This is a private residence located on Hokkaido, an island to the north of Japan. The site is in the huge countryside outskirts of Asahikawa.
In this region, temperatures reach a huge range: summer is more than 30 degrees [Celsius], and winter can become -30 degrees [Celsius]. Therefore, this house includes small openings and high-performance insulation. The exterior walls are constructed of Hokkaido pine, and the structure is also made of local material. I decided on a wooden structure because of the material's good thermal conductivity.
The plan surrounds the two halls (living/dining space and master bedroom) and the washroom with smaller rooms that form a "buffer zone." Skylights introduce light to the entire house, while curtains are used to diffuse the light.
The buffer zone improves the thermal environment within the home, and also moderates the psychological relationship with the surrounding outside world. The natural environment is a great presence, but it can change suddenly, This architecture is rethinking the ever-changing relationship between the natural environment and the indoor environment.
