Around campus, one-room type multi-family houses have been built for more than any other types of one-room type dwelling units. However, these houses are built in a very small scale and have insufficient facilities due to the limited capital invested by the owners of the houses. Consequently, one-room type multi-family housing are lack of consideration and care for various dwellers. This study examines the existing condition of one-room type multi-family housing around campus and analyzes the data collected from the interviews and analyses of the floor plans of the housing. Finally, based on the findings from the analyses this study suggests the future direction for the planning of one-room type multi-family housing.
