In an ideal world, pressure should come from below and from the top.

People live and work in uninspiring environments, but look inside those rooms. Look at the painted walls and the decorations. People rebel even in the most controlled office environment in which they're not allowed to do anything. You see the little bulletin board in front of a person's desk with their photos, clippings, cartoons and whatever else.

You can't ignore history; you can't escape it even if you want to. You might as well know where you come from, and you might as well know that everything has been done in some shape or form.

I'm inspired by a lot of stuff. I always was interested in sculpture and painting and music and literature and all those things. There's no one thing.

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 work from the inside out.

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.
