The emphasis of this research lies in its focus on the arrangement method of the apartment blocks, which is deemed instrumental in determining the external physical environment of living in apartment complexes. The objective then, is to examine the transformation feature of the block arrangement of apartment complexes according to each period. Applying space syntax as a methodology allows the research to define the scope and underlying principles of reenacting the spatial structure of the external spaces in a complex. The following step is to establish a criterion for examining the transformations in block arrangements. Among a variety of criteria available in classification such as the number of levels, core form, block type, and the specified unit area types, this research seeks to examine the block arrangement with specified unit area types as the central focus. Based on social phenomenon and its characteristics, the final step involves classifying the periods into six different time frames, and through the resulting analysis of each complex the study ultimately determines the periodical trend in block arrangement. The outcome of this research is an in-depth analysis of the periodical transformation in the arrangement of the large unit area types and small unit area types within the apartment complexes and its underlying meaning.
