Kouzan Woods is a carefully designed 145m2, two-story cabin for vacation and skiing. Located in a protected zone of Niseko, Hokkaido, Japan, the site is surrounded by a scenic and colorful forest that changes throughout the four seasons. As both the design architect and the developer, our goal is to achieve harmony between nature and leisure. To achieve this, we embraced a minimalist approach with a simple gable roof and floor-to-ceiling glass, which minimizes the cabin's impact on the neighbourhood and seamlessly blends the boundary between the indoor and outdoor spaces. This approach creates a vessel that captures the beauty of the local weather and nature while providing comfort for those seeking relaxation and tranquility during their vacation.
