Kempinski will unveil its largest ever property in China this May – a 14sq km (5.4sq m) hotel, villa and spa complex which is being lined up as a possible host for major political events such as APEC 2014 and future G20 summits.

Set at the foot of the Yanshan Mountains, 60km (37.3m) north of Beijing city centre and 25km (15.5m) from the Great Wall of China’s Mutianyu section, the development comprises 595 guest rooms and suites. Of these, 306-bedrooms are in Yanqi Lake Kempinski Hotel Beijing, located on the mainland, while there are 111 rooms at the State Guest House and 178 rooms spread across 12 boutique villas on a private island.

The Kempinski The Spa is spread over the whole complex, with the main area in the Kempinski Hotel boasting four floors of health and wellness including eight treatment rooms, plus a pool, gym, juice bar and tea area.

The spa in the State Guest House features 11 luxury treatment suites, including a VIP room with its own hammam and two treatment beds, in addition to a thermal area, relaxation area, foot massage rooms plus a gym, exercise studio and games rooms.

Each of the boutique villas – which range between 5,000 to 9,000sq metres (53,820 to 96,875sq ft) and are envisaged as being individual lodgings for heads of state attending summits – has its own spa, 25m lap pool and gymnasium. The villa spas feature individual designs by well-known international agencies such as, Wilson, Rockwell, HBA and DiLeonardo.

Product brands are yet to be finalised across the spa sites, with an earlier tie-up falling through due to registration issues.

Ecology is to be a big focus of the hotel, which utilises a range of materials and energy supplies, as well as supporting local efforts to improve the air quality by cracking down on industrial polluters and controlling vehicle emissions.

“The spa will combine beauty and nature through our world-renowned designers, where sustainability and ecological values remain their core consideration when choosing materials and construction techniques,” said general manager Brice Péan.

“Electricity is supplied from green hydroelectric power, lighting consists of LED systems and eco-friendly products are used throughout the resort.”

Away from the spa offerings, other leisure facilities include a marina, 18-hole golf course, recreational, fitness facilities and a Kid’s Club.

The resort’s culinary team aims to provide Yanqi Lake’s local community and travellers a combination of luxurious European hospitality and Chinese tradition.

There are 14 food and beverage establishments in the development, including the German restaurant and bar Paulaner Brauhaus, where guests can enjoy imported cheeses, cold cuts, sausages, freshly-baked breads, wine and cigars.

With its political aspirations in mind, the resort also gives over a vast amount of space to business facilities. There is 14,069sq metres (151,437sq ft) of meeting space, including an 8,277sq metres (89,093sq ft) conference centre and outdoor event spaces in landscaped gardens.
