Complex is a minimalist house located in Shiga, Japan, designed by FORM | Kouichi Kimura Architects. The building is located along an arterial road with heavy traffic. The surrounding area is full of commercial facilities and condos. It was designed as an office building for a corporation, and consists of four layers including the garage on the first floor, the office on the second floor, and the guest house on the third and fourth floors. The solid walls of the façade are finished with rough steel plates, which enhance massiveness of the building. Meanwhile, the elaborately designed positions of the openings create the light appearance.
