On our blink-and-you'll-miss-it visit to the world's largest building site, aka Dubai, we stopped for a gawk at this, the Burj Dubai. Currently the tallest structure in the world, it stands at 156 stories and 585 meters high, but is expected to reach around 800 meters when finished. Designed by Adrian Smith, the tower continues the Armani-Samsung love-in, as the Italian designer is putting his name to a sexy hotel, while the Korean mega-corp is one of the three constructors on the skyscraper. But the cruelest cut of all is that Burj Dubai (burj means "tower" in Arabic) will be dwarfed by Kuwait's Burj Mubarak Al-Kabir, which will measure 1,001 meters when it is ready. But that's not expected to be until 2012 so, until then, size queens will be eyeing up Dubai. [Burj Dubai]
