Gravity-defying Pool Hangs Above Street, Aerospace experts weighed in on the design of a luxurious swimming spot dangling over Shanghai. Gravity-defying swimming pool hangs over 24-story ledge with transparent glass floor, A hotel in China offers guests a spectacular and unique view, as they swim in a pool with a glass floor while dangling 24 stories above the busy Shanghai streets.
The Holiday Inn Shanghai Pudong Kangqiao’s swimming pool is what’s known as a cantilever pool, in which part of the pool extends beyond the ledges of the building. The cantilever engineering allows the pool to extend over the edge of the hotel’s wall while being anchored only at one end. The engineering concept has been used on numerous objects, from bridges to farmhouses. Even the airplane on the bottom right of the image above uses cantilever engineering. But you don’t see very many examples of this structural design being applied to swimming pools. Particularly not ones with a glass bottom way above a busy metropolitan street.
“We wanted to provide our guests a unique swimming experience, and let them feel they’re vacationing even in a bustling city,” a spokesperson for InterContinental Hotels Group, parent company of Holiday Inn, told CNN.
Holiday Inn says it sought input from a number of professional designers and even aerospace experts before beginning construction.
