Problem statement: In many cases, the lack of space causes the people’ s loss of the comfort and sense of territory. It further leads to unwanted spatial communication with each other. Physically, on the boundary of the space, if it is not an obstacle to communication, it causes olfactory communication, visual, audio, access, and violation of all types of privacy and ultimately violates the privacy of users. Research objectives: The present article aims at improving the theoretical foundations of the concept of privacy by determining the factors affecting the provision of privacy in contemporary housing space from the point of view of environmental psychology. Environmental psychology studies human behavior in order to perceive the relationship between privacy and social life. Research method: This research is a descriptive-analytic type with a research method of logical reasoning. Conclusion: The architectural representation of the spatial arenas, spatial boundaries, in-between space, hierarchy, spatial depth in responding to human needs: safety, respect, introversion, and the realm of contemporary housing are summarized. The main result of the research on 6 types of different types of units from the residential tower of Milad Tabriz indicates that the control of spatial communication in the architectural design leads to the control of behavioral communication in human interactions, which is one of the most important factors in providing types of privacy, including visual freedom, access, . . . and ultimately mental privacy in contemporary housing.
