The study has started with the backgrounds such as followings. First, the urban problems arising from the residential areas under the current zoning system are (1) high density urban development which is disregard of district conditions (2) housing supply without considering the quality of living environment. Second, the Architecture and Construction Code allows the maximum of 400% in FAR(floor area ratio) in residential zones. However, the development pattern is in reality far short of the allowance. This suggests the necessity of lowering the statutory ratio. The purpose of this study is to investigate Classified Zoning Control(Down-Zoning) in residential zone appropriate to the level of current development density patterns in Seoul. So this research analyzed the factor of actually Realized FAR of the lot in residential zone in Seoul.
