서울시 주택재개발사업에 의한 아파트단지 경계부 환경특성에 관한 연구

서울 주택재개발사업으로 조성된 아파트단지 경계부의 환경특성을 분석했다.

As Housing Renewal Project is conducted in inferior and old detached dwelling areas, which leads to the furtherance of apartment housing complex instead, 'Borderland' has come into existence, located right near to adjacent residential areas. Therefore, this study was carried out with a critical mind that at 'Borderland' will dramatically take place some aspects of the project conducted in a individual zone unit without considering nearby areas.

Accordingly, in consideration of the absence of any preceding researches specifically dealing with the scope of 'Borderland' defined in this study, an empirical case analysis was conducted to investigate possible problems in details, aimed at the Housing Renewal Project District in Seoul. The purpose of this study is to investigate the compositive characteristics of a Borderland taking place when a new apartment complex adjoins the nearby environments and analyze the environmental characteristics caused between the compositive characteristics and the relational characteristics.

In addition, by investigating improved cases complementing the environmental characteristics exposed by the negative effects, the study aims to make suggestions for improvements. In advance of an actual analysis, this study defined the term, 'Borderland', established 'compositive elements' and 'Relational characteristic elements' through an empirical analysis and provided analysis items to analyze the environmental characteristics through the preceding study and on-site investigation.

By analyzing what compositive element composes how many of Borderland and what characteristics compositive elements have, it was possible to investigate and analyze the compositive characteristics of small and medium sized apartment housing complex. The compositive characteristics of a Borderland can be summarized as follows: Firstly, it was investigated that as for the compositive characteristics, the Borderland of an apartment housing complex by Housing Renewal Project in Seoul is generally surrounded by roads for 63.03% while the rest 36.94% adjoins right the nearby plots.

Secondly, it was analyzed that as for the characteristics in size on the basis of the number of households constructed, when the ratio of infrastructure is low, the ratio of non-residential facility use in the small size while the ratio of parks and green spaces in the large size. Thirdly, the changed distribution of the number of households constructed on the time series was possible for the sectional establishment by the methods and policies of Housing Renewal Project, and the changed aspects within a section were affected according to the changes of apartment housing policies.

Besides, it was possible to classify the sizes into small, medium and large on the basis of before-and-after 1997. Finally, it was found that compared to before 1997, in small and large-sized apartment housing complex after 1997, the Borderland has a low ratio of adjoining road facilities with a high ratio of residential area, which can make it possible to interpret as efforts to solve problems caused by the lack of infrastructure and efficient arrangements of buildings, expansion of infrastructure according to the reinforcement of policies for floor area ratio, or efforts to solve civil appeals such as sunshine-related damages.

After completing the analysis on the compositive characteristics, the environmental characteristics of the Borderland were analyzed so that it may be found what compositive element adjacent to the Borderland cause what kinds of environmental characteristics by particular relational characteristics between the apartment complex and the nearby facilities, for which 5 analysis items were provided such as safety, convenience, amenity, activation and privacy.

As a result of the investigation, it was possible to establish the scope of objects affected by the compositive elements of the Borderland in each item, and the probability of positive or negative effects on the objects and its details were analyzed by the relational characteristics. The environmental characteristics of the Borderland can be summarized as follows: Firstly, as for the safety, an analysis was carried out about the safety of streets to school, the safety of streets for walking and the safety of residential areas.

The safety of streets to school required the same-line plan in consideration of the safety of students using the same line with vehicles while the safety of streets for walking might face the risks of pedestrians' falling due to the different level between apartment and road, retaining-wall collapse, crime induction possibility.

As for he safety of residential areas, it was investigated that in case of the nearby residential areas, there are crime prevention-related problems caused by the different level between apartment and residental area and other problems about the deterioration levels of buildings while in case of an apartment complex adjoining green spaces, there are natural disaster-related problems. Secondly, as for the convenience, it was classified by the compositive elements into the convenience of using roads, the convenience of using pedestrians' streets and the convenience of using facilities.

It was investigated that certain problems decline the convenience of using roads, such as using the same main exit and entrance road for vehicles, the different level between adjacent area and road and illegal parking while the opening of transit roads in the complex and similar time zones for vehicle movements have positive effects. As for using streets for walking, there took place some problems caused by the loss or interception of the main streets for walking in the existing residential areas and the private ownership of streets for walking.

As for the problems of the convenience of using facilities, problematic cases were investigated such as the declination of the convenience of using community facilities in the adjacent residential areas
