We feel that buildings in general should be connected to the ground, the earth. We think of buildings in terms of heavy and light. There is a notion these days that architecture is increasingly becoming lighter. But I don't believe it one bit. It's just an illusion of lightness.
Buildings are heavy.
I haven't met a building I could lift. The pool itself is excavated from a hillside. The materials are certainly about durability. But when you look up toward the ceiling, there is that very intense color and the oculus with light coming in, so you get a sort of flight. It's both roots and wings.
