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.

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.

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

To be an architect has been a life-long dream. Little did I know when asked at the age of 14 'what do you want to do when you grow up?' I said I wanted to be an architect. After 50 years I am still learning all what that means. Working together with so many people has been enormously gratifying. Being an architect means being a member of a fantastic team.

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.

You can't escape the influence of architectural history.

Whiteness allows the architectural ideas to be understood most clearly - the difference between opacity and transparency, solid and void, structure and surface. These things are more perceptible in a white environment. They have a greater clarity.
