As the aging of domestic apartment houses intensifies, remodeling to improve the existing residential environment and improve the quality of housing is becoming an important maintenance means. As the Enforcement Decree of the Housing Act was revised on April 25, 2014, vertical expansion was allowed and the range of increase in the number of households was expanded. Accordingly, remodeling has changed beyond simple maintenance and repair to a means to respond to reconstruction. These institutional changes brought about changes across cities, complexes, and residential spaces, such as complex planning, residential space composition, residential density, external space and parking planning. Nevertheless, studies that empirically analyze the characteristics of the remodeling project with an increase in the number of households promoted after the institutional change are still insufficient. Therefore, the purpose of this study is to empirically analyze the planning characteristics and trends of the remodeling project. After the system change, the change that appears in the dimension of cities, complexes, and residential spaces was analyzed by analyzing the remodeling complex with an increase in the number of households that has been approved for business plan.
The analysis results according to each aspect are as follows. First, from an urban perspective, the analysis was focused on the landscape, infrastructure, connection processing, and sunlight. As a result of the analysis, it was found that the overall external impact of the number of households increased remodeling was limited. After the system change, the urban landscape may change depending on the size and method of expansion and location conditions. In particular, in the case of the extension of the annex, the skyline change was relatively clear, but the landscape change was relatively insignificant in the vertically expanded remodeling. On the other hand, it was confirmed that it was necessary to secure the specificity and consistency of the operating standards for each local government in terms of processing the infrastructure and the connection part.
Second, in terms of the complex, the analysis was focused on changes in density and number of households, external space, and parking environment. Complexes in the district unit planning area were managed relatively stably through the planning guidelines, but complexes outside the area showed an imbalance between regions due to the density planning centered on the deliberation. Also, there was a difference in the size of the complex. Large-scale complexes were easy to remodel, but small-scale complexes had limitations in securing business feasibility, and the need for institutional and financial support was confirmed. It was confirmed that the utilization of the external space improved through the underground relocation of the ground parking lot, and the number of parking spaces per household also increased, thereby improving. Third, in terms of residential space, it was confirmed that the area of the dedicated space and the flexibility of the flat composition were increased. In addition, it was analyzed that the overall quality of housing was improved by improving the vertical line of the common space and expanding welfare facilities.
This study is meaningful in that it empirically analyzed the characteristics of the increasing number of households remodeling based on the actual business plan approval case and is expected to be used as basic data for planning standards and policy establishment for apartment remodeling in the future. Through the above conclusions, we would like to present the direction in which the increasing number of households should be developed in the future. First, at the urban level, elaborate guidelines for the influence of the landscape and the connection plan according to the scale of expansion and location conditions should be prepared. Second, at the complex level, it is necessary to secure equity in density management depending on whether or not the district unit plan is applied. In addition, there is a need to come up with institutional and financial support measures for small complexes. Third, at the residential space level, it is necessary to pay attention to the harmony between the spatial plan that actively reflects the needs of residents and the quality level of public spaces. Through this, the purpose of remodeling should be expanded to improve the living environment, not to simply expand the area.
