I miss aspects of being in the Arab world - the language - and there is a tranquility in these cities with great rivers. Whether it's Cairo or Baghdad, you sit there and you think, 'This river has flown here for thousands of years.' There are magical moments in these places.

From my first days studying architecture at the architectural association, I have always been interested in the concept of fragmentation and with ideas of abstraction and explosion, where we were de-constructing ideas of repetitiveness and mass production.

I've always been interested in combining architecture with a social agenda, and I really think you can invest and be inventive with hospitals and housing.

You really have to have a goal. The goal posts might shift, but you should have a goal. Know what it is you want to find out.

Contrary to popular view, I've never been patronized in the Middle East. Men maybe treat women differently, but they do not treat them with disrespect. They don't hate women. It's a very different kind of mentality.

I'm trying to discover - invent, I suppose - an architecture, and forms of urban planning, that do something of the same thing in a contemporary way. I started out trying to create buildings that would sparkle like isolated jewels; now I want them to connect, to form a new kind of landscape, to flow together with contemporary cities and the lives of their peoples.

One has to strive for a very open liberal society.
