It's my goal to make a building as immaterial as possible. Architecture is a very material thing. It takes a lot of resources, so why not eliminate what you don't need as long as you're able to achieve the same result?

Every building is a prototype. No two are alike.

We prefer synthetic rather than natural materials. Natural products are almost too valuable. Wood is much harder to produce than metal. And metal is recyclable, while wood isn't.

A good engineer thinks in reverse and asks himself about the stylistic consequences of the components and systems he proposes.

Critics are entitled to have an opinion, but how can they judge how comfortable a building is? No critic is smart enough to judge how a building will perform over time.

When I came to America in the '60s, it was the place to be. I wonder if I'd come here today.

I strive for an architecture from which nothing can be taken away.
