We use domestically produced cypress and cedar for the pillars, red pine for the beams, and core cypress material for the foundation. The standard wall finish is a plaster finish without wallpaper. The characteristics of the plaster include excellent moisture regulation, resistance to seasonal changes, and difficulty for mold to grow. Additionally, we use other natural materials such as washi paper and stone, focusing on creating wooden homes that are gentle for the residents.
