South Lodge Hotel in Horsham, UK, has opened its new spa, The Spa at South Lodge, following a £14m (US$18.5m, €16.4m) investment.

The spa – which is owned and operated by Exclusive Hotels & Venues – is located inside a standalone building overlooking the South Downs. It was designed to embrace its surroundings, blurring the distinction between inside and outside and was created by architecture firm Felce & Guy, while creative design studio Sparcstudio developed the concept and interior design.

Sparcstudio worked closely with Felce & Guy on the building and the interior experience, developing a "rich design story inspired by South Lodge's botanical history". The result is a contemporary space that embraces its surrounding environment, whilst richly textured materials are designed to create a sense of comfort and relaxation throughout.

The spa boasts 14 nature-themed therapy rooms, juniper-infused sauna, herbal steam room, salt steam room, two swimming pools and the UK's first heated natural swimming pool. Other facilities include a gym outfitted with Technogym equipment, spin studio, holistic yoga and Pilates studio, nail salon, barber and male grooming bar.

Omorovizca – a Hungarian brand specialising in mineral-rich products inspired by the Budapest's thermal baths – has supplied The Spa's products, alongside its own exclusive bespoke product range.

The spa also features Botanica – a restaurant offering food options using fresh ingredients sourced locally from the South Downs.

Danny Pecorelli, managing director of Exclusive Hotels & Venues, spoke about the collaboration with Sparcstudio: "It boils down to comfort in their understanding of the brief and their knowledge of the project. Exclusive Hotels is all about attention to detail and so is Sparcstudio.

"I'm genuinely above and beyond delighted with the end result of the project working with Sparcstudio and the attention to detail."
