Only through acknowledgment of the erasure and void of Jewish life can the history of Berlin and Europe have a human future.

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

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

Architecture is not based on concrete and steel, and the elements of the soil. It's based on wonder.

It's about how to bring together the seemingly contradictory aspects of the memorial, which is about a tragedy and how it changed the world, but also about creating a vital and beautiful city of the 21st century.

We often judge cities by great public buildings. But we admire great cities because people live there in a beautiful way. You have to think about how each person will live there; you can't just think about abstract ideas.

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.
