The residential area in Seoul had some problems created before the 1980s. Naturally-occupied residential area is with insufficient infrastructure and bad housing, and even in the case of the superblock was also created at the expense of green space and various infrastructure for the quantitative supply of housing. In this regard, we proposed regeneration plans for the superblock, which occupies as a representative residential area occupying 64% of Seoul. The regeneration model of the small residential superblock is to secure the walkway while securing parks, parking lots and community facilities. Practical implementation plans should be linked to district unit planning by designating the area of street housing maintenance projects and introducing “Type of Residential Area Management District Unit Plan” including “Park Common Block” and “Green Belt”. The Regeneration model of the apartment complex Superblock is to communicate and connect with the surrounding small residential area and to form a semi-open complex. Considering the size of the surroundings, the block is divided based on the basic module of 100x150m, and roads, parks, and cultural facilities that should be basically provided within the 30% of the total area of the site. Social consensus and improvement of capacity ratio system are needed, and the introduction of the “Block-by-Block complex-use Plan” system to mix usages by block should be discussed together.
