The back of Saint Peter's is one of the finest pieces of architecture I've ever seen.

There is a backlash against me and everyone who has done buildings that have movement and feeling.

The rap on me on the street is the opposite - I'm impractical, I'm more expensive, it's too complicated and I run over budgets, which isn't true. None of that's true and there's plenty of documentation if anybody needs it.

Many people put a green button on their collar and feel good, just like a lot of people put an American flag on their lapels and feel patriotic. It's not enough.I'm not dismissing it.

One of my unsung heroes is Erich Mendelsohn. I met him when I was a student and he was a cranky old man and very unpleasant. But if you go to his Einstein Tower in Potsdam, Germany you see an enormous intellect at work with a language that was personal and new. It has a sense of urban design and of theater and procession I hadn't seen before.

There is stuff I would have liked to have done. But there are no sour grapes.

Generally people are more impressed with the services and the comfort issues than the design.
