The work needs to have a certain longevity. It lasts longer than we do.

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.

I was in Taiwan recently and was completely amazed by the density of population. It makes New York look like no one is out on the streets.

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

Each museum is different - the collection is different, the context is different, the relationship between the art and architecture is different.

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.

You can't escape the influence of architectural history.
