- A House with Self-Standing Wall -
Situated in a calm residential area of Setagaya, Tokyo, the rectangular house faces southward, with a garden at the rear. Several meters in front of the house, a concrete wall has been constructed to provide sufficient privacy to the glass-façade house, while retaining a sense of openness.
The wall functions in three different ways. First and foremost, it impedes the line of sight from the street. Secondly, it acts as a gate to the residential area. The gate, a human scale opening in the wall, is reminiscent of the entrance to a traditional Japanese tearoom. And thirdly, the space between the wall and the house creates an open porch which can be used in private.
The area in front of the wall is paved with concrete for use as a parking space. Several slabs protrude at different heights to create barriers, whilst a separate section offers weather protection for bicycles.
From inside the house, the residents can enjoy the views of both the porch to the south, and the garden to the north. With no partition on the first floor, there is a constant feeling of openness. The house receives natural light from various sources throughout the day: direct sun light from the south; gentle, diffused light from the north; and light entering through a square opening in the ceiling. The nature of the three types of light that enter the space is changing constantly throughout the day.
