I think part of the reason that London's so low rise is because of various protected views, usually of St Paul's Cathedral.

Also it's built on loam mostly on the earlier remains of Ankh Morpork on relatively soft ground.

IIRC most of London's tube lines were dug through. Where as in New York, where the bedrock is much closer to the surface, they had to dig down, then cover them over.

Another IIRC is that the BT tower has some sort of plumb line in the basement measuing if the building is tilting over time, since the foundations aren't anywhere near deep enough to hit bedrock.

Cool. I hadn't known about protected views, even though I went to school at Parliament Hill and looked at the views every day :-)
