Analyzing Redevelopment Trends and Key Planning Elements in Seoul’s District Unit Plans by Detailed Types

초록

This study analyzed the key elements that changed during the redevelopment process for 131 district unit planning zones in Seoul, selected from the 467 total plans established by the end of 2022, in order to identify specific characteristics and trends by type. The district unit plans were classified into three main categories, and the analysis focused on how redevelopment occurred differently in each category. Among the three types, the "Planning Management" type experienced the most frequent redevelopments, with an average cycle of 110.9 months between redevelopments. The "Planning Management" and "Development and Improvement" types commonly showed significant changes in land use, building density, and floor area ratios. On the other hand, the "Conservation and Regeneration" type had more noticeable modifications in terms of building form, architectural style, and appearance. These findings suggest the need for a more tailored approach to redevelopment processes and underscore the importance of continuous monitoring of frequently altered elements in district unit plans, ensuring long-term effectiveness and adaptability to urban changes. © 2024 Architectural Institute of Korea.
