세운상가군과 주변구역의 도시·건축계획의 변화에 관한 연구

세운상가군과 주변의 도시·건축계획 및 재정비계획 변화를 분석했다.

The purpose of this study is to analyze the characteristics of the international competition of urban architecture and the urban management plan (rehabilitation promotion plan) which have been constructed since the end of the 1960 's and have been completed in the early 1980' s, We discuss the changing factors of urban construction policy in the period. The Sewoonsangga built in 1966 built and completed in 1981 puts the history of the City Center. When it first appeared, it formed a major commercial district in Seoul, but as the city's development in Seoul was expanded rapidly, it quickly became outdated.

Since the 1980s, Sewoonsangga has been criticized for its enormous size, cutting off the direction of Seoul's eco-consciousness, incompletion of a three-dimensional walking deck, and erroneous building of public land. In the end, the city announced plans to demolish the sewoonsangga built in 1995 and to create parks. The Seoul Metropolitan Government was planning to meet the cost of demolition and creating the park by developing and integrating the surrounding area. Through the international competition design of urban and architectural integration carried out in 2004, redevelopment projects for the Sewoonsangga and surrounding areas began in earnest.

By integrating urban planning and architectural designing, we were able to speed up the redevelopment project. 2009 was the year of finishing the first phase of the redevelopment project and pushing ahead the second phase of the project. The first phase of the project completed compensation for landowners and merchants to Hyundaisangga. The Seoul Metropolitan Government(SMG) set up a temporary sales facility and made the merchants included in Phase I to the temporary sales facility and demolished Hyundaisangga in December 2008. In 2009, the Sewoon urban regeneration strategy plan was established for the entire area, and Sewoon 4th district completed the project approval process.

The deliberation on the cultural properties of the Jongmyo started in July 2009 dismissed the projects that had been promoted rapidly under SPECIAL ACT ON PROMOTION OF AND SUPPORT FOR URBAN REGENERATION. The plan with a floor area ratio of less than 850% and a maximum height of 122.3m was to lower the height of the building, as it cuts through the exterior view from the Jongmyo. As it is a necessity to pass the deliberation of the cultural property to promote the project, the height was decreased from 122.3m to 75m. Decreasing the height of the buildings reduced the floor area ratio to 632%, and finally the business was not able to be secured.

The integrated plan of city and architecture that has been established since 2004 has become a proposal that can not be realized. In the end, the city of Seoul faced an embarrassing situation in which it had to change the proposal to a size that passed the deliberation of the cultural property. In 2012, SMG started establishing historic city center basis plan, and decided to cancel the Sewoonsangga demolish project, reorganized ACT ON THE MAINTENANCE AND IMPROVEMENT OF URBAN AREAS AND DWELLING CONDITIONS FOR RESIDENTS, SPECIAL ACT ON PROMOTION OF AND SUPPORT FOR URBAN REGENERATION entirely. In 2014, the plan to promote the resettlement of Sewoon's urban management plan has been changed.

Since it does not dismantle Sewoongangga, it has reduced the burden of securing excessive infrastructure. It has changed from integrated maintenance to small and medium scale to maintain existing urban structure. The height of the building was reinforced by height regulation of the horizontal zones. It also strengthened the use of existing industries. After the urban management plan was established, the architectural competition was held three times from 2015 to 2017. The scope of the competition was in the field of architecture.

In the urban management plan, the master plan of the architect was not necessary because it reflects the residents' opinions, accepts the upper urban management plan, and links the existing horizontal organization. The integrated design of urban and architecture existed since 2004 has been separated since 2014. Since then, the role of the architect has been reduced from the whole to the part, from building the master plan to following the urban management plan. When Sewoonsangga was first constructed, it tried to solve the shortage of housing by building private buildings on public land.

the sewoonsangga, which was built to the maximum floor area ratio, did not realize a three - dimensional walking deck and lacked publicity because it proceeded too much to promote the business. In the 2000s, the public sought to recover public facilities by public space, but it was very difficult to compensate for buildings with the maximum floor area ratio. Since 2014, the role of the public has been reduced, and old buildings such as the existing residents, the existing urban street organization, the residence of Sewoonsangga. The role of architects has been changed to design space to recover and revitalize existing urban organizations.

As the floor area ratio is reduced due to the height regulation of the architectural design, the floor coverage ratio has been relaxed to less than 80%. When the coverage ratio was 60% or less, the space like the road in apartment, the open space, the walkway were sufficient, but the outside space of the city was reduced as the coverage ratio increased by 80%. Changes in the use and scale of the buildings changed the design of the buildings from the design of the high-rise buildings, which adjusted the skyline of the high-rise buildings, to the design of the lower buildings.

Regulation of the height of the buildings due to deliberation of the cultural assets can not guarantee the business feasibility of the redevelopment project of the restoration of the historic status of the city center. The type of redevelopment project has changed by analyzing the redevelopment projects of Sewoonsangga and surrou
