The the five-star InterContinental Songjiang Shimao hotel, which is being built inside an abandoned quarry in China located at the base of Tianmenshan Mountain.
The hotel is designed by UK architecture firm Atkins, who won the competition bid in 2006.
Construction has started on the resort that will be nestled into a 100 meter-high rock face of an abandoned water-filled quarry outside Shanghai and will take up to three years to complete, at a cost of $548 million to build. The hotel could open as early as 2015.
A huge waterfall will pour down from the roof of the 19-stores hotel complex, which will have part of its body built into the cave and two of its floors submerged beneath the water.
The building will use geothermal technologies to generate its own electricity and lighting, while greenery will blanket a roof that extends just two storeys above the edge of the quarry.
The hotel will offer around 400 rooms, as well as conference facilities for up to 1000 people, a banqueting hall, restaurants, a swimming pool and a water-sports centre.
