Meticulously designed under the expertise of Curveline Design, the new leisure facilities, incorporating both the gym and pool hall, will see a complete overhaul of the existing spaces. With input from PRIMAL, the leading strength and fitness brand whose clients include major gym chains and top leisure clubs, such as Soho House, the Mar Hall gym will be transformed into a state-of-the-art facility.

CGI images show the new gym as an open-plan multi-functional space, with cardio machines overlooking the pool and PRIMAL Performance Series half racks, benches, and free weights.

The carefully considered gym layout offers interchangeable workout options, including small group classes and personal training sessions for both members and guests.

The work, due to begin in early March, is the first phase of the multi-million-pound redevelopment project at the five-star resort, as it seeks to reposition itself as one of Scotland’s top resorts and an international destination.

Later this year, the resort will also undergo a major overhaul of its existing spa facilities, with outline plans including the addition of an indoor/outdoor wellness suite, providing stunning views out to the River Clyde and the rolling Old-Kilpatrick hills beyond. Inspired by the sleek simplicity of Scandinavian design, the exciting plans from award winning spa designer, Curveline, are sympathetic to the listed building structure whilst modernising the spa as a luxurious, tranquil retreat for the senses, focused on wellness and wellbeing. Phase two of the refurbishment will also include a new wellness suite and spin studio.

In addition to the spa and leisure works being undertaken by Curveline, a select team of award-winning interior designers, architects and hospitality consultants has been appointed to transform Mar Hall and to take its redevelopment project forward.

Architects at Unwin Jones Partnership will work closely with the interior design team at Graven to transform the look and feel of the entire resort, while hospitality consultants, the Gorgeous Group, have been appointed to redefine the food and beverage experience for guests.

The aspiration for the resort, which has previously hosted Harry Styles, David Beckham, and Beyonce, is to rival Scottish five-star destinations such as Cameron House and Gleneagles. Early design plans centre on sympathetic restoration, capturing the essence of Mar Hall’s rich Scottish heritage, while adding a modern twist.

General manager, Joe Gallacher, said: “It is an incredibly exciting time at Mar Hall. After a period of uncertainty for our members, guests, and staff, we are now in an extremely strong position with a multi-million-pound investment that will return the entire resort to its former glory.

“Since the acquisition, we have been busy working behind the scenes making much-needed, immediate cosmetic changes to the property. We are now thrilled to be kickstarting the first phase of a very comprehensive redevelopment programme at the resort with the introduction of a new spa and leisure offering, and to be able to give our members and guests a sneak preview (the first of many) of what is to come.

“We’ve been welcoming guests back to the resort and it’s fantastic to be busy again – not only selling out rooms, but also filling our calendar with wedding bookings and other events. We look forward to inviting our members and guests to the resort to showcase the new vision for Mar Hall as we take them on this exciting journey with us.”
