Designed by a Singaporean architectural firm, Holiday Inn Shanghai Pudong Kangqiao's indoor swimming pool comes complete with its own exterior protrusion — which just so happens to be suspended 24 stories in the air.

The external element was fitted with a toughened-glass bottom that offers guests vertigo-inducing views of the street blow.

"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 Holiday Inn's parent company, InterContinental Hotels Group, told CNNGo.

A Holiday Inn Shanghai rep told the news network various architects and aerospace experts were consulted during the construction of the pool to ensure public safety.
