Mountain House is a minimalist residence located in Hyogo, Japan, designed by Hiroki + Tomoko Sekiguchi Architects. The two requirements from the client were to have enough space to park a large four-wheel drive car, and not to be bothered by neighbor’s gaze while relaxing in the house. In order to fit the large four-wheel drive car in the small site of only 27 square metre, the plan was to utilize legal maximum floor space, which lead to build the walls as close to the neighbors as possible. The inclined walls are to ease the eyes of an oppressive closely built house.
