitable rooms not corridor-like)
- !A door into Entry has only 1.3 ft to swing — tight for a 3.0 ft door. (Door swings don't collide)
- !A door into Entry has only 1.3 ft to swing — tight for a 2.7 ft door. (Door swings don't collide)
- !A door into Hallway has only 2.1 ft to swing — tight for a 2.7 ft door. (Door swings don't collide)
- !A door into Hallway has only 2.1 ft to swing — tight for a 2.7 ft door. (Door swings don't collide)
- !A door into Hallway has only 2.1 ft to swing — tight for a 2.5 ft door. (Door swings don't collide)
These are architect rules of thumb the building code doesn't cover — room reachability, proportion, daylight, and adjacency. Warnings are nudges, not failures. Sourced from A Pattern Language, NKBA, and practitioner conventions.
