This study was conducted to investigate the indiscriminate development occuring as a result of high-density land use per lot in residential areas of Seoul, which mainly consist of detached houses. The primary goals of this study were: (1) to suggest a block unit development method as an alternative architectural method of the current uniform development, in which high-rise and high-density apartments are usually built; and (2) to check the feasibility of the suggested method. Based on the analyses of the existing block composition types of residential areas, the prerequisite planning indices for applying a collective housing model were investigated. Subsequent to applying a collective housing type within each unit block, the collective housing model was analyzed. The results of the analyses showed that indiscriminate development was rampant in detached urban houses areas, and more than 70% of the buildings constructed before the 1980s needed re-development. The feasibility of the models was investigated depending on the models of low-rise and high-density collective housing, which utilize various block arrangements such as the court type, linear type, villa type, and composite type. The results of this study showed that the newly applied low-rise and highdensity multiple dwelling housing model in urban individual residential area significantly contributed to creating a good living environment in terms of both physical and psychological aspects.

The Purpose of this study is to find out necessity and possibility of low-rise high density housing improving an old residential district of hillside areas. Housing of hillside areas should be maintained and it is necessary to make topographical adaptation plan. For this purpose, we calculate the floor area ratio to break even on case study area by GIS date. As a result, we found out that floor area ratio as minimum qualifications for the feasibility of urban redevelopment is 180%, and carried out a landscape simulation to a low-rise high density housing by AutoCAD 2004 and ArcView 3.2a. In results of simulations, it reveals that a rule to low-rise high density housing effective for topographical adaptation development.
