No, no, no, no, no, no…. I’m not THAT afraid of heights but this freaks me out. It will be a ‘World’s First” when it’s completed in 2017. This 90 feet long, glass bottomed swimming pool will be part of Nine Elms, a riverside district under construction in South London. Suspended 10 stories above ground, the pool will bridge two apartment buildings making it possible to swim laps between the two structures. I don’t know that it’s a real selling point but regardless, it’s beautiful.
