Analysis of Parcel Characteristics That Influence Realized Floor Area Ratio by Housing Type

초록

Land use and density in a city are shaped by various factors, such as regulations, urban structure, and the characteristics of individual land parcels. As a management measure, legal floor area ratios are stipulated. However, not all land parcels achieve the legal floor-area ratio, and the average achieved floor-area ratio (A-FAR) is approximately 70% in Seoul. Because most cities have fairly high proportions of residential areas, land management is important. Hence, to supply and manage a variety of houses classified into different residence types, it is important to identify the characteristics that affect their development. Therefore, the aim of this study was to identify the land parcel characteristics that affected realization of the legal floor area ratio based on housing type. A-FAR confirmed that Multi-family houses type were higher than Detached houses type. It was found that the parcel area of housing types, excluding Multi-household houses and apartments, had a non-linear relationship with A-FAR. The A-FAR increased for apartments and City-typed houses situated on relatively wide roads, and all types of houses, except for apartments, had positive effects on the A-FAR when their numbers of frontages were large
