Built into the sidewall of a decommissioned quarry, the 18-storey Intercontinental Shanghai Wonderland two floors above ground and 16 below ground level, including two entire floors of underwater suites looking into a 10-metre deep aquarium.
Guests on the other levels get panoramic views of a cascading glass waterfall and exposed rock on the opposite side of the quarry.
In addition, the hotel plans to generate its own geothermal and solar energy to power everyday functions.
Located 30 kilometres from Shanghai’s Hongqiao airport in the Sheshan Mountain Range, the 336-room hotel comes complete with sports and recreation facilities including rock climbing, kayaking, and bungee jumping.
There’s also a nightly light show and, in a nod to the hotel’s location, a Quarry Bar.
Rooms are priced from 3,394 yuan (A$668) a night, according to the Intercontinental Hotels and Resorts website, while the maximum price for a suite is more than a whopping A$14,000 and comes with butler service.
Despite being dubbed by some media outlets as the world’s first underground hotel, there are actually dozens of underground accommodations around the world from Coober Pedy in South Australia to the Grand Canyon Caverns.
However, no other hotels appear to be built in a former quarry or resemble a five-star luxury hotel.
The swanky five-star resort, also known as Shimao Quarry Hotel, has reportedly taken 12 years and some 5,000 architects, engineers, designers and construction workers to build.
The project initially broke ground in 2012, but construction did not start until late 2013 and the project has been beset by several delays, notes The Urban Developer.
One such project involved pumping concrete downward by 80 metres without blockages, or separation of sand and cement.
Engineers counteracted this issue by changing the ratio of constituent materials and adding a damping device to slow its descent.
British architect Martin Jochman, who designed the hotel, was also the brains behind the luxury hotel Al Arab Jumeirah in Dubai, which has a structure that resembles the sail of a ship.
Mr Jochman told Xinhua the quarry pit was the source for his inspiration, and that he wanted to build a hotel that integrated with its natural environment.
“This is such a unique opportunity that gives me some really interesting ideas of reshaping the relationship between city and nature.”
The unique design has been honoured by multiple prestigious awards, including “Best Chinese Futura Projects Awards by MIPIM Asia 2011 as well as “Best Hotel Architecture China”, “Best Hotel Architecture Asia Pacific” and “Best International Hotel Architecture” by International Hotel Awards 2013.
