This imitation stone brick that spreads from the exterior wall into the interior is a poetic line embodying the "coexistence of inside and outside" concept in Japanese residences. The brick surface is covered with the rough texture of gravel rocks. The exterior wall outside the glass door, using the same brick type, faces the sunlight and diffuses a cold texture. The warm and cold light from inside and outside makes the brick surface become the "transition zone of texture" of the space. 

The wind brushes past the green plants inside the room. When the leaf shadows fall on the brick wall, this faux-stone finish becomes a canvas of light and shadow - it not only inherits the natural charm of the courtyard but also wraps around the warm and cozy atmosphere of the interior, blending "roughness" and "fineness" into the tranquility of a Japanese-style residence.
