I need to plug this site: Skyscraper Page.
Despite its not so imaginative name*, the site is a veritable gold mine of information both awesome and mundane, listing skyscrapers all over the world, with their construction dates, heights, floor count, and other information, along with scale sketches for most. Sadly, though it lists every building in Christchurch over 10 floors, the only one with a sketch is the Hotel Grand Chancellor, but I guess that’s reasonable, seeing as they’re all being shaken to pieces.
Really, though, it’s all about comparing ridiculous mega-engineering projects – check out this diagram of the likely world’s tallest buildings in 2015..
That’s a seriously huge clock-tower (click to zoom).
* I can’t help but think that web pages named with the word page at the end just sound silly, like “Lord of the Rings Book” or “Moby Dick Book”. I guess “The Jungle Book” is a good counter example, but doesn’t “The Page of Skyscrapers!” have more of an impressive ring to it?
