The people from the suburbs are bringing along their suburban values: cleanliness, orderliness, safety - dullness, in other words. As a result, urban areas are being hollowed out. Just look at Times Square in New York. No more sex shops, no drugs, no homeless people. The area is clinically clean and incredibly dull.

There is no plateau of resting or stabilising. Once you are interested in how things evolve, you have a kind of never-ending perspective, because it means you are interested in articulating the evolution, and therefore the potential change, the potential redefinition.

We say we want to create beauty, identity, quality, singularity. And yet, maybe in truth these cities that we have are desired. Maybe their very characterlessness provides the best context for living.

Miami Beach is a completely interesting hybrid because it is, on the one hand, a resort and, on the other hand, a real city. This condition of city and water on two sides I think is really amazing. And in the heart of that city, it has put an enormous convention center, an enormous physical presence.

Beauty isn't what I'm primarily interested in [in architecture]. I think appropriateness is more important.

There are essentially two possibilities. One is to be, shall we say, an average architect and do the same thing everywhere. The other is to let yourself be inspired and even changed by the unique qualities of the place where you're building. We always try to take the second approach.

Lagos has also had a particular effect on my career. I was there early, and although it was a courageous step to go there and invest on this scale - I went there maybe 20 times - it's also been also super-controversial. There's an old school of thought that somebody like me has no place to go there.Because of colonialism and so on.
