A house built in the residential area of Setagaya-ku, right next to the parents' of the owner. While the house is open to the outside environment, it secures privacy by keeping moderate distance from the neighboring houses. The house is set at the west end of the site, and the front garden distances it from the street on the east. The garden also works as a buffer zone with the next-door parents' house. The living room, directly facing the front garden, sits at the centre of the house and connects other spaces: work room, bed room, gallery room, and terrace. All these spaces are contained in a 8.1m square base area, smoothly tied to each other both vertically and horizontally. Each space differs in effect of natural light and ceiling height to serve its own purpose. The migratory connection of these spaces would engrave a rich contrast and rhythm in life, such as stillness and motion, or light and shadow. The outdoor terrace above the kitchen is a hub of the building that connects the main living space to the rooftop both practically and visually. It also lets in outside nature like wind and light. The north side wall of the terrace works as a large reflector plate, helping the living room always filled with soft natural light.
