It's been like a large-scale test of our design intentions. That doesn't mean that this kind of building is an experiment in Hong Kong. It's just as easy to work in Hong Kong as in Boston, although we can't do identical things. Sometimes we get things done better, sometimes worse. It's important to have an associate in the place, someone who can guide us through the craft subcultures.
Cultural differences are very small.
It's not difficult as long as one is respectful of the people one works with. It's been more complicated working in Buenos Aires than in Hong Kong. I find the design of very tall buildings to be the most interesting of architectural projects. They need to operate with as close to optimum efficiency as possible. The financial requirements are so great that they cannot cope with the inefficiencies that are tolerated in lower buildings.
