In the contemporary world, due to crisis of meaning and loss of individual identity, the importance of paying attention to individual growth and attempt for self-actualization have become more and more apparent. Self-actualization is a biological and psychological necessity and the fundamental tendency of every human being to realize his / her potential capabilities is embedded in its existence from the beginning, so that they aspire to reach the highest level of selfawareness and integration of physical, social, mental, and emotional needs. Housing is one of the most important and essential needs of every human and one of the strongest physical, psychological, emotional, and spiritual concepts in human life. Residential spaces are among the spaces that have the most use for human and humans are constantly interacting with them to the greatest extent. Therefore, due to the duration of presence and continuity of communication with the residential space, this space can be considered as having a great impact on people; thus considering the importance of the effects of the residential environment on people, it is necessary to design housing in such a way so as to clear the way for growth and prosperity of people. Because not paying attention to self-actualization will cause disruption in personal growth and development and in important spaces such as the housing, in addition to being harmful, it will prevent the formation of a meaningful relationship between the individual and space. So due to the mentioned necessity, the present study aims to provide the dimensions of design of residential complexes based on selfactualization of residents according to the perspective of experts, and the mixed research method (quantitativequalitative). The study population in this research is specialists in the field of architecture and urban planning and sampling has been done by snowball sampling method. This research is accepted using the Delphi exploratory survey method and according to the opinions of the members of the Faculty of Architecture and Urban Planning of universities and in two stages: In the first stage, after the feedback interview with the experts, using the open and axial coding technique, the concepts are categorized and include: interactive environment, environmental attractiveness, security and comfort of the environment, nurturing environment, discoverable environment, controllable environment. Then goal-content table is formed and based on this, the researcher made the questionnaire. The survey was conducted in two rounds and the questionnaires were completed by experts in the field of architecture and urban planning. The obtained data were then fed into SPSS-23 software and analyzed using Q factor analysis, Pearson correlation test, and Friedman test, and finally, the most influential dimensions on the self-actualization process were identified from the experts’ perspective. The results of this study indicate that according to the opinions of experts in the dimensions: "Cognitive-semantic, perceptual-experimental, psychological-mental, interactive-social, physical-somatic, functional-activity" in the design of residential complexes can affect the self-actualization of residents and meanwhile it was found that psychological-mental, interactive-social and cognitive-semantic dimensions from the experts’ perspective are the most effective factors on self-actualization of residents of residential complexes.
