You'd never think of taking a cab if you had to walk a mile down Chicago's Michigan Avenue. But in a bad city you take a cab just to go around the corner.

I've never looked at a suburban building as being a minor building and an urban building as being a major building.

I find if my body feels well and I exercise regularly, I think better, work better and feel better.

When I think of some of my earlier work, it really seems a fortunate coincidence that I succeeded.

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

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.

Every building is a prototype. No two are alike.
