It was a book [George Packer written on our presence in Nigeria] that was killed by the response of other people. Which sounds quite cowardly, perhaps, but it was the first manifestation of what is currently a really big issue: how political correctness defines the limits of what you can do. In that sense, it was super-exciting and maybe the most magical project we did, but at the same time fraught with mixed feelings.

Asia is still dominated by skyscrapers. I hope that, in European cities, it will become a declining trend. They were almost never necessary.

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.

Japan lives with drastic segregation between the sublime, the ugly, and the utterly without qualities. Dominance of the last 2 categories makes mere presence of the first stunning: when beauty 'happens', it is absolutely surprising.

At that time [90th in Lagos], if you drove through the city, you drove through a foreground that always seemed to be incredibly dramatic and incredibly agonised - smoking, burning, incredible compression. In the first year we stayed on the ground and went everywhere. But then in order to discover whether this was the whole story, we rented a helicopter. And we began to understand that this is not chaos but a highly modern system that had been abandoned, then at some point went into reversal, then slowly came out of it.

I like fashion, whether or not it's overpriced, because it creates a sense of the sublime with relatively few means.
