London is about to get what’s described as the world’s very first sky pool, a 90-foot long glass-bottom sky pool that floats in the air, offering the feel as if you’re swimming in the sky.

The stunning glass-encased outdoor swimming pool, will be suspended 10 stories up, providing a “bridge” between two apartment blocks with communal rooftop sun terraces.

Entirely transparent, it measures 90 feet long by 19 feet wide and is nearly 10 feet deep, with a water depth of about four feet.

Onsite construction begins this year, and in 2018 buyers can begin moving in.

Sean Mulryan, chairman and CEO of Ballymore Group, who is working on the design with Eco World, said, “My vision for the Sky Pool stemmed from a desire to push the boundaries in the capability of construction and engineering. I wanted to do something that had never been done before. The Sky Pool’s transparent structure is the result of significant advancements in technologies over the last decade. The experience of the pool will be truly unique; it will feel like floating through the air in central London.”

A “Sky Deck” at the top of the two buildings will also feature a spa, summer bar and Orangery for residents to relax.

Swimming in the sky – an amazing, or terrifying experience, depending on your perspective.
