The two most important pillars of architecture, space and material, are also the two most cooperative and antagonistic forces in architecture. After the war, due to the maturity and mainstreaming of concrete and steel technology, architects have paid more attention on the development of space theory instead of the research and investment in material construction, this has led to the marginalization of material theory and development in design course. However, space and perception theory require material manipulation techniques to advance architecture. Material technology contains many aspects, such as the balance between performance and aesthetics, or maximization of architectural engineering efficiency from Buckminster Fuller’s theory. The currently popular digital design and fabrication is also a model for the transition from design theory to material operation technology. Craft technology needs to be translated through architectural engineering to truly become the reality of architecture and meet the practical value of architectural standard. Following the concept mentioned above, students design the system prototype according to the material and the construction methodology serving as the basis for design operation and research, and then gradually goes up to match the overall function, context, and phenomenon. The course knowledge requires the architectural system and detailed practice, and transfer to the design aiming two major focus, Interface and Composition. This training methodology focuses on highlighting the role of the prototype design in order to simplify the operation conditions and students could explore profound mechanism between building systems and architectural theories.
