Rockliffe Hall in Hurworth said the development within its grounds will further enhance its award-winning spa facilities when it opens in the autumn.
Work on the 200 metre square spa garden is now underway, with local contractors Wharton Construction appointed to manage the project.
The new Spa Garden will be adjacent to the current spa and will have two outdoor hot pools including an infinity edge hydrotherapy pool with massage features and a warm Jacuzzi, under-floor heated decking and lounging areas.
It will also feature a garden room with a traditional glass-fronted sauna cabin, fire pit, water feature, landscaped gardens with views across Rockliffe Hall’s grounds and heated relaxation loungers.
Liz Holmes, spa director at Rockliffe Hall, said: “This is a major development for Rockliffe Hall. The Spa Garden will really make the resort the go-to place in the North of England as it is going to be the only one of its kind. The new development will overlook Rockliffe Hall’s magnificent grounds and offer even more luxury within the 365 acre estate.”
Holmes confirmed her team is now developing a range of new treatments, spa days and promotions, working with high profile brands to introduce new experiences for the launch of the Spa Garden.
Rockliffe Hall’s spa is one of the most successful in the UK and has won a string of local and national awards despite only opening five years ago.
