地下鐵 連結通路와 都心 오피스 빌딩 進入部의 轉移空間에 관한 硏究

Abstract

Many office buildings around us with the development of architectural technologies have greatly contributed to urban developments; however, in terms of urban space in which people walk in downtown, they have acted as the spatial rupture of cities and a factor that obstructs the publicity of the cities rather than something human-centered. To make up for this weakness, public announcement system became obligated and with the increase of the need of interior public announcement system, publicity is now brought into relief. Recently, enterprises, unlike in the past, do activities in each field to contribute to the development of corporate culture and return to society, and it is thought that a leading effort for public good at enterprise level is necessary also in urban spaces. Currently downtown office buildings connected to subway stations are prominent in Gangnam area where there are a lot of business spaces, which has played a role of way transporting people. Underground spaces in Korea with respect to the distribution of subway lines are distributed centering around station influence areas, connections among underground spaces, subway stations and the surrounding buildings occur, most of which play only functional roles. However, in contrast, in commercial spaces accompanied by commercial purposes, a diversity is provided by the connections and the roles of the spaces. As studied in domestic and foreign instances, as time goes by, society becomes complex and diverse and tries to be linked to various spaces, where transportation serves as an essential element. Among them, connections to subways are very important in urban transportations, through which most people try to enter into another space. And office buildings in downtown area, may be regarded as a necessary condition, and as seen in existing cases, public spaces in the lower part accompany with public roles with commercial purpose, which will be open to the citizens as open spaces. In addition, currently commercial functions and public functions in company buildings have occupied large areas; however, in the future, they will have diversity as more complex facilities. According to this flow, the integrated image and public roles of buildings to the citizens using them will be the base that can bring change of men-centered thoughts in urban spaces.

This study understands current problems through study on transition spaces that play a node role as well as a passage and goes through the following course for the types of basic preference needed for the installation of connecting path, a plan for improvement and the improvement of publicity. For Gangnam area with a character of strong business district, as a result of a survey on every target area with a connecting path between a subway station and adjacent buildings based on the data of Seoul Metropolitan Subway Corporation and Seoul Metropolitan Rapid Transit Corporation, 8 locations were selected. It investigates standards for installation and negotiation procedure needed for connection between subway and adjacent buildings related to installation of connecting path, examines general matters for examines the factors affecting the connection, and carries out on-site survey. Based on this, it found out the current status drawing up a checklist of architectural elements for the promotion of the publicity of architecture, including walking space-related element, resting space-related element, green space-related element, and can analyze transition utilizing the elements of the creation of transition space. In addition, the conclusion through questionnaires and case studies for the enhancement of publicity is as follows: First, a symbolic element that can play a pivotal role in space is necessary. As a trend most cases showed, the appearance of buildings personify another object, as if attempting to become the third space. As known from preference analysis of signs through questionnaires, the preference was high for image signs in cases where there were relatively visual openness and resting spaces. It is because a person who perceives space when surrounding conditions stabilize the person's mental state and relieve his or her fatigue, may have leisure to look around the space rather than other directions and accordingly, thinks of an image that gives visual comfort. Second, the construction of association that can get supported interior and exterior space, as a middle area, and induce natural approach. Since space has different image recognized depending on the person who perceives it, it can be described with relative concept. So, the concept of space defined is limited and confined to support actions; however, flexible space includes diversity and supports different actions. Here, association plays a role that binds different experiences and scenes that may be separated. Third, the formation of space with various rhythms and meters is necessary. In Mid Town, a foreign case, the spatial properties are well expressed. In the connection process of entering from subway to building, material expression shows a remarkable characteristic, which finishes the surface of the space but may support the behaviors by color and pattern. Fourth, the concept of promenade should be introduced to become an object that can be experienced and enjoyed. The concept of promenade is a spatial concept which was newly tried in the relativist spatial theory, when a space was attempted to be defined as an object of experiential appreciation. Existing passage was flat space however by processing the form and configuration of adjacent space in various ways to allow people to experience various spaces passing through the space, an experience of a new space can be induced. Fifth, acquisition of visual emphasis is necessary. In a space, the adjustment of strength/weakness between components not only revitalizes the space which has been tiresome and standstill but also supports a new behavior at the same time giving visual pleasure. Sixth, the process of entering into interior space through external space should be harmonized by the introduction of the concept of indoor square. The concept of indoor square was introduced as a means to protect old external space in cities under the late industrial capitalism in Europe. In indoor square, there may be street cafe or street trees may be planted, which feels like outdoor space. Square in underground space can provide a fresh environment linking the feel of indoors which may be dark and heavy among paths and many people to outside. This study examined the physical properties a space should have for its transitional role and discussed plans to support behaviors through spatial approach for the enhancement of publicity and psychological effect. Currently, in fact, the role of the connection between office buildings in downtown and subway stations as transitional space is very insufficient; however, development in the future will be progressed in many sides. Following the flow, continuous studies on this space are necessary and various researches for the enhancement of publicity should be carried out.
