Reading his books changed the way I'm looking at houses and apartments. Not from outside, but the layout. I guess (some of) the patterns are quite obvious, but as usual, it helps when somebody points them out. Two example things that stuck to me:
1) Intimacy gradient: Public areas where you host guests, meet people and closer to the front door. The deeper you go, the more private it gets.
2) Parents and children's realms: Separate areas for parents and kids, common area that connect them.
When shopping for apartment and browsing through many different layouts, this kind of simple things help rule out many of them.
