The guest house is made from pieces that are connected together to form the whole building. You can see them most clearly at the edges, where the individual planes stretch out (top illustration).
I will try to restrict my comments to this one building. Schindler’s buildings can be very different. These comments are how I see the building, you may see it differently. I will try to keep my comments short.
The McAlmon House was built in 1935 in Los Angeles. It is one of Schindler’s better known houses. He moved an existing bungalow down the hill to the front of the lot. He added a living room and garages to it and wrapped it up in his sculptural forms. This became the guest house. The new main house, designed in the same vocabulary of forms, was put towards the back of the lot-at the top of the hill with wonderful views to the northeast.
