Research on optimum function and utilization of oceanic architectures for marine space use case study on Kyushu Region, Japan

Recently, the demanding for effective utilization of marine spaces in forms of oceanic architectures has been rising high by new social requirements as well as other constructions, and the like. Consequently, architecutural characteristics and structural effectiveness of them should be reevaluated accordingly. Objects of this study are four architectures located in the shallow area of sea around Kyushu Region,namely Marizon, Genkai Sea Hot Spring Palea, Marine Aquarium Sea Doughnut, and Akasaki Elementary School. Their functions, structures, setting forms, then conditions for situating buidings, processes of construction at sea, and challenges after construction had been clarified by our literature survey, the hearing investigation and the field research. Our results are as following. Functionally, each above architectures has respective facilities to fully utlize regional marine resources and environment, etc.; Structurally, all of them had premeditated both the bad conditions of coastal environment and providing spaces for water activities. In terms of their construction processes at sea, factors blow had been carefully considered before being sited: limitations of local spatial scale, full utilization of local environmental conditions, measures against disadvantages of sites, the particularities of regional nature, environment, and society. In conclusion, our findings suggest that planning of the oceanic architecuture should combine the usage, the fuction, and the understructures well with its marine conditions.
