After the introduction of urban design, the creation of urban design provision in Building Code 8-2, January 1980, have changed the circumstance of urban design during about 20 years.
In urban design, "the Special Zoning District(SZD)", the narrow scope of urban design, was involved in our programme so it has been operated without exact definitions and proper processes and there is another similar programme which was defined in Building Code in 1992. But there are numerous views and directions about applications of it, so the concept of SZD is not settled.
Under the circumstance, the purpose of this study is to analyze the past numerous aspects of urban design and the meanings of the past SZD programme in order to established the exact definition and proper applications, and to analyze the result and problem of SZD as comparing urban design status following regulation substance by urban design guidelines and it's applications.
This study is consists of following five parts. The first part reviews the concept and general characteristics of SZD and theoretical background on the urban design guidelines, urban design regulations and control elements.
In the second part, author inspects that what role did play and what contents did contain the zoning and the urban design, by means of case studies which have American and Japanese urban planning system and related urban design institution.
In the third, the case study of 10 cases (Seoul-Jamsil, Seoul-Teheranro, KOEX, near Kangnam Station, Seoul-Daehakro, Yulgokro, Sungnam-Bundang, Koyang-Ilsan, Pusan-Haeundae, Anyang-Pyungchon, etc.), has been analyzed in terms of guidelines contents factors and urban design process. And the last part of this study evaluations the result of the comparisons and then suggests the future study.
The result of this study are as follows;
1) Special Zoning District in urban design regulation: The purpose of SZD can be as follows even though the methods are difference. ① Reserve the land which is difficult to predict the development phase, ② To build public land in historical and cultural site, ③ To attract specific land use in terms of urban design, ④ Reconsider the urban design later if the site has a great impact to the neighborhood.
2) Urban design process of Special Zoning District: SZD has a difference method compared with general urban design methods which rigid guidelines. It can have a flexibility considering the characteristics of land and the aim of development which can't deal with in the process. This flexibility can be beneficial since land owners and the size of are small.
3) Urban design guidelines in Special Zoning District: SZD has two parts of guidelines. Urban design guidelines after the programme district is pointed, detailed guideline after it was defined. When the district was settled, it must have directions of development and purpose of urban design in order to know the contexts of urban design to the future developer and the guidelines should have constant control to keep the continuity.
