When a building is so complete within itself, I always think, "Why do I even have to go inside it?" I would love to do architecture that people can have a free hand in the making of it. We've done spaces where things are hinged and they can go out or in, but that's not freedom. That's supermarket freedom, or the notion that you can have anything you want as long as the supermarket carries it. We would love to do a space where you go inside and there's nothing there. You might have a seat and when you don't need it anymore you get up and it disappears.

Sustainability has become a religion in architecture - not that there's anything wrong with it - but I think it has to work both ways. Everyone thinks architecture has to be subservient to sustainability, but what if we thought in the other direction, like, what can sustainability do to make architecture more exciting?

I like Richard Serra sculptures too but I wish they had a goddamn hot dog stand inside.

Maybe I can pull at my breast in a kind of futile attempt to develop a woman's breast. It's not that simple to become a woman. But I think what was important, when I think back on that work, is something like The Little Engine That Could. It's me saying, I think I can, I think I can. Though I'm doing something I obviously can't, it's the process toward it that is important. The will toward it, the effort . . . My work was about getting to a place that you couldn't get to.

Public space can be a lot better with some private space to contradict it and vice versa. It keeps the system alive. If the system is just one thing, then it's closed and it eventually dies.

Modernism was a big thing for me, coming from a father who was very interested in art, music and culture - and almost always Italian art, music and culture. One good thing about Italians is that culture is part of everyday life. But Modernism is a movement of the past. The idea of a Modernist building as a sculpture set on a pedestal of grass is a part of Modernism that I'm not so crazy about.

You could walk around behind the typist and read the text, which was about hearing, and what you heard was the sound of the typewriter. Of course, this was a pre-electric typewriter, a typewriter that made noise.
