And it still had that quality of movement when you looked back and looked around.

And I made that out of a wooden frame and covered it with metal.

And I took that language into the buildings.

Okay, here's how you do it.

I do maybe 50 models.

They look, sometimes they look like crumpled paper, so people think I crumple up paper and that's how they get there.

And I analyze the shapes as though they're structures with the computer to determine whether I'm within the budgetary constraints.

And over time, I slowly evolve these shapes and refine them.

I thought if I could make it one piece, that I would have a lot of flexibility.

And there's a tradition, and there's a detailing tradition, and there's a performance tradition so that you can rely on it not to leak, not to get you in trouble if you follow the rules of it.

I started making the whole building.

I started to take the roofing material down and make the walls part of the roofing material.
