The Olympic Games are highly commercialised. They purport to follow the traditions of an ancient athletics competition, but today it is the commercial aspect that is most apparent. I have seen how, through sport, cities and corporations compete against each other for financial gain.
I see the Beijing National Stadium as an architectural project. I accepted Herzog and De Meuron's invitation to collaborate on the design, and our proposal won the competition. From beginning to end, I stayed with the project. I am committed to fostering relationships between a city and its architecture.
Cities really are mental conditions. Beijing is a nightmare. A constant nightmare.
A city is a place that can offer maximum freedom. Otherwise it’s incomplete.
My image of what a city should be - the super-rich and all the poor and desperate and the people who have some kind of a desire. It's a surviving game, people trying to survive on many different levels.
New York is a city where you're so alone, you're an individual, you can disappear. You can make something happen. But it's very different to make something happen in the art world.
