Infinity pools are a staple of beachside resorts and high-end hotels – but you probably haven’t seen one quite like this. Compass Pools is planning to build an infinity pool at the top of a 55-story London skyscraper, providing a 360-degree view of the skyline.

But there’s just one problem: People are confused about how you’re supposed to enter and exit the pool.

Compass Pools’ website says that swimmers would use a spiral staircase “based on the door of a submarine” that rises from the pool’s floor. Alex Kemsley, a pool designer and technical director for Compass Pools, told INSIDER that the staircase would work like “a tube in a tube.”

“The first tube is to ‘cut a path’ through the water and create an airlock,” Kemsley said. “The second to deliver the staircase up to water level.” The company opted not to add stairs to the outside of the building or the pool because it would spoil the view.

Kemsley added that the staircase would be controlled by a programmable logic controller to ensure that all locks and valves operate at the correct time.

But that didn't stop onlookers from speculating how swimmers would get in and out of the pool.

Many people compared the pool's design to a real-life experiment in the popular life-simulator video game "The Sims" gone awry.

Construction on the tower could start in 2020, Compass Pools said, and the top floors are designed to include a five-star hotel, a spa, apartments, and luxury retail outposts.

Other than its mysterious entry-and-exit mechanism, the pool would feature a clear floor so that swimmers can see the guests below and vice versa, as well as an anemometer to measure the wind speed, ensuring water doesn't spill out to the street below.
