7132 House of Architects

The House of Architects is a hotel in Vals built with contributions from four architects: Peter Zumthor, Tadao Ando, Kengo Kuma, and Thom Mayne. The property has 73 rooms, each just 20 square meters, and leans into contemporary design rather than conventional hotel comfort.

The spa side includes a relaxation lounge, a thermal pool, and outdoor baths. It's positioned as an adults-only, couples-friendly space, and access is restricted to hotel guests rather than day visitors. Given the price tier, this is a high-end stay rather than a budget option, and the focus is on the architecture and thermal bathing experience rather than a long menu of treatments.

Getting there can be part of the experience too: the hotel offers private transfer by limousine or helicopter (an Airbus EC 130) for guests who want to skip the standard drive into the valley. Staff communicate in German and English.

This isn't a drop-in day spa. If you're after a Vals thermal bath experience without booking a room, you'll want to look at other options in the area, since this one is tied to an overnight stay. For exact rates, room availability, and what's included with the thermal pool access, contact the hotel directly.
