Characteristics and Retrofit Constraints of Grayfield in Korean Cities
Jun-Won Seo and Joo-Lim Lee
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 a ect 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.
