By surveying the residents of Tainan, this study examines how elements in physical design affect the sense of community and neighborhood relationships. There are three concepts derived from the ―sense of community‖: ―social connection‖, ―attachment to the neighborhood‖, and ―local acknowledgement‖. Psychological cognition and behaviors are positively associated; thus the sense of community and neighborhood relationships are closely interrelated. The two housing patterns of town houses, whether pedestrians and vehicles share the same routes, have no significant effects on neighborhood relationships or on the sense of community. This study reveals that residents are generally proud of their neighborhood/community, but interaction with new neighbors and participation in social activities remain passive. In general, longer tenure leads to a higher local acknowledgement and better neighborhood relationships. The results of this study also reveal that stable residents in the community and long-term habituation lead to fewer neighborhood contacts and lower local acknowledgement among those whose tenure are more than 15 years.
