The new thermal spa, Thermes de Royat, is located in the heart of the city of Royat on an urban infill lot along a tree-lined street near a green mall. Inside, the spa includes changing rooms and two circular pools — one for resting and relaxing and the other for aerobic activities led by a therapist. The pools are naturally fed with thermal hot spring water, which is about as eco-friendly as it gets. Therapist-lead regular sessions with spa goers help improve cardiovascular health as well as rheumatism.

Stilts hold the entire spa and pools up off the ground, making the stainless steel pools level with the street. The entire facility is covered in a wood louvered facade, but not closed off from the outside environment. A large living wall covers the wooden facade with a giant green wave, protecting the interior and creating a micro climate in the urban space. In the summer, the living wall helps ventilate and keep the spa cool, while in the winter the green mass helps insulate the space. A large skylight and tall windows provide natural daylighting for the space.
