Located within the expansive landscape of Teshikaga in Eastern Hokkaido, TAPKOP is an exclusive-use villa that transforms a former pension into a contemporary retreat across a 30,000-square-metre site. The spatial organisation establishes a close relationship between architecture and its surroundings. A central living space, anchored by a fireplace, opens onto the garden through large windows that frame shifting views of the mountains. This continuity between interior and exterior allows the experience of the landscape to extend into the building. The exterior is clad in Hokkaido larch with natural edges, allowing both the villa and its adjacent restaurant to sit quietly within the environment. The material’s texture and weathered character integrate the architecture into the surrounding forest while introducing warmth to the built form. This relationship continues in the bathroom, where deep green finishes reflect the tones of the Hokkaido spruce visible through the windows. Together with a private sauna and open-air bath, these spaces are designed to engage directly with the climate and atmosphere of the site. From furniture and curated objects to the surrounding landscape, the project extends beyond the building itself. TAPKOP offers a carefully composed environment that brings together architecture, material, and setting, framing a distinct experience of Eastern Hokkaido.
