because there are rules about how tall buildings can be in london. Which is a gooo thing because skyscrapers look horrible and cast a shadow.
You can't really compare London to Hong Kong and New York City, both the latter had limited space to build upon so as the population exploded up was really the only way to go. Thats why you see so many skyscrapers on Manhattan but comparitively much less in Queens, the Bronx etc as theres much more room to spread outwards as London did. The vast majority of the UK's skyscrapers are business related not mixed use or residential unlike NYC and HK.
It wasn't really until Livingstone's time as Mayor either that you can get a skyscraper built in London (aside from the Natwest and a few others) because of English heritage and a desire to retain London's historic skyline. They're sprouting up all over the place though now, every day I walk down Mile End Road I can see the Heron getting taller and taller and just around the corner the Pinnacle finally being built. Give it another 20 years and the City will be a cluster of skyscrapers, Canary Wharf is being expanded in the next few years aswell with three more 'scrapers.
I am currently writing a 12,000 word dissertation on exactly this topic. If anyone is interested in reading it for a full explanation then just email me.
I've always thought it ludicrous that we haven't adopted skyscrapers widely. They are a fantastic space saving measure. I'm glad that they seem to be popping up more in London and elsewhere around the country, if we had it my way the only developments that could be proposed in major cities would be skyscrapers dammit!
A big reason is that in London the ground is really soft and its costs loads to build the foundations, however places like new york have the perfect ground to build on. Also years ago in London there were not really space issues where we needed to build high like in new york
Most skyscrapers are either nondescript boxes or fugly vanity projects imo.
it's a pain in the butt to live/work in them and there's no real need.
I'm not a fan.
I like how the UK doesn't have loads of sky scrapers.
It sets its cities apart from the skyscraper filled cities elsewhere (which you probably wouldn't be able to distinguish between if you were shown unnamed pictures of them).
