The interior design of the orthodontic clinic in the building in the center of Kumamoto city. We aimed to create a private room that is bright and open, yet gives privacy and a sense of security. On a flat surface, the patient area and staff area are clearly separated from the reception area to ensure functionality, and the patient area is a continuous soft space surrounded by a wooden wall with rounded corners. did. Each space has holes made as needed, which serve as doorways, windows, storage, etc. In this way, while clarifying the area and ensuring privacy, it creates an open impression that allows you to see far away. Soft light from indirect lighting falls from the holes in the ceiling, but by changing the color of the light, the impression of each space is changed little by little. We believe that a small-scale space that changes and connects will create a sense of distance and give the guests comfort.
