To enhance the competitiveness and vitality of Seoul’s downtown, the government announced a policy to expand redevelopment plans, which are the means of changes in downtown, and amend incentives to attract various redevelopment projects. The type of urban redevelopment methods had large-scale, small-scale, conservation, and mixed-use method that was recently created and expanded method to incorporate existing methods; however, a new method is required for review. The goal of this research was to propose an integrated plan to compensate for the limitations of individual development and connect each district. The distinct commercial district (Gwanchul-dong, Gwangjang market) and the old commercial district (Gwansu-dong, Dongdaemoon market) were chosen as application cases.

In conclusion, there are three institutionalization strategies. First, the introduction of the “Conservation-Connected urban redevelopment method” should have consensus, and be based on the urban redevelopment plan, so discussing its necessity. Second, to implement the concepts of "integrated conservation and redevelopment" in the project, the current system's relevant regulations must be improved. Specifically, the provisions of the "Cultural Heritage Protection Act" that allow the phenomenon of registered cultural heritages, as well as building construction and volume ratio reduction, are delegated to the local government's Ordinance except for designated heritages. Lastly, the standards of locals who use the “Conservation-Connected urban redevelopment method" development method should create specific detailed regulations.
