The design and construction of structural units and organizational systems are discussed from the point of material and construction for the design and construction of linear wooden structures.

Through the extraction, evolution, alienation of structural units, and the expansion of the organizational system, this project aims to advocate a concept that the material and structure of construction should be determined at the beginning of design, rather than the concept or shape of architecture. From the bottom-up angle, we need to use the design to help the people and solve the problem.
