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.

For me [ Giovanni Lorenzo ] Bernini, [Francesco ] Borromini, and [Donato] Bramante have been as significant as Alvar Aalto, Frank Lloyd Wright, Le Corbusier, and Louis Kahn. I still marvel at their works, which have a quality and a timelessness that I seek to have in our projects.

Winning the competition for Frankfurt's Museum of Applied Art in '79 opened the door to a number of projects in Europe, especially as we were invited to join many design competitions.

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.

When I think of a place of worship, I think of a place where one can sit and be reminded of all the things that are important outside our individual lives. To express spirituality, the architect has to think of the original material of architecture, space and light.
