There are few things more fun than the “look at me!” phenomenon of trying to build the world’s tallest building. You’ve got your gigantic skyscrapers that beat out the ones by just a couple of feet and thus take the title and your “the towers on top don’t count!” kinds of people. Really, it’s one of those things that have been going on since the beginning of time, when Grogg built his rock pile slightly taller than Froog’s (those are authentic cavemen names, by the way). The Sun Times is reporting that we’re in the thick of it again, as locally, Adrian Smith, famous former partner at Skidmore, Owings & Merrill, the architecture firm that designed the US’ tallest, the Sears Tower, has said that the still-in-construction Burj Dubai in the United Arab Emirates has just this weekend become the world’s tallest building, surpassing the former, Taiwan’s Tapei 101 by just 9 feet. What’s more, it’s still rising and no one knows how tall it’ll wind up being in the end, as it’s a closely-guarded secret. But rest assured that once it’s done, it will hold its title for upwards of twenty-three minutes before something bigger comes along.
