The outcome is architecture as diverse as Zaha Hadid, whose Contemporary Art Center opened in Cincinnati in 2003, David Adjaye, who has designed a series of radical libraries for East London, and the ironically-named Foreign Office Architects (FOA), who leapt to prominence with their competition-winning design for the Yokohama Port Terminal in Japan, opened in 2002. FOA represented Britain at the Architecture Biennale in Venice that same year.

One of the greatest challenges being tackled by British architecture now is truly sustainable design. Our single most successful architect, Lord Foster, believes that it is now technically possible to build the world's first energy-neutral skyscraper. In other words, a huge building, a complete community, that can naturally generate as much power as it consumes. When will it be built? What will it look like? We are working on it. By Hugh Pearman
