Is there is a panorama of London these days that can best what meets the eye on Lambeth Bridge? The classic prospect of the Houses of Parliament commands attention, of course, but so does, in quite a different way, the upstream vista. There, Millbank Tower surges skyward, proclaiming the arrival of modernism since 1963, while apparently seeding the newer, smaller and more exotic versions of itself that have been springing up on the opposite bank, frolicking in the shade of their parent tree all the way down to Nine Elms and the new diplomatic precinct at Embassy Gardens.
