Sustainability has become an ornament.

I studied in London in 1968. Our school had a separate department of tropical architecture. Of course it was totally unfashionable, partly because nobody wanted to think about colonialism, but basically what you learned there was that, OK, the sun is here, so you should create natural ventilation here - an unbelievable amount of really sound principles that have been completely abandoned, so now everything is air conditioned with big machines.

But now sustainability is such a political category that it's getting more and more difficult to think about it in a serious way. Sustainability has become an ornament.

Our office acts like a kind of educational establishment and we are very careful who we educate.

Talk about beauty and you get boring answers, but talk about ugliness and things get interesting.

When shopping was still connected to the street it was also an intensification and articulation of the street. Now it has become utterly independent - contained, controlled, surveyed.

It is not possible to live in this age if you don't have a sense of many contradictory forces.
