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

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.

The architecture profession has lost a lot of its integrity, especially in the USA. The general architect here has no scruples, no ambitions.

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.

Chinese buildings are like American buildings, with big footprints. People don't care about daylight or fresh air.

You don't know what the Chinese expect in the way of beauty. The presentation is just a farce. You come into a room filled with 50 people and they don't talk to you. There's very little interaction.

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.
