Deyan Sudjic was trained as an architect, but became a critic, curator, and writer. He is now director of the Design Museum London. In this interview he talks, among other things, about why people really build things.

While writing his book The Edifice Complex, he discovered that the reasons for building tall have not really changed. People build to make a mark, show who's powerful, to create a sense of national identity, and to create reflections of ego. What he doesn't mention are the business drivers for exuberant projects.

Sudjic also claims, that this is a landmark moment for architecture, design, and culture. A generation of architects is used to insane growth, development and huge projects. Their successors will have to understand how to survive in a very different climate, he envisions.
