In Europe, architects consider themselves artists. They think they're special when they win a competition.

We prefer synthetic rather than natural materials. Natural products are almost too valuable. Wood is much harder to produce than metal. And metal is recyclable, while wood isn't.

Transparency is not the same as looking straight through a building: it's not just a physical idea, it's also an intellectual one.

A city building, you experience when you walk; a suburban building, you experience when you drive.

A building is hard to judge. It takes many years to find out whether it works. It's not as simple as asking the people in the office whether they like it.

The architecture profession has lost a lot of its integrity, especially in the USA. The general architect here has no scruples, no ambitions.
