Burj Dubai has now become the World’s tallest building, Emaar properties said that the tower now stands at the record height of 2,257 feet or 688 meters. The skyscraper has now 160 stories and its exterior is almost done. Last summer, the developer had announced that the building surpassed Taiwan's Taipei 101 which had dominated the global skyline at 1,667 feet or 508 meters since 2004. It is worth mentioning that in the four years of construction, Emaar twice postponed the skyscraper's finish, now slated for September 2009.
