This study will focus on the rehabilitation of the boundary space where apartment complex, commercial buildings and existing underground infrastructure intersect, by applying Facade-Poche, which recognizes architecture and city as integrated space. This area has strong possibilities that is to satisfy the user and anonymous pedestrian needs through the designated spatial territory that different types of urban fragments meet. 'The boundary space' is defined as the linkage between existing underground infrastructure and commercial buildings above ground as well as the privately owned public space between street stores and apartment complex. Despite quantitative expansion of public space, the lack of link system and entrance with existing facilities and illegally use caused disconnection of pedestrian flow and circulation. This study will propose a design guideline to improve current institutional framework and effectively manage the privately owned public space, with installation architecture which is flexible and temporally occupied depending on user's purpose.
