Abstract

In Korea, more than 50% of buildings are over 20 years old. In addition, in the case of houses, 45% of buildings that are more than 30 years old are rapidly deteriorating. Large-scale complete removal methods, which has been actively conducted since the 1970s, has been carried out without considering the regional characteristics or the historicity of the city. As a result, a repair-type maintenance method was introduced to induce small-scale development. However, there are lots that are difficult to develop under the conditions of the lot. These lots need cooperation with adjacent lots. Methods for development in cooperation with adjacent lots include maintenance through parcel-union or building agreements. The study of small maintenance was conducted on more than 90m2 of land. Under parcel less than 90m2, it occupies more than 15% of the core, so research on core-sharing is necessary. Therefore, the purpose of this study is to find out the characteristics that appear when small-scale maintenance is performed according to the number of lots that share cores in a dense area of undersized parcels, such as increasing the dedicated area and flat type and increasing the number of households, parking space, and utilizing external space. As a result of the study, if cooperative development is carried out through core-sharing, the exclusive area of 73.2~325m2 can be used, and the type of residence varies according to the layout of the lot. In addition, it was found that the securing of parking spaces and the utilization of external spaces were also increased. Although cooperative development is still not actively carried out, this research is valuable in that it can bring great effects when cooperative development is carried out in at least two parcels.
