As the modern-day Apartment Complex has varied community facilities such as health care center and self-improvement institutions affecting the residents' quality of life, this paper is for the in-depth understanding on how such Exterior Space vary and development plan should go. To be specific, this paper is to, based upon the theoretical contemplation on the concept and role of the Exterior Space to Apartment Complex, as well as drawing a conclusion on the development plan for subject areas as assessed. Subject areas of this paper are a total of twelve Apartment Complexes built since Year 2005 in nine different regions in Seoul. As such specialties and features as leisure of the senior citizen and female residents, the subject Apartment Complexes have provided opportunities, active and inactive, to the residents for leisure by qualitative improvement of facilities, as well as establishing the discrete brand value for the Exterior Space with featured design and spatial properties. Also notable is the eco-friendliness of the Exterior Space with cutting-edge technology, eventually appreciating the value of Apartment Complex.

Purpose: Recently, Housing area plan has tried to reflect a public space of various forms. However, most of cases are indiscriminately developments, which don't reflect the diverse needs of residents. In addition, a subject of the public space is not clear and consistently stable of the management, so the residents don't have an interest enough to take advantage of it. Method: In order to make a plan of the public space of a residential complex, an architect designer needs to take a few things into consideration. One is a physical facility in needs. And other one is a management of keeping a social place stably and consistently, which allows residents to be able to interact with each other. It should be regarded for residents to form a sense of belonging, while minimizing the interface friction. When all these problems are fulfilled, an interaction will be made to improve the quality of the living environment. Result: Therefore, in this study, it is necessary to define the meaning of territoriality of the external public space of housing complex. This study makes it possible to improve the relationship of neighborhood and the quality of the life for the residents, depending on the time. This is the first step as 'the research for the territoriality of the external public space of housing complex', in order to define about the concept, function, characteristic of territory(the base of territoriality) and to establish the territoriality that can form the physical or psychological boundary in public space.

최근 도서관들은 도서관의 본연의 역할을 충실히 하면서도 지역주민의 변화하는 요구를 충족시키기 위해 역할다양화를 모색하고 있다. 복합문화공간의 조성과 이를 기반으로 한 서비스 제공이 역할확대방안 중 하나이다. 본 연구에서는 현재 복합문화공간을 조성하여 운영하고 있는 도서관의 이용자들을 대상으로 설문조사를 수행함으로써 도서관의 복합문화공간에 대한 인식도, 복합문화공간에서 운영되는 프로그램에 대한 선호도와 인식을 조사 분석하였다. 그 결과, 첫째, 공간 선호도에서 정보공간, 교육공간, 휴게공간을 선호하는 것으로 나타났다. 반면, 커뮤니티공간과 체험공간은 낮은 선호도를 보였다. 둘째, 복합문화공간을 활용한 교육프로그램, 전시프로그램, 공연프로그램을 선호하지만 체험프로그램과 커뮤니티프로그램은 선호도가 낮은 것을 알 수 있다. 따라서 이용자에게 정보 교육의 공간을 제공함과 동시에 전시 및 공연공간을 마련하여 프로그램을 운영할 필요가 있으며, 도서관 복합문화공간은 정보 교육의 공간뿐만 아니라 문화와 힐링, 체험, 소통 등이 이루어지는 공간임을 홍보하고 이용자의 인식을 개선할 필요가 있다고 본다.

The purpose of this study was to establish the more rational and practical basic theory for the landscape planning in the aparment complex. In this study, the actual conditions of exterior space, the residens' satisfaction degree and the correlation between exterior space and the residents' satisfaction defree were investigated and analyzed on the 13apartment complexes in Taegu City. Through the statistical analysis, the main results were obtained as fellows : It was found that the size of green area ratio in the apartment complexes were in the order of Jugong Apt. (Korean Housing Corporation), Siyoung Apt. (City Operation), Minyoung high-rise Apt. (Private Business) and Minyoung low-rise Apt. (Private Business) complex. The highest ratio of footway and Parking area were shown in Minyoung high-rise Apt. complex. The important factors at the exterior space of apartment complex were composed by 6 major factors, importance degrees of which are Visual, Practical, Convenient, Sentimental, Recreational and Spatial factors for teenagers in orders. The residents' satisfaction degrees to the exterior space were highly correlated with the spatil organization, size of green area and quantity of trees, view, management situation, defensibility of outside noise, rest place, water landscapings by turns. In order to get more than the average satisfaction degree 18 exterior space, the green area should be occupied by 35% of the apartment complex area and more than 76% of the green area (i. e. 16% of the apartment complex area) should be planted with trees. In the Taegu City regulation, the ratio of tree composition is proposed for only the number of tree. But it was shown that the satifaction degree are more correlated with the species and afforestation of trees than the nuts her of trees in this study. therefore, the species of tree and the afforestation of tree should be considered when the landscape planning of the apartment complex begins. It was found that the ratio of afforestation to make the more desirable exterior space In the apartment complex shoule be 8 to 2 in the ratio of arbor to shrub. It was also required that 30 species of arbor and 15 species of shrub should be planted for the more desirable landscape of the apartment complex.
