Dubai has enhanced its reputation as a site of progression by being named the home to the tallest residential skyscraper cluster in the world. The emirate's skyline has undergone major transformation over the last decade and is now one of the most recognisable on the planet, according to the Council on Tall Buildings and Urban Habitat. Abu Dhabi, meanwhile, is a brand new entrant on the list of cities to complete the most 200 metre-plus buildings in 2011. Both emirates are the home to lots of still-to-be-completed construction sites and so there is no sign that the rate of progression is likely to slow. "In 2011, Dubai's 23 Marina became the world's tallest residential building, at 393 metres (1,289 feet)," the report said. "Coincidentally," it added, "the building sits near both The Torch (the previous world's tallest residential for a short time) and the under construction Princess Tower (set to become the world's tallest in 2012), making the Dubai Marina the tallest residential skyscraper cluster in the world."
