An endless number of green buildings doesn't make a sustainable city.

I find it striking that the quality of the urban habitat of homo sapieans is so weakly researched compared to the habitats of gorillas, elephants, and Bengal tigers and panda bears in China…you hardly see anything on the habitat of man in the urban environment.

Only architecture that considers human scale and interaction is successful architecture.

If you make more roads, you will have more traffic.

Cultures and climates differ all over the world, but people are the same. They’ll gather in public if you give them a good place to do it.

A good city is like a good party. People don't want to leave early.

Cities must urge urban planners and architects to reinforce pedestrianism as an integrated city policy to develop lively, safe, sustainable and healthy cities. It is equally urgent to strengthen the social function of city space as a meeting place that contributes toward the aims of social sustainability and an open and democratic society.
