Surrounded by the sea, the southern coastal regions of Taiwan often suffered from the water disasters such as ground subsidence, sea-water intrusion and sea level rise, so it is rather urgent to solve the problems. Under such circumstance, this research attempts to work out a symbiotic and adaptive design strategy (including the architecture and the city) and construction approach to solve the space problem of Taiwan’s southern coastal cities in front of the water disasters.
Based on Alexander’s adaptation theory and Kisho Kurokawa’s philosophy of symbiosis, this research sorts out the three mechanisms to respond to the water disasters through the case studies, including amphibious, floating and movable buildings. Besides, the properties of bamboo make it the primary material to cope with the water disasters. Inspired by the project “The Landscape of the Boundary - Material-line” of Sensation”, relevant cases and interviews with the architects, we decide to build a floating architecture of bamboo tectonics.
We select ChengLong Village of Yunlin County as the base to approach the study. From the studies on the water disasters occurring at the base, we conducted four different designs on the four timeliness (construction, structure, space and industry), which include: (1) research and analysis of types of local industries; (2) the process of water intrusion and the relationship of space transfer in the urban area after being affected by the water disasters; (3) through the bamboo system of modular matrix, it allows the users to adapt themselves along with the different environments, and thus symbiosis with the nature can be generated through the adaptive architecture.
The floating architecture built in the paper can make adaptation and symbiosis according to the different timeliness. For example, it provides the symbiosis between the residents and water disasters in the industries and life; by using the matrix structural system, it makes the space more adaptive; through the bamboo materials that the local people are familiar with and the simple tectonic method, it makes the architectures more applicable to local residents. The subsequent researches cover the replaceability of timeliness in material and structures, as well as the dynamic response of industrial development in front of the time change.
