Ultimately it's the public nature of those projects that I most enjoy. Museums are more than just places to view art, they're also civic and social centers.

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.

We look at each one [project] and consider the context - what it is and what it can be - beyond the strictly functional concerns.

It's important to understand differences in scale and environment.

We are all affected by Le Corbusier, Frank Lloyd Wright, Alvar Aalto, and Mies van der Rohe. But no less than Bramante, Borromini, and Bernini. Architecture is a tradition, a long continuum. Whether we break with tradition or enhance it, we are still connected to that past. We evolve.

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

You can't escape the influence of architectural history.
