Lagos was a city that had been turned against itself. There was a bridge that became the perfect trap for crimes, which began with nails being scattered to cause flat tyres. If the driver stopped, the car would be dismantled in 20 minutes and the parts thrown overboard [to people waiting below]. The system had turned into a kind of destructive device that could be used against people. That was the narrative.

We say we want to create beauty, identity, quality, singularity. And yet, maybe in truth these cities that we have are desired. Maybe their very characterlessness provides the best context for living.

What is now called "green architecture" is an opportunistic caricature of a much deeper consideration of the issues related to sustainability that architecture has been engaged with for many years. It was one of the first professions that was deeply concerned with these issues and that had an intellectual response to them.

Escape from the architecture ghetto is one of the major drivers and has been from the very beginning.

The thing is that I have a really intense, almost compulsive need to record. But it doesn't end there, because what I record is somehow transformed into a creative thing. There is a continuity. Recording is the beginning of a conceptual production. I am somehow collapsing the two - recording and producing - into a single event.

Find optimism in the inevitable.
