It's very important for cities all around the world to reinvent themselves, and Glasgow is a good example of that. The Scots are very nice. I don't think they are burdened by their history.

Wherever I am in the world, my perfect day begins with waking up and heading to the beach or the pool or somewhere I can be semi-comatose. I just wake up and go to the sun.

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.

I find industrial cities exciting. I like their toughness.

When you are overworked and exhausted, there is a sense of kind of delirium and that's why I think architects do all-nighters and they kind of do those deadlines. For four days I remember doing four nights in one row with no sleep. I mean nobody, unless you are crazy, would do that, but you are totally focused on the project.

Of course there is a lot of fluidity now between art, architecture and fashion - a lot more cross-pollination in the disciplines, but this isn't about competition, it's about collaboration and what these practices and processes can contribute to one another.

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.
