If you thought your annual dip in the icy local lido was brave, feast your goggles on this.
The crazy folk at Compass Pools have developed ‘Infinity London’, a 600,000-litre pool which will sit on top of a 55-storey building.
If planning permission is granted, you could be casually paddling 200 metres above the city by 2020, with 360-degree views of the city. For some, we're sure it will sound like the best breast stoke of their lives, and for others extreme torture.
‘Do I need a helicopter to access it?’ we hear you cry. Pff, of course not. Compass Pools claim that ‘swimmers will access the pool through a rotating spiral staircase based on the door of a submarine, rising from the pool floor when someone wants to get in or out’. Additional fancy features include a heating system powered by waste energy (ooh!) and a built-in anemometer (fancy!) to gauge wind speed.
If this all sounds too high up and high-tech to handle, the pool will still be a spectacle for less daring onlookers. Pretty lights will make it glow like a torch at dusk and the floor of the pool will be completely transparent, allowing visitors to see the swimmers above.
See, it’s safe, so long as everyone wears appropriate swimwear.
