The brick surface is covered with fine, three-dimensional textures, resembling dark sandstone soaked in mountain mist. Each piece has an indistinct warm tone that spreads out across the wall, forming a gentle dark background color. Some have a light brown edge, just like the residual warmth of the setting sun brushing against the clay. When scattered across the wall, they do not have a mechanical regularity, but instead create a "quiet yet rhythmic" layering. 

The rich black color gains a light and airy sense of breath, when combined with the wooden balcony railings, it feels as if the texture of the forest has been incorporated into the building. It retains the authenticity of the earth while also carrying the neat rhythm of a modern space.
