This paper follows two interrelated studies. Through the first study, we explore, classify and evaluate predictors that contribute to an increased place attachment. Through the second study, we examine the predictors on a residential complex in Tehran. Surveys and face-to-face interviews were conducted to investigate place attachment and the relationship of attachment with the overall design of their environment. The findings indicate a significant attachment to the neighborhood, which contributes to the users' tendency to remain in the community. Also, physical dimensions of attachment are regarded as crucial in developing a sense of belonging. (C) 2011 Published by Elsevier Ltd.
