The design includes three linked elements: a wave-shaped 333,333-sq.-ft. (30,000-sq.-m) above-ground "land station" and the jellyfish-shaped 833,333-sq.-ft. (75,000-sq.-m.) underwater hotel, linked by a submerged transparent train tunnel that's 1,700 feet (515 meters) long.

Among the project's other unusual architectural details are the hotel's two translucent domes, which will house a concert auditorium and a ballroom that break the water's surface, with the ballroom featuring a retractable roof. And that's not to mention the hotels
