Let's do it right. This is for the ages.

Success is a collection of problems solved.

François Mitterrand was a student of architecture, he had done a lot of research before he called me. He said, "You did something special at the National Gallery of Art in Washington - you brought the new and the old together." But John Russell Pope finished the West Building in 1941, so when the East Building opened it was only about 40 years old. But the Louvre is 800 years old! A much bigger design challenge.

Contemporary architects tend to impose modernity on something. There is a certain concern for history but it’s not very deep. I understand that time has changed, we have evolved. But I don’t want to forget the beginning. A lasting architecture has to have roots.

My projects have typically taken a long time to complete. Buildings might take on average about five to seven years to finish, but in my case it's been longer, because the projects I have accepted within the past 15 years have been mostly government projects, and those involve some politics and funding issues, and approvals and so forth. So they're slower.

It is not an individual act, architecture. You have to consider your client. Only out of that can you produce great architecture. You cannot work in the abstract

I travel to the Middle East, I travel to China, I travel to Europe. It's all very rewarding - the only problem is the travel is getting more and more difficult for me now. Ten years ago I would have enjoyed it a lot more.
