Dubai is planning to build one of its most elaborate structures yet with developers promising that it will dwarf the current world's tallest building – the Burj Khalifa. The new tower, based at the centre of a new development called Dubai Creek Harbour, is set to boast rotating balconies and landscaping inspired by the mythical hanging gardens of Babylon. Costing about $1bn the tower would be a "gift to the city before 2020" – when Dubai hosts the Expo trade fair for real estate and development. http://www.ibtimes.co.uk/dubai-build-1bn-babylon-inspired-tower-taller-burj-khalifa-1554108
