In the urban area where rapid suburbanization trend continues, the role of mixed use building is controversial. It is
argued that the mixed use building is an effective tool to recover residential function of urban core(urban regeneration).
It is also argued that the building is a cause of serious urban problems, such as congestion, public service shortages.
The fundamental purpose of this study is to examine the role of mixed use building in terms of urban growth
management in Seoul. For this purpose, data of mixed use building from 1981 to 2007 are collected and analysed. The
results show that most of mixed use buildings are located in either sub-centers or population losing areas, rather than
traditional urban core. Therefore, it is hard to accept that the two controversial arguments. The mixed use building noncore
areas in most cases. However, it dose help to increase population inflow in non-core areas. it is difficult to accept
the public service assertion which states that super-high rise mixed use building causes public service congestion, because
the building is built in population losing or demand decreasing area. Based on these findings this study suggests some
policy alternatives such as urban service boundary or concurrency program to management urban growth.
