As the inside space is in full view from surrounding tall buildings merely with transparent toplight, the decision was firm from the beginning to install the ceiling under the toplight. Through the installation of the ceiling to make it possible to delicately feel the change and expression of the sky through it rather than directly looking up, coming up with an idea how to configure the indoor space to sufficiently acquire the feeling of outside expression became a focus of attention. When it comes to the ceiling, it is a white acrylic vault board ceiling enabling the projection of the subdued expression of light and sky coming through glass toplight on the ceiling surface. In addition to the mortar floor and larch plywood wall, the concrete white acrylic surface of high visibility is deprived of its concrete existence by its detailed treatment as if there is no brick mold. In doing so, the surface loses its concrete existence and acquires its abstractness as if only the light and expression appear at the upside of the inside space.
