Stanley House estate, in the Ribble Valley, UK has completed the final chapter in a major investment programme with the launch of a day spa, 18 new bedrooms and an extension to the bar and brasserie.

Spanning two floors, the multi-million pound 932sq m (11,000sq ft) spa has a rural theme. There are five treatment rooms, relaxation rooms, a thermal suite, hydro pool with mood lighting, a double treatment suite with Rasul or private steamroom, a Finnish sauna with panoramic views, experience showers and an ice fountain, as well as a gym and pilates studio.

A top team were charged with creating the spa: Howard Spa Consulting, which counts the London Dorchester among its clients, delivered the project. Trevillion Interiors, which has formerly worked for Raymond Blanc's Le Manoir aux Quat'Saisons in Oxford, created the funky interior. Barr & Wray and Thermarium provided the hydro pools and thermal suites.

"We've always listened to our customers and committed to innovation," says hotel director, Simon Glassbrook. "The opening of the spa and our new woodland bedrooms will see us diversify our offering and make Stanley House a genuine national destination of which are are extremely proud."

The team are hoping to see a return on investment within 12-18 months. The affluent RV sector are being targeted for day visits, as well as national and international clients who are keen followers of luxury spa breaks and the male grooming market.

This is the only spa in the north west to offer Ila products, which are 100 per cent organic and other skin care brands used are Natura Bisse, Orly nail care, Organic Glam and BeauBronz tanning.

Signature treatments include the Diamond Nature Bisse facial, exclusive to the spa and priced at £120. This anti-age treatment involves a triple massage using crushed diamond elements, which penetrate the deepest layers of the skin for optimum regeneration. This treatment is also part of the Diamond day spa package, combined with a Himalayan salt foot ritual, hydrotherapy bath, magnetic body treatment and lunch.
