“London, in particular, is in the throes of a heritage war. This is partly because the city is at the sharp end of the development wedge. There simply isn’t enough space for all the luxury apartments, skyscrapers with huge trading floors and “public” lookout points that you have to pay to access. Small buildings that no one really notices, but are hugely important to London’s character, are often first in the line of fire. So are the big ones.”
