World's first infinity pool with 360-degree view to open in London

London is set to get the world's first infinity pool with a 360-degree view atop a 55-storey building and its construction may begin as early as 2020. Compass Pools, a UK-based pool manufacturer, has unveiled its design for a 6,00,000-litre pool 'Infinity London'. Swimmers will enter or exit through a rotating spiral staircase that rises from the pool floor.
