Want to know what could make swimming more thrilling? Doing it 115 feet high above the ground with the view of the city right beneath you.

Residents of the Embassy Gardens Legacy buildings in Nine Elms, London will have the privilege to do just that, as the buildings’ new acrylic Sky Pool is set to open on May 19.

The new landmark is 82-feet long and stretches between the 10th stories of the two residential towers. According to the buildings’ owner, real-estate company EcoWorld Ballymore, the Sky Pool is the first freestanding acrylic pool structure in the world.

It was constructed by HAL Architects, structural engineer Eckersley O’Callaghan, and acrylic fabricator Reynolds Polymer Technology at the Reynolds factory in Colorado, USA before it was shipped to London. It was then lifted into place by a 750-tonne nzmobile crane, supported by a 50-tonne crane. The lifting was a precision process, as there was a tolerance of just 30 centimeters in installing the pool into its steel frame, said Ballymore.

“With sides 200 millimeters thick and 3.2 meters deep, and with a bottom 300 millimeters thick, the 50-tonne acrylic pool will span the 14 meters between the buildings, with steps and filtrations systems sitting either end, and five modes of lighting to add to the feeling of magic,” Embassy Gardens wrote on its website.

The pool is 10 feet deep and the water alone reportedly weighs around 375 tonnes. Bathers will be able to take in views of the London skyline, including the London Eye and Westminster.

“There are other examples of swimming pools like aqueducts connecting two buildings, like Marina Bay Sands in Singapore,” said Brian Eckersley, a structural engineer at Eckersley O’Callaghan. “But there’s never been something transparent spanning two buildings like this. Once you swim off, you can look right down. It will be like flying.”

Embassy Gardens’ Sky Pool will officially open only to residents of the buildings.
