The walls, floor, and ceiling are finished with glass, and three slit-like gaps have been created to let in light while ensuring privacy. The ceiling height of the basement floor is 4 meters high, while the second and third floors are kept at 2.2 meters to allow light to penetrate the slits to the basement floor. The rough-finished walls on the north and south sides of the building, which extend from the first to third floors, softly diffuse the light when illuminated, and serve as a surface light source.
