Waterworld - Atkins Architecture Group

In an old quarry in China, Atkins Architecture Group designed this resort, taking the "natural" situation of the quarry into account. the lowest levels of the resort are based on water-oriented activities, with swimming pools, spas and such. To add an extra uniqueness to it all: there's also a bunch of underwater rooms.
Cantilevered over the edge of the quarry is an extreme sports unit, with rock-climbing features, bungee-jump installation and such.

It's not just a slick (almost kitschy) image to sell the resort, that's a bit over the top - it was a competition entry after all - but there's also a more ecological approach: the building fits in with the surrounding, but also works with ground heat extraction, green roofs and the lot.
