A twenty five metre long, ten storey high suspended swimming pool—dubbed the 'Sky Pool'—has been planned for the second phase of a new high-end residential development in the London district of Nine Elms, next to the new Embassy of the United States. The pool is part of two buildings, designed by London-based practice HAL and part of a complex of 2000 homes developed Ireland's Ballymore Group. The water will be held in suspension by just twenty centimetres of "structure free" transparent glass, and will connect two housing blocks together. Alongside a rooftop bar, orangery and spa, a second connection between the two is also planned in the form of a footbridge.
