공동주택 공용시설의 최적규모에 관한 연구

Abstract

The purpose of this study was to estimate optimal space for maximizing net values in the interest of tenants residing in such sports facilities and community facilities(except sport facilities) as extensively supply apartment housing complexes in these days. There have not been any domestic preceding studies on optimal space of these facilities that is required a considerable amount of initial investment cost and continuous running cost.

In order to achieve the above purpose, this study adopted Rosen's hedonic price model and multiple regression analysis model for data estimation and analysis. Thus, this study used onsite 665 sample data obtained from 133 apartment complexes(including residential-commercial apartment and common apartment) in Seoul and Seongnam city (Bundang-gu). The research subjects were divided, respectively into the sports facilities within the apartment housing complex, and the community facilities, which excluded the sports facilities.

This article is based on a combination of the following 3 essay topics: The first topic sought to estimate possible space of sports and community facilities within apartment housing complexes in the interest of maximizing their implicit price. The second topic aimed to estimate and analyze possible space of sport and community facilities within apartment housing complexes in the interest of minimizing their operating cost. The third topic sought to estimate and analyze the optimal space of sports and community facilities within apartment housing complexes in the interest of maximizing net value of tenants residing in such complex.

The results of analysis can be outlined as follows: It was found that housing price reached its peak when the space of sports facility was allocated about 2.05㎡ per household, and that of community facility was allocated about 3.25㎡ per household. This study classified high-technology security facilities into 6 levels and sought to analyze possible effects of each grade of those facilities upon housing price. And it was found that housing price could increase as high-technology security facilities became upgraded into certain level, but the excess of such a certain level could not have effects on housing price.

As a result of analysis, it was found that minimum operating cost in apartment housing complex, the space of sports facility was allocated about 2.66㎡ per household and the space of community facility was allocated about 3.08㎡ per household. In addition, it was found that the maximum net values of tenants residing in apartment housing complex, the space of sports facility was allocated about 2.58㎡ per household and the space of community facility was allocated about 3.08㎡ per household.

This study has great implications in the sense that the comparison between practical site data and analysis-based estimation data shows that the facility scale approximate more to estimation data which associated with higher preference of tenants and more activated use of relevant facilities. Moreover, this study also has great practical implications in the sense that its findings will be widely useful for analyzing business feasibility of actual apartment housing complexes.
