The "Passing of time" includes the landscape outside the window, the flowing lines of the interior, and the rare stone skin material to create a space that fully expresses its tolerance and uniqueness. For the color combinations, materials and colors expressing the serene feelings are selected, and, in particular, the stone skin is used as the vertical vision of the wall. In the spatial dimension, the bright marble is used as the flow in the bottom of the space; also, the black lines of the ceiling modify the beam column, extending to the overlooking view outside the window.
