Different from hardness and endurance of steel and concrete, wood is alternate material. Since wood shall be replaced from time to time due to its property of decays, wood structure is in the status of continuous re-build. With the mild touch of wood material, wood structure generates live space. Current wood structure includes traditional wood cabin, frame module wood cabin and application of timber structure, wherein most are used with wood board. Plywood is the most economic material for wood board fabrication, therefore, this research tries to re-interpret the meaning of plywood from the angle of property art.
The restriction in climate and geography in Taiwan makes 52% of its forest serve as cultivating forest. Under the premise of economic development, Taiwan’s land use leaves no chance for economic forest. However, wood is not main building material in the 20th century, thus economic forest has no industrial value in Taiwan. Apart from the permanent pursuit of its hardness and endurance of buildings, it could be different thinking to make building continuously change, maintain and update. Comparing with other building materials, wood is relatively soft. Different from the large wood building which stacks many wood boards to increase strength, this study aims to make rigid structure assembles small pieces components into three-dimensional spatial unit and images its decomposability and replace ability.
When I used the laser cutter for the first time, I accidently cut the wood board into small unit components and constituted a small three-dimensional unit, and then assembled into a larger three-dimensional module to compose a space. With help of digital machines and tools, these wood structure components can be cut quickly at present, by which these complicated design unit designs can be realized. Through precise and quick cutting of laser cutter, it can easily testify the constructability of different small components. The research challenges the limitations of laser cutter and wood board in different experiments. In designing the fundamental structural unit, it controls unit size within 30cm, which can be assembled by a person independently. The composition of unit fragments can reinforce the strength of the structure. During the assemblage of unit, composition of larger three-dimensional unit can be more stable because its structure, especially for wood material which has different textile directions. In traditional wood structure, it is mostly jointed by vertical and horizontal lap, which is limited to size and span of wood material. Routine processing in traditional wood production makes wood structure less flexible in architectural design and generates common spatial form. Through the machining of laser cutter, the monolithic plywood is cut into small pieces and assembled wood structure having unique style. It can be aggregated into an integral space-frame from a bottom-up composition.
After digital small wood structure unit is composed into a larger three-dimensional structure, it keeps the original features of unit. With its essence, organism and light of meticulous wood structure, it forms aura on the site, finally to construct four small spaces on beach through four different design units, so as to discuss relationship among material, tectonic, place and poetic of space. It is expected that the research combines traditional wood structure and current digital fabrication technology to re-interpret wood material through new technology, further to develop new ideas and perspectives of wood architecture.
