순환적인 재건축을 위한 개발밀도 추정연구

The purpose of this study is to formulate proper Floor Area Ratios for the repeatable redevelopment of apartment complexes. In general, the current housing redevelopments in Seoul have been executed in the apartment complexes with high land-value and low-density. Therefore, it is difficult that the areas with low land-value and high-density can not be reconstructed unless there are any subsidies. If they are to be left alone without going through the redevelopment process, they can easily become slums. Once, an apartment complex with low land-value and low-density is redeveloped into a high-density complex, and then it will have difficulties to be redeveloped when it becomes old and blighted. So, there is a need for a method to prevent residential areas designated for redevelopment from becoming slums in the future. We have analyzed the effect-factors of reconstruction and compared the correlations with all the factors after reviewing the reconstruction conditions on theoretical bases. On the basis of the analysis, we also analyzed the feasibility of reconstruction by types and established a FAR formula. With this, the proper FAR can be calculated at the base of land-value and zoning regulation, and the possibility of repeatable redevelopments can be predicted.
