A look at China's new doughnut-shaped hotel It's the newest concept building to mark China's skyline. Following the opening of the world's largest building where the sun shines 24/7, and the construction of a five-star 'groundscaping' hotel built into a former mine, this hotel has a unique shape all its own: a glowing doughnut. Officially known as Sheraton Huzhou Hot Spring Resort, this 27-story building is located in the city of Huzhou, near Shanghai. Designed by Beijing-born architect Ma Yansong, the hotel appears to give off the appearance of a horseshoe, though the bottom ends are connected by two underground floors. According to Sheraton's website, the resort offers 321 spacious guest rooms, including 44 suites and 39 villas, all with private balconies. The opulent lobby has 20,000 Swarovski and European natural crystal lamps on its ceiling which are arranged in a wave-like formation, and the floor is paved with Afghanistan White Jade and Tiger's Eye Stone from Brazil. The hotel also features the company's "Shine Spa for Sheraton," with facilities including a steam room, saunas, and a hydrotherapy pool in each locker room. For dining options, guests can choose from three restaurants and two lounges for an array of domestic and international food. Currently in a soft-open phase, the hotel will officially open to the public in October 2013, and rooms are expected to cost about $400 per night.
