Characteristics and Retrofit Constraints of Grayfield in Korean Cities

Abstract

The purpose of this study is to analyze the characteristics and the retrofit constraints of grayfield in Korea and to suggest ways to revitalize them. To do this, we firstly classify grayfields according to the variables of development level and site location through factor and cluster analysis. Secondly, we found that strong improvement and land use change are the factors to vitalize grayfields through an independent t-test. Thirdly, we analyze the factors that affect the revitalized project in order to derive the retrofit constraints. As a result of the analysis, we suggest that the government take steps to lift regulations to encourage complex development, provide administrative and fiscal support for demolition costs, and deal with ownership-related issues. The government also needs to monitor the private sector’s stable operation and request private sector’s support for the local community and a public transport-oriented development method for the revitalization of the site as well as carbon reduction.
