The work in S, M, L, XL was almost suicidal. It required so much effort that our office almost went bankrupt.

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.

As more and more architecture is finally unmasked as the mere organization of flow - shopping centers, airports - it is evident that circulation is what makes or breaks public architecture.

Why I talked about political correctness: the colonial is now such a major taboo that any achievement of the colonial period, or any generosity implied in colonialism, is again fundamentally neglected or fundamentally not recognised. That's crazy, because history is a series of layers, and you cannot say, "This layer I support and this layer I cancel." History is history and you cannot retrospectively manipulate it.

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.

In Lagos there's a really strong case to resurrect strong parts. Embedded in all of it are some amazing pieces of planning, amazing pieces of engineering and interaction. For instance, the campus of Lagos University is stunningly beautiful, efficient and generous, and that needs to be recognised and preserved.

One cannot completely avoid this landmark character with large buildings such as these. But the city itself is also gigantic.
