The alternating narrow and wide dimensions are interlocked on the wall surface, eliminating the rigidity of regular paving. This creates a natural breathing sensation on the facade. The brick surface is an exact replication of natural stone, with the rough texture of coarse particles concealing the frosted texture of sandstone, and the brownish tones vary in depth. 

When the fingertips brush over it, one can feel the undulations of the "stone texture". When the light slants across, the fine lines of the narrow bricks will spread out into a fine sheen of light, while the thick texture of the wide bricks will solidify into a matte finish. These two layers are present on the same wall, capturing the "natural" randomness and layers in our hands.
