This is a renovation of the second floor of a 30-year-old housing. The existing L-shaped LDK has windows on four sides, a green road on the east side, and a vacant lot on the west side, so it has the potential to be bright and breezy, but it was not functioning well due to the distance from the facility on the east side and the overflow of things around the window. Therefore, we decided to divide the one-room LDK into a central hall space and supporting sub-rooms and storage areas, and to reconstruct the relationship between the interior and the exterior.

 First, we drew a diagonal dividing line that would open up on the front road side. With the diagonal dividing line as the starting point, the L-shaped space becomes a collection of irregular spaces, with the hall space in the center and various depths between the surrounding sub-rooms. A large kitchen room open to the northwest, a study room with a TV and storage space for books, a stateroom, and a laundry room that serves as a buffer to the sunroom (balcony) are all finished in different materials and colors. The shape of the hall can be changed in several ways. The upper part of the doors also functions as a continuous display shelf. The shape of the hall is a combination of two right-angled triangles, and the flooring and ceiling paneling are placed in the diagonal direction of the triangles to weaken the axis of the existing building, and to create an equivalent relationship from the hall to the sub-rooms and outsides.

 The one room, which is divided and connected by air, creates a more generous environment by redefining the way it expands and its range, and gives a new openness to life.
