This study of almost 600 students examines the relationship between sense of community and college dormitory architecture on the campus of a small residential liberal arts college in the Northeast. Respondents of all class years completed an online survey that included the Sense of Community Index and the Relationship dimension of the University Residence Environment Scale. Students also rated architectural characteristics about their dorms and provided background information. Results indicate significant differences in sense of community related to dormitory design, in particular a lower sense of community in dorms that are organized around clusters or suites. At the same time, these units in clusters are judged to be more positive in terms of basic architectural components, including thermal comfort, adequacy of bathrooms, and storage. Results are discussed in terms of recommendations to enhance a sense of community through design. (Contains 6 tables and 2 figures.)
