What are the structural and arhictectural implications of the World Trade Center attack on the future of the world's cities?
Building high has never been a simple case of hubris. Ever-rising land prices encourage us to reach, however unpredictably, further upwards. In the case of New York, Hong Kong or Tokyo, there is only a given amount of land to build on. Just as steam rises through the safety valves of a boiler at a certain pressure, so eventually city buildings must begin their ascent above the classical skyline. But, anticipating earthquake, fire or terrorist attack, should we be thinking of dispersing commercial centres?
