This research exhibits a novel construction method for Freeform surfaces with plywood, without using metal joints and bending. By introducing the perspective of Japanese Tsugite-Shiguchi, the research aims for a drastic change from node-oriented thinking to module-oriented thinking. This paper focuses on the investigation of how to simplify fabrication processes, how to realize the environmental capabilities of Freeform wood structures, and how to provide redundancy and stability to the whole architectural system. In order to challenge these problems, we examined three discretion methods. As a result, we have been successful to produce a double-layered surface, filled with triangular mesh, implemented only by cutting one sheet of plywood. Moreover, the system has also acquired a new nature: local-reconfigurability, wherein it can react and adapt to fit local parameters and requirements.
