The world has changed a great deal from when I began 50 years ago. I was very fortunate. There were a lot of opportunities that perhaps don't exist today.

If I had my druthers, I would do a lot more.

One of the real challenges, since we're working in so many places - Mexico, Japan, Brazil - is understanding variations, both in terms of culture and context.

Architecture which enters into a symbiosis with light does not merely create form in light, by day and at night, but allow light to become form.

We think about project's public nature and how that can be enhanced, how the spaces we create can enliven the experience of being there.

Any work of architecture that has with it some discussion, some polemic, I think is good. It shows that people are interested, people are involved.
