Bilbao opened in 1997. It was only ten years later that I was asked to do another museum. A lot of other people got work because of Bilbao.

My father probably - he had flashes of creativity - he used to do store windows for fruit stores that he worked in and stuff.

I'm a do-gooder liberal.

I don't know whose box I'm in, and I don't really care.

Look, architecture has a lot of places to hide behind, a lot of excuses. "The client made me do this." "The city made me do this." "Oh, the budget." I don't believe that anymore.

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.

For me, every day is a new thing.
