The new structure is located on the southeast side of the façade, in a position symmetrical to the swimming pool. Like the pool, this is also detached from the main building: the platform hovers 15 meters above the ground and is supported by two pillars clad in larch logs, similar to those that punctuate the façade behind. Visitors reach the wellbeing area via a suspended walkway, which at the same time opens up to the newly constructed relaxation area, offering space for up to 27 people. On the platform, individual microstructures with gabled roofs accommodate the functional programme on two levels. A surprising element is the lower level, where the horizon undergoes a 180° rotation, and the huts appear to be anchored upside down.

The two levels are characterised by a different treatment of privacy, with mainly exposed spaces above and protected spaces below. On the upper floor are two whirlpool baths, two panoramic showers and a changing room. The lower floor is a textile-free area: the central, enclosed part houses the foyer. From here one has access to the soft sauna, the Finnish sauna, a shower cabin, an ice mist shower and a third outdoor pool, from where one's gaze can sweep over the surrounding landscape.

The decision to work with inverted pitched roofs is a choice motivated by formal and functional reasons: on the one hand, the desire to reproduce the architecture of a mountain village, and on the other hand, the practical need to allocate in the inverted roof the water purification system in the case of the swimming pool and the seating tiers in the case of the sauna. Moreover, the offset of the huts and the alternating orientation of the roof ridges allow a 360° view of the landscape, the real centrepiece of the project.
