It's not the bullet that kills you, it's the hole.

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?

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.

What I never wanted in art - and why I probably didn't belong in art - was that I never wanted viewers. I think the basic condition of art is the viewer: The viewer is here, the art is there. So the viewer is in a position of desire and frustration. There were those Do Not Touch signs in a museum that are saying that the art is more expensive than the people. But I wanted users and a habitat. I don't know if I would have used those words then, but I wanted inhabitants, participants. I wanted an interaction.

What connects architecture and music is that neither one is really an object. It's more like an ambience, a surrounding and a context. You can do other things while you're listening to music and of course, you can do other things while you're in the middle of architecture. The notion of multi-attention seems to me like it's the keynote to the beginning of the 21st century.

Especially once those poetry events began, because, yeah, the stuff was still on the page, but the page was starting to spill into real space, spill into air, once you could hear it, once there was a typewriter, once there was a body of a typist, it was getting rid of the confines of the page.

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.
