If you want creativity, take a zero off your budget. If you want sustainability, take off two zeros.

The car is the cigarette of the future.

There is little in the architecture of a city that is more beautifully designed than a tree.

Creativity starts when you cut a zero from your budget.

The secret to the city is integration. Every area of the city should combine work, leisure and culture. Separate these functions and parts of the city die.
