The reason for the boom is that building skyscrapers got a lot cheaper in the last 10 years as the techniques and approaches have been worked out in the Middle East and China. It's not really anything to do with the economy - just the chance to create a lot of office space cheap. I think that the other factor is the Queen Elizabeth line which will bring a lot of commuters from the west of london and outlying areas into city of london range. I expect docklands to be the big loser.
