It is located in a quiet residential area of Kobe city at the foot of the Rokko Mountains. It is in the middle of the scenery where houses are layered towards Mt. Rokko. Previously, it is based on the masonry retaining wall which was a terraced fields. Due to the effect of the terraced fields, the sunshine is good and there are many houses in the shape opened to the south (sea side), so irregular houses are lining up, there is a certain homogeneity.

To build this house here, first set the inner wall oblique to the light on the south side (sea side), and tilted the axis of the wall at 45 degrees.The outer wall is an elongated rectangle in the east and west according to the site shape, and it is a form which encloses once with a wall extending to 45 degrees with a frontage of 5.8 m and a depth of 13 m. As a result, the depth of only 5.8 m to the south opening becomes obliquely about 8.2 m, so the light gradation appears more clearly. Also, due to the wall inclined at 45 degrees, the light crosses from the east to the west due to the difference in the depth of the space and the change in the material, it blends and felt the dimensions of the light over multidimensional. In addition, a migratory plan creates a sensible depth to various directions.

小巷 – 住宅与工作室之间 | ALLEY (DOMA) – BETWEEN RESIDENCE AND ATELIER
The most important consideration in this plan is the distance between the residence and the atelier. In order to make the distance as an architecture, we set up an alley (doma) as a semi-public space inside. At the first floor near the front road is the atelier with high publicity, the privacy goes higher as going to the back of the second floor. The alley connects to the road via the courtyard as the staircase that connects the atelier from the second floor residence, the street connected from the courtyard to the entrance, and the external approach. The floor height on the second floor is lengthened to take the distance between the atelier and the residence, and the spaces A and B there between change according to the form of the family and the situation of the atelier. In the alley, green is planted, windows are opened from each room, they are connected three-dimensionally, and the residence and the atelier enable both the physical distance and the sensible distance by alley (doma).

结构 | STRUCTURE
The structure covered this house with the basic structure of the outer wall and roof that encloses the wall at the axis of 45 degrees. For that reason, by using a truss structure for the large roofing beam which tends to have a large cross section, it was made up of small diameter members and realized the lightness which suited the scale of indoor life. Roof structure of truss structure with three hinges by small diameter member. A truss was assembled with a small diameter member so as to lightly make a hut group covering the main space on the second floor with no columns.

Fulcrums on both sides of the truss are supported by a horizontal beam that resists the thrust to form a 3 point hinge truss structure. Thereby it is possible to eliminate the flat beams, it was to open the space below the truss. Three point hinge structure is advantageous in that no additional stress is generated even when the horizontal beam expands outward due to thrust and aging and the fulcrum distance becomes long. It is a less stressful mechanism for the hut group with this delicate small diameter member. In addition, the hinge part of the apex makes it possible to divide the truss into two parts, and each part is unitized and carried in and carried out to reduce labor saving of construction.

材料 | MATERIAL
Where no finishing material is required, the wall was basically based on exposing the studs and braces as it is. For example, the inside alley side has walls finished as outer walls, the atelier side is not finished and the outer wall surrounding the 45 degree wall is finished with white paint. By using a heat shielding sheet on the walls of the spaces A and B facing the courtyard, the space of the virtual image gained more depth by blurring the space.

In addition, the wall between the Japanese-style room and the living room was mixed with the clay of the local tile of the husband and the clay taken at the time of foundation construction to make up the ground wall, and the door knob and the nameplate were baked in the same fog silver as the tile. The wall of the space A used a veneer of apple from which the child’s name came. Translucent polycarbonate corrugated board was used for the wall that straddles the room. In the daytime, light was gently transmitted, and in the night lighting was added to make light walls. The floor adopted a lot of cypresses of the local Rokko Mountain and adopted plywood imported in Kobe. I aimed for a house with a lot of people involved in my life using as much as possible face-visible materials.
