Suppose Design has turned a 40-year-old home in Japan’s Fukue Island into a three-room hotel by cutting straight into the building’s concrete shell.

The studio says it was keen to work with the existing structure, rather than starting anew, and used its ‘carving’ method to connect the inside and outside of the hotel. Roughly hewn windows are fringed by tropical greenery, while doorways open onto outdoor terraces set with concrete furniture and planters.

As you’d expect, concrete also dominates the interiors of Hotel Sou, however Supposed Design has softened the effect with pale wood furniture and rattan screens.

The indoor-outdoor boundaries are further blurred with the placement of the Japanese hotel’s showers and baths, which are located close to windows and surrounded by plantlife. Sliding glass doors shut out the sounds of whistling ships from the nearby harbour. Rooms start at £140.
