Found on Cool Hunting, the Waterworld Hotel was designed by Atkin’s Architecture Group. This spectacular water filled quarry in Songjiang, China, is a 400 bed resort hotel constructed within the natural elements of the quarry. Underwater public areas and guest rooms add to the uniqueness, but the resort also boasts cafes, restaurants and sporting facilities. The hill was transformed in roof-gardens with terraces with a waterfall at the center. The waterfall is a transparent glass volume which is a central vertical circulation atrium connecting the quarry base with the ground level.

For the fans of extreme sports there is the rocky gym and a bungee jumping. And of course you can find a waterfall with a swimming pool, besides the possibility to practice various sportive activities linked to the water world.
