An architect is given a program, budget, place, and schedule. Sometimes the end product rises to art - or at least people call it that.

Picasso could use everyone's paintings and transform them into his own. He was using ideas from all of his contemporaries.

There is a backlash against me and everyone who has done buildings that have movement and feeling.

In Tokyo, London or Los Angeles people go into McDonald's and the restaurants are identical and people are comfortable. It's unthreatening.

China is building cities for a 20 to 40 percent increase in population. India is quickly growing. The carbon footprints of that and other development around the world are overwhelming.

On certain projects, on big public projects, people definitely are interested in making them greener, but on smaller projects with tight budgets it can be harder.

If you know where it's going, it's not worth doing.
