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.

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.

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.

Rome has not seen a modern building in more than half a century. It is a city frozen in time.

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.

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.

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