The improvement in quality of life and regeneration of local communities are increasingly recognized as important social problems. In this situation, the systematic management and continuous improvement of public space are acutely needed as a strategy for environmental development of old urban areas. The aim of this research is to provide methods of establishing a master plan for public space as an alternative proposal against the absence of spatial plan and systematic strategy in the area of construction, use and management of urban public space.
In order to promote the project of public space successfully, first and foremost, the systematic management and continuous improvement of public space are essential. It is possible to perform an important role to suggest basic direction for local revitalization and urban revitalization. As a method for this investigation, the master plan for public space could be a rough sketch for how public space in a
specific area can be constructed and managed. The roles of a master plan for public space could be divided into the method for design, the method for communication and the method for space management. In addition, it is not only a design method to express and explain basic directions, concepts and guidelines of public space through texts, drawings and images after analyzing local conditions but also involves a communication method to negotiate with multiple stakeholders.
