The current residential environments have not been designed for the activities and needs of elderlies, so addressing the quality of interaction between older adults and the surrounding physical environment is necessary. On the other hand, the ratio of the elderly population percent to the total population is increasing in the upcoming decades, and the world in general, and Iran, in particular experience aging. Therefore, this study was conducted to find how aging interaction is shaped in the place to achieve a theoretical and practical perception of aging interaction in the place. To do this, a qualitative research strategy was selected and the interview protocol was pursued based on the five topics. Older adults from the Iranian community living in Canada were selected as studied samples, and assigned to two groups, including 43 interviewees in urban place situations and 50 interviewees living in suburbs. After the in-depth interviews were done, the responses were saturated, and sufficient statistical society was obtained. The data obtained from open interviews share some subjects about older adults' feelings about the place and the reflection process for making decisions about aging in the place or relocation. Five thematic coding categories were pursued through qualitative data: the importance of the house, house comfort, properties of the neighborhood and community, difficulty in home affairs handling, and safety and security concerns. The study results indicate that elderlies pay more attention to the functional aspect of the house and immediately point to those environmental properties with unsupportive natures. Ultimately, the research findings indicate that the concept of a house supporting aging interaction in place has been defined based on the residence place of older adults through six components: designing several realms for the house, creating permeable borders and transparent margins, environment safety, improving kitchen access, restrooms, and bathrooms supporting aging in place, and access to nature.
