The American attitude towards efficiency and execution should always underlie architecture.

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?

For me, drawing generates thinking and vice versa.

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

America has always imported history.

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.

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