A far from urbane reaction to a new South Bank proposal has come from the 20th Century Society. It is furious over plans to replace the old glc 'island' block with a curious stubby tower bridge linked to a taller tower next to Nicholas Grimshaw's Waterloo Euroterminal structure. Designed by Gensler, the scheme lacks the massive elegance of its recent scheme for the new GCHQ in Cheltenham. I see trouble brewing over this one. Meanwhile, just what constitutes the 'South Bank' these days? According to the FT property correspondent Norma Cohen, in a story about Broadway Malyan's highly optimistic 380m tower block design, it includes London Bridge. Oh dear. The story also quotes Southwark's development director as saying the new London mayor will decide the future of the scheme. Actually the mayor can only block approvals, not grant them. The council may actually have to take a view.
