The Ramside Hall Hotel in Durham, UK, has unveiled artists impressions of spa facilities that will be added to the estate as part of an £18m (US$29m, €23m) investment plan.

£3m (US$5m, €4m) of the total has already been used to create an 18-hole golf course, which was launched earlier this year. The remaining £15m (US$24m, €19m) will be spent on the construction of 47 additional luxury guestrooms – taking the total number of hotel rooms to 128 – plus the development of a spa.

Set to officially open in May 2015, the spa will feature a range of facilities, including a 25m swimming pool, hydrotherapy pool, saunas and a range of steamrooms. Plans for the project include an outdoor balcony with an infinity pool, a caldarium and a rasul mud chamber.

The spa will offer 12 treatment rooms. Other leisure facilities to be developed include a gym, dance studio, hair salon and an Asian-style restaurant and bar.

“This is a huge development for the hotel and will be a massive boost for the North East,” Tim Boyd, general manager at Ramside Hall Hotel, told local newspaper The Northern Echo. “We’re creating an amazing state-of-the-art leisure facility which will be suited to everyone, from visitors who want to get fit and keep in shape, to anyone who just wants some rest and relaxation.

“At the same time, the addition of the extra rooms give the hotel even more capacity to cope with leisure and business travellers,” said Boyd.
