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.

Quotes from the same author

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.

We know that Las Vegas is junk, but at the same time I think that exactly the same process and ultimately also, perhaps the same logic, attaches itself to or underlies our masterpieces. We live in an amazing era when in spite of an absence of masters there is an explosion of masterpieces.

The real thing we tried to look at is what happens to a society when the state is absent. At that point, the state had really withdrawn from Lagos; the city was left to its own devices, both in terms of money and services. That, by definition, created an unbelievable proliferation of independent agency: each citizen needed to take, in any day, maybe 400 or 500 independent decisions on how to survive that extremely complex system.

I'd say that my profession ends where architectural thinking ends - architectural thinking in terms of thinking about programs and organizational structure. These abstractions play a role in many other disciplines, and those disciplines are now defining their 'architectures' as well.

Any architectural project we do takes at least four or five years, so increasingly there is a discrepancy between the acceleration of culture and the continuing slowness of architecture.
