I'm a do-gooder liberal.

If I knew where I was going, I wouldn't do it. When I can predict or plan it, I don't do it.

On certain projects, on big public projects, people definitely are interested in making them greener, but on smaller projects with tight budgets it can be harder.

I don't micromanage the interiors. People ask me to and I say no. I don't want to control everything.

Artists dismiss me as an architect, so I'm not in their box, and architects dismiss me as an artist, so I'm not in their box.

You've got to like the people you work with.

You have freedom, so you have to make choices - and at the point when I make a choice, the building starts to look like a Frank Gehry building. It's a signature.
