For various reasons (touring Schindlers, interviews, general wondering...), I've been pondering the design of our house. Inside, the house is amazingly efficient. It's so easy to move through it. When we give a friend a tour, it's like "Whelp, there it is. That was fast, wasn't it?!?!!" On the other hand, the outside appears complex: There's a lot of articulation and volumes somewhat protruding from the house.
The other night, while thinking it over, it occurred to me why: The floor plan is organized about a perfect "L". Every room, space, or entry is accessed from this "L". The rooms that protrude from the "L" are the sizes needed to meet their purpose, with some (but really not a lot) of alignment and "squaring of space" to meet some aesthetic and construction purposes.
Pretty simple, right? This differs from what Schindler did in that he intersected volumes into each other. Here, the volumes protrude from "access corridors".
