If you're serious about being an architect, you've got to learn how to take responsibility. It's not fluff. You have to do every detail on every bloody piece of the building. You have to know how the engineering works. You have to know how the fittings go together. You have to master the mechanical, electrical, acoustical - everything.

The rap on me on the street is the opposite - I'm impractical, I'm more expensive, it's too complicated and I run over budgets, which isn't true. None of that's true and there's plenty of documentation if anybody needs it.

When people condemn me for designing iconic buildings in cities and not having an idea what a city is, they haven't done their homework. I started in urban design and city planning. It's just that when I got out of school there wasn't much of a market for that. There still isn't.

Art is about people. I think the discussion about whether architecture is art or not is lamebrain.

There's a drive in us to express ourselves in some way or form. We pick up whatever material is available. It's primitive. Kids see sand on the beach, build something and show their parents: "Look what I did, Mama." It's necessary to us.

Everybody's an artist. Unfortunately we don't treat them as such.

The fact is I'm an opportunist. I'll take materials around me, materials on my table, and work with them as I'm searching for an idea that works.
