Although the large supply of multi-family housings played a very important role in forming the urban structure and allocation of functions, and also enhanced the whole level of housing environment, it caused several problems relating to physical form such as isolation of housing estate, inhumanity of the exterior space, and mismatch with the urban structure. To handle these problems, the purpose of this study is to analyse design elements which have a direct impact on physical forms, thereby understand the characteristics of planning. Therefore design elements are reformed into respective analyzing indices. This study analyzes design elements based on analysing indices. Thus, several important results were found from the Factor Analysis and after classifying housing estates into several types, the study found the characteristics of planning within each type of housing estates.
