The US embassy brouhaha can be looked at in two ways: as a spat between two countries and their differing architectural cultures, or as part of a time-honoured process whereby London’s north bank shifts its problems and its detritus over the river onto the poor, long-suffering south bank. The cultural issues are not perhaps so absorbing. Following a thirty-year period from 1945 when American architecture led the world, its reputation has since declined. Almost all American buildings are better built than ours, but too many have become bland, safe and stodgy. The dull, all-American competition shortlist made it near certain that London would get something lacking in freshness or charm.
