Architecture is not just for the moment, it is not just for the next fashion magazine.

You cannot suddenly make Lower Manhattan into a sad place because we saw such a dramatic loss of life. You have to balance the memory, which is so important, and use it as a kind of Archimedean Point to create a lively, incredibly interesting, and culturally significant piece of a city and neighborhood.

And of course I like Berlin a lot. It's such an interesting city

Buffer between commercial, memorial and retail space.

Winning a competition in architecture is a ticket to oblivion. It's just an idea. Ninety-nine per cent never get built.

Call Berlin. Drop everything we're doing. I have a complete vision of what should be.

I think there is a new awareness in this 21st century that design is as important to where and how we live as it is for museums, concert halls and civic buildings.
