The purpose of this study is to analyze the distribution of the building area and find the characteristics of development density where the areas to perform special functions as residential, commercial, and business area in Seoul. As a result of classification of the regions with the component ratio of building area ratio by types, the greater part of Seoul is residential areas and only a small part of Seoul have business function. Contrary to the Kang-Nam business districts, the central business districts have few or no houses. It is concerned that the redevelopment projects, such as New-Town, make Seoul more high-density. The industrial area lost the attractiveness as a resident in spite of businesses or infrastructures. So the industrial area will be the best place for reduce journey-to-work distance if improve housing conditions. As well as management of density, management of use is also required for effective landuse and green-growth city.■ keyword :|Landuse Characteristics|Building Area|Development Density|

Korea is implementing housing support programs such as public rental housing and housing allowances to improve the housing welfare of low-income households. In this study, we empirically analyzed the effects of the public rental housing program and the housing allowance program on residential satisfaction and the housing cost burden of policy beneficiaries. In accordance with household attributes, we analyzed how the status of using these programs affected each group’s residential satisfaction and housing cost burden. We used the data from the 2020 Korea Housing Survey conducted by the Ministry of Land, Infrastructure and Transport. We examined the housing support programs’ effects on each of the following household groups: all households, one-person households, households of newlywed couples, young adult households, and households of the elderly. The status of residing in public rental housing positively affected the residential satisfaction among all households, one-person households, and households of the elderly. It reduced the housing cost burden for all household types. The status of receiving the housing allowance negatively affected the residential satisfaction for all households and increased the housing cost burden for young adult households. We present policy implications for future housing support programs based on the findings.

The designation parking-only building (POB)was first introduced in the Parking Lot Act on 14 December 1991. According to the law, POBs can be used for purposes other than parking facilities, that is, non-parking facilities (NPFs), up to 70% of the total floor area. In addition, the POB is an infrastructure in accordance with the National Land Planning and Utilization Act. Excessive introduction of NPFs in a POB weakens the public nature of the building and creates additional demand for parking due to NPFs, thus changing the original meaning of a parking lot. However, on the other hand, NPFs in POBs have a positive aspect in that they contribute to the realization of a compressed city through mixed-use development and increased user convenience. This study investigated and analyzed the usage status of NPFs for POBs in 31 cities in Gyeonggi-do, Korea. In addition, the amount of traffic generated by NPFs was defined as the traffic inducement rate (TIR) and policy implications were presented by analyzing the influencing factors. The ratio of NPFs in POBs was 20% on average, but 3% in public parking lots, and 24% in private parking lots. Most of the NPFs used were for-profit facilities such as neighborhood living facilities and sales facilities. As a result of analyzing the factors affecting the TIR, it was analyzed that the larger the total floor area of a POB, the higher the private ownership, the smaller the number of parking spaces; and the larger the entrance road width, the greater the TIR. In order to prevent excessive change in the use of POBs, the ratio limit of NPFs will be gradually lowered in proportion to the total floor area and public parking lots will be expanded. In the planning stage, meticulous district-wide planning is required for the use and ratio of NPFs in POBs according to the access road type. This article will be meaningful if you want to supply a POB that satisfies suppliers, consumers, and users. In particular, it will enable government officials who decide and implement policies related to POBs to recognize that full-scale research is necessary.
