This is a renovation of a wooden house built in 1976, located at the corner of a back alley that leads to a shopping street. The existing buildings consisted of two parts: an office and a residence. The office’s facade faced the street and was unattractive through its sloppy composition of rooms and abrupt condition. The client is an artist who required a comfortable living space, a space for creation, and an exhibition space of her works. Additionally, the renovation of the office’s facade was requested.
Under the difficult conditions of structure and cost, the architects considered how the space should connect and separate while providing enough natural light to the inside space without adding new windows. After unnecessary walls were removed, the direction of natural light was confirmed. A new layout with enough storage was implemented, flexible circulation was incorporated, and a rational lighting plan was designed. Secondly, an oblique wall was installed in the center part, with a corridor beside it; the wall giving a deep impression of depth. In addition, it narrows the soft natural light from the south side, amplifying the intensity of it with the inside space.
An opening door has detail similar to the storage core installed in the middle of the corridor, which acts as service circulation to the kitchen. A staircase is extended so as to be perpendicular, and an amphidromous flow space is provided. The south-facing part was converted from Japanese-style rooms to one large room that is white and minimal. It is used as a living, dining, and Japanese-style room, with various prepared lighting patterns.This space relates to a Japanese-style room through a rectangular opening, and is used for exhibitions, storage, etc. A space that had once been used as a traditional alcove and Buddhist altar, this new alcove space and Japanese-style room are separated with an altar and small walls which are cut off at the acute angle edge.
Slits of various widths are provided in the ceiling for installed indirect lighting. Additionally, the linen room has no window, so a vertical slit is bored into the wall to lead the natural light from the south. Opening doors have an appearance as freestanding plates by keeping the gap away from the wall surface.
The design brings the movement and various expressions of life into the white space with the inorganic atmosphere, making the space rich. Delicate details and simplicity highlight the impression of carefully chosen materials and the expression of light.
