Abstract
This study is about the architectural publicness of cost guard substation located in Busan's fishing port. The development of cities are causing fishing villages to be included in cities, and the phenomenon of being neglected or killed in functional incongruity is being witnessed. In this situation, interest in the ocean is increasing due to the increase in individual leisure time, and it is attracting attention as a center of marine tourism. In line with this, the government is pushing ahead with its fishing port development policy, but discussions on qualitative improvement and understanding of public services and public spaces have not been made due to the plan focused on aesthetic aspects and programs. Therefore, this study attempts to analyze and evaluate the Busan cost guard substation from the perspective of the 'architectural publicness' discussed in fishing ports. Analyzing cost guard substation by dividing them into internal and external public elements, and discuss how to implement architectural publicness from the wide context to the elements of interior space. Based on this, the purpose of the study is to make suggestions on how to implement future-oriented publicness, and this study is meaningful in that it looked at public buildings in Busan from the perspective of architectural publicness.
