Barnfield Construction has been appointed to deliver the latest phase of development work at Stanley House Hotel in Mellor, Lancashire.
Plans include the construction of a new three-storey spa and hotel building to complement the architecture of the main Grade II-listed property, which was restored in 2003.
The wing will comprise a sauna and steamroom; a hydrotherapy pool; five treatment rooms; a relaxation room with terrace; a dry floatation room; and a manicure/pedicure room.
A gymnasium; changing facilities; and 18 individually-themed bedrooms will also form part of the new building, with a lake to be created to the rear of the spa.
Stanley House Hotel director Simon Glassbrook said: "With the additional rooms and first class spa facilities, Stanley House Hotel can be rightfully classed as a true leisure destination for the north.
"We are making a substantial investment in challenging times which highlights our confidence in the hotel, our team and the region."
