Infinity London

Plans are underway for what would be the world's first rooftop 360-degree infinity pool to be built in London.

Designs for the 600,000-litre pool and 55-story building have been unveiled by Compass Pools. The designers claim the concept is a world-first, describing the structure as "the only building in the world to incorporate a 360-degree infinity pool."

The pool (200 meters up) will be made from cast acrylic and feature transparent sides and floors. To keep views pristine, there are no stairs on the outside of the pool or the building - instead, a spiral staircase that rotates and rises through the water provides access for swimmers.

The designers envisage that the pool will sparkle like "jewel-topped torch" at night, with the building fitted with a collection of lights. There are also plans for a five-star hotel to sit underneath the pool in the top stories of the skyscraper. Construction could begin in 2020 if partners and contractors are confirmed.
