Miami Worldcenter’s 60-story Paramount condo tower is being built to accommodate flying cars, the developer has announced.

Dan Kodsi told the WSJ that he expects air taxis will be available within 10 to 15 years, and is preparing for them by building a skyport.

At Paramount, the rooftop will have a “hidden” swimming pool fitted with a hydraulic floor. Within minutes, the pool can transform into a 3,000 square foot landing surface. An indoor area that will at first be used as an observatory will eventually become a sky lobby for the air taxis.

Uber has said that they plan to launch a VTOL (vertical takeoff and landing) air taxi service by 2023. About a dozen companies are now working to develop the flying vehicles, which will use propellers to go airborne and travel at speeds up to 230 miles per hour.
