Designs are increasingly winning competitions because they are literally green, and because somewhere they feature a small windmill.

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.

The word 'celebrity' and the word 'architect' are basically incompatible.

A building has at least two lives - the one imagined by its maker and the life it lives afterward - and they are never the same.

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.

Architecture is a dangerous mix of power and importance.
