garage house in hokkaido by Ryuji Yamashita
Japan-based Ryuji Yamashita Architects has completed a residential project in Hokkaido for a family of four incorporating a garage structure. As the plot is located in a low-density neighborhood in a small town named Namporo, the aim of the architects was to form a building that operates in harmony with its setting. Thus, they opted for a structure that makes the most of the surrounding nature but also fulfills the requirements of security and privacy.
The brief was to design both a house and a garage space, including storage, as the husband of the family is a vehicle enthusiast and desired a place where he could engage in his hobby in his free time. Another requirement was to be able to see the car from inside the house. To accomplish this, the architects decided to split the building into two functions — providing a separate residential and garage structure — while by aligning the two buildings, the visibility of the vehicle can be achieved from anywhere in the house.

The two volumes designed by Ryuji Yamashita Architects (see more here) share a common side, giving the impression from afar that it’s a united structure. In fact, between the two buildings, a tiny semi-outdoor courtyard is formed as a buffer space. This area is topped by a transparent roof, while thanks to its louver doors that pierce the walls, it serves as an intermediate area between the two volumes. However, all of the structures feature a separate entrance, maintaining privacy and security. By separating the functions, the cost of meeting the requirements for heat insulation and seismic performance was reduced.
During the summer, the family can enjoy a barbecue time in the courtyard, while during the cold months, the walls are wrapped with a film. Thus, the yard can double as a greenhouse space where one can enjoy the nature of Namporo. By doing this, the interior spaces can be ventilated with the circulated warm air trapped in the greenhouse space, whereby an energy-saving effect can be expected. Apart from the ventilation flow through the interior, the buffer area allows natural light to penetrate the interior, generating a well-lit and intimate environment.
