One of today’s highlights was visiting what is called the Art Triangle in the Roppongi section of Tokyo. The smallest museum here is the Design Site project by Tadao Ando. It is a one-story building stretched along the edge of a small urban park, designed by EDAW, with a large commercial complex by SOM on the other side of the park. As one would expect, it is beautifully detailed. The roof appears, and feels, like it is steel, with a waterproof coating, and all of the joints ground smooth. The concrete feels like it has been waxed to a smooth, warm, low-luster sheen. The back of the building is all concrete with an impossibly long horizontal window cut into it.
