It promises to be the best new tower in London for well over 30 years, and the first of a possible new wave by the likes of Grimshaw and Richard Rogers and Renzo Piano. The computer power that ran amuck on City Hall has here been harnessed in the cause of beauty and sophistication. Or so it seems, thus far. Let's hope they don't goof on the details. Meanwhile Foster is using the same radical triangulated exo-skeleton technology to build an utterly different 42-storey tower for the Hearst Corporation in Manhattan. It will be a crinkle-crankle affair, interesting rather than lovely. But again, true to its time, its location, and its function.
