The tallest building in the world and still growing

"It is the tallest man-made structure in the world – and it is still growing. When complete next year the Burj Dubai will stretch half a mile into the sky over the United Arab Emirates, taller than three Canary Wharf towers balanced on top of each other. Already 2,200ft tall, and the result of 22million man hours of labour, the Burj is the pinnacle of skyscraper engineering."
