Repository House is a private residence located in north Japan, Asahikawa, Hokkaido. The house was designed by Jun Igarashi Architects. The site is located on the huge countryside outskirts of Asahikawa and the house is in relationship with this landscape.
Project description: Asahikawa, summer is more than 30 degrees, and winter become -30 degrees. Here is the region that is very big difference in the temperature. So this house have only small openings and insulation performance up. A buffer zone makes a moderate relationship with the outside world. The exterior walls use pine from Hokkaido, and also structure timbers uses from a local material. I took the wooden structure because of good thermal conductivity.
Plan is surrounded by two halls (living dining/master bedroom) and washing room, which form a buffer zone. Washing room has top light and it introduces the light into the entire house. Also, it makes a diffuse light curtain.
By creating a buffer zone the thermal environment is improved, and also can connect the human psychology with the surrounding environment.
Natural environment is a great presence, but sometimes it sudden changes to a stern expression. This is the architecture designed to show the relationship between the natural environment and the indoor environment, that changes every day.
