Sky Pool

It’s a bird! It’s a plane! It’s … a person swimming laps? This may well occur in London, where design firm Arup Associates released plans for a 90-ft.-long (27 m) pool suspended 10 stories up between two residential buildings in the city’s Nine Elms neighborhood. (Construction is set to wrap in 2019.) Once completed, however, the so-called sky pool won’t be open to everyone–just residents of the Embassy Gardens luxury apartment complex. The price of admission: at least $940,000 per unit.
