Text description provided by the architects. The project is a renovation of residential unit of an apartment in Kyoto, Japan. A three dimensional ceiling is designed to affect the perception of space and human physicality.
The ceiling height changes gradually, from 2.63m at the living and dining room, to only 1.67m at the Japanese-style tearoom located in the deepest area. This lowest ceiling height is defined by human heights, and other three points were designed as high as possible in the limited existing structure. The geometry of the ceiling resembles to that of shell structure, and it gives feelings, even within a small residential unit, that your body becomes bigger/smaller. The perspectives in this house create the perception of physical extension and contraction.
Round-shaped lightings are placed on the warping ceiling. They have all different sizes, from 300mm to 1500mm radius, and cast indirect lights reflected by the mirror embedded, creating the effect of erasing the ceiling edges. It also makes the feeling that you have another space above the ceiling.
Ceilings and lightings are generally unconscious part of human perception. But this small intervention enhances your physical perception thus the richness of life.
