Posing problems on Seoullo 7017 public parks, the study attempts to criticize not only that the ‘hanging garden’ is just a fragmentary urban artifact without any means of sup- plementation to mark the beginning and the end, but also that there is no story-telling that can complete the context with the elevated bridge. Putting the case that the Seoullo is a geographical branch outgrowth from the Nam-San, we attempt to extend a glass wall supposed to be a fragment of urban elevation to the Namdaemun, to make the glass box meet the terminal point of the bridge, and to have the Seoullo 7017 have reason for being. A horticultural garden is proposed as a program, which also celebrates the disappeared Nam San Botanical garden and which motivates the pedestrians to move up to the Nam San. Keywords: Seoullo7017, horticulture garden, Nam-san mountain, regeneration. 1. Introduction 1.1 Background and Purpose of project Seoullo 7017 is a urban renewal project to recycle the elevated highway over- passing the Seoul Railway Station used for logistics that links the Seogye-dong area of Yongsan-gu with the Namdaemun market, into a so-called "urban corridor". A paradigm shift from trading to a place of wandering, has made the overpass itself degraded into a no man’s land drifting in the air. The study departs from a criticism on pointless architec- tural deeds under the pretence of urban renewal. In other words, it raises a question about not only an absence of devices that complement a beginning or an end of such a piecemeal policy to create of a public park in the air, but also an absence of story-telling that com- pletes the context. The study attempts to add a supplementary object as a topographic branch out of Mt. Namsan, that gathers and extends the fragments of city elevations to be landed on the end of the overpass-park, and to help the reason for the existence of ‘Seoullo 7017’ to be verified. Programmed by a horticultural garden that commemorates the past Namsan Bo- tanical Garden deleted, the study intends to extend the object’s volume vertically and to provide the artificial air park made of cement with a moment to meet the real nature of the mountain. 1.2 Contents and method of project Even though Seoul Station-overpass is recycled to be a park in the air as a response to the paradigm shift according to urbanization and as a solution to the environmental issues, however, such urban renewal results in nothing other than another piece of urban artifacts in perspective of urban ecology. What this Project really aims at is, therefore, elevating the value and propriety of the overpass park, by linking with the Mt. Namsan, which is presently deserted in the air and alienated from the city context. © Kim Na-yeon, Koo Young-Min, 2018 107 Том 2.

Reasons and analysis for site selection 2.1 Site selection and Reasons The target area is located between the boundary where the city meets the Mt. Namsan, and the landing spot of the ‘floating park’ over-passing the Seoul railway Sta- tion. As mentioned earlier, the main problem of the ‘Seoullo 7017’ renewal project is originated from the fact that the Seoul–Station- overpass has lost not only its function as transportation system in logistics, but also its contextual link with history and society, and eventually that the simple floating object places its reason for being in jeopardy. Assum- ing that this artifact is to be extended by any means to be a mediator that helps the city and nature coordinated, however, not only a new value in the sense of place is to be cre- ated, but also a balanced urban ecology is to be achieved. Figure 1 Seoulstation - overpass transportation and location 2.2 Site analysis Amalgamated with urban history and nature, tourism and city infra facilities including the Namdaemun Market and the Seoul railway Station, Namdaemun and the mountain. Namsan, the area around the site is a major traffic point in Seoul but at the same time, a disorderly context in urban ecology. Remained void not reached by pedestrians, the foot of the mountain. Namsan collided with the city has been left to be no man’s land from either nature or the city.

Design process 3.1 Deriving concept Urbanization has gradually expanded traffic roads and clearly defined the boundary between nature and the city, divided the city into fragments to disconnect the flow of space and made nature an object in the city. Narumi Kunihiro pointed out that the modern city’s problems is originated from a fragmentary development of a mega city. Seoul also has built, in an absence of link between the city and nature and of ecological integration between the two territories, ambiguous border conditions. Piecemeal deeds on restoration and renewal in the city results in a fragmentation of overall urban space including, for example, the site located between restored but neglected walls and high rise buildings, a void disclosing the gap between the past and the presence in time, and a desolate path in the ‘Seoullo 7017’ with no concern with city flows. Therefore, the concept of design departs from signifying vertically fragmented city elevations and sections into the ecological flow of movement linking nature and the city and various programs.

This project is reno- vation administration building of the insurance company. He tried to make space volume for use by public. This inserted space volume must be delineated external space within constructed building and be made available to the public for further development. Stand- ardized and regulated office space can be contain various forms of public space. Figure 11 Wolfgang Tschapeller BVA1 models 3.3.1 Morphosis, Cooper Union Building This is a cooper union for the advancement of science and art by morphosis in Newyork, USA. A vertical central space for informal public forms the heart of the aca- demic building. He intended the grand-opening space lead to social, intellectual and cre- ative exchange. Further reinforcement of the strategy to create vibrant intellectual space is provided by short, crossed circulation for more impromptu meeting opportunities.

Новые идеи нового века – 2018 Vol. 2 New Ideas of New Century – 2018 5.Conclusion Under the pretence of urban renewal in critical perspective, the study attempted to proceed the design experiment from the point of view to complement the dissatisfied result of the urban renewal project of 「Seoullo 7017」. As a result, the study recognized that urban renewal or regeneration intervenes in the existing context to generate a new storytelling through which the urban context is transformed to inherit the essence of history. The study was able to support the reason for being of the ‘Seoullo 7017’ by complementing the Mt. Namsan and Namsan castle that has been alienated from the context, and the promenade linking to the Namdaemun, and to verify such a design approach to be not only another attempt to grasp urban ecology but also a strategy to overcome the limitations of fragmentary urban renewal. What signified this research is, therefore, that the link among new society soon com- ing, nature, and urban psycho-culture is groped for in depth. Bibliography 1.
