I will always have two regrets. I don't have a presence in London, and I would have liked to have done more work in the Middle East.

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.

Architecture is how the person places herself in the space. Fashion is about how you place the object on the person.

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.

Architecture is unnecessarily difficult. It's very tough.

For many years, I hated nature. As a student, I refused to put a plant anywhere - a living plant, that is. Dead plants were OK.

You don't always have to show art in what's called a white box; you can have a kind of complexity within an exhibit which actually respects the art as well.
