Construction just began on a sustainable hotel resort built into a 100-meter high quarry in the Songjiang district just outside Shanghai. Looking like a villain’s lair from a James Bond movie, the 19-story hotel complex will feature a huge waterfall pouring down from its roof and two of its first floors will be submerged in the water.

The five-star hotel is designed by UK architecture office Atkins for Shimao Group and will offer around 400 rooms, with underwater restaurants, clubs, shopping facilities, a 10-meter deep aquarium and various sport activities such as rock climbing and bungee jumping.
