suppose design office brings cavernous baths to NOT A HOTEL NASU CAVE

not a hotel nasu cave in Tochigi faces farmlands

NOT A HOTEL reveals its latest hospitality concept signed by architecture group Suppose Design Office in Japan‘s Tochigi prefecture. Dubbed NASU CAVE, the project emerges from a natural plateau and spans three floors, offering almost panoramic views of a garden that connects to the sky and a big ranch raising horses just ahead. Amenities at the pet-friendly property include three private bedrooms, a cavernous bath experience, a sauna, an infinity pool, a living-dining room, a terrace, and a hot spring.

cave-like bath and hot spring by suppose design office

NOT A HOTEL NASU CAVE (see more here) features a cavernous cold bath, drenched in darkness, where visitors can enjoy a moment of calm while gazing at the water’s flickering surface. Complementing the cave-like experience is a glass-enclosed sauna filled with sunlight and framing the outdoor scenery and, just outside, an infinity pool spanning nine meters in width, surrounded by trees. Moving to the more private areas, the team at Suppose Design Office includes an equally cavernous hot spring tucked inside a bathroom, with a wide view towards the ranch.

The architects maintain that level of privacy and comfort across all three bedrooms without taking away the immersion in generous daylight and natural vistas from the farmland surroundings; one of these rooms even includes slanted windows, through which a star-filled sky can lull you to sleep. Reurning to the more social areas, the building hosts a second-floor outdoor terrace with a fireplace, immediately accessible from the living-dining room lined with a sliding door that brings the outdoors in. Up to six guests can occupy the spaces.

Material-wise, Suppose Design Office coats the exterior and interior walls of NOT A HOTEL NASU CAVE with Moltex, which is carefully handcrafted to create an uneven texture across the entire structure, built from reinforced concrete (RC). ‘This unevenness gives the building an exquisite presence that blends in with the surrounding scenery despite being manmade. The change in color over time is also one of the joys of owning a house,’ concludes the hospitality group.
