I was recently introduced to the work and writing of Japanese architect Sou Fujimoto. One concept that he writes about that I really like is the idea of nest vs. cave.The way Fujimoto describes a cave is that it’s a naturally occurring and pre-existing condition. It is exists independent of humans. So if and when a human decides to occupy a cave, he or she must assimilate their lives to that which is already there. They have to deal with the ambiguity of the spaces because it is not clear how everything should be used.
