Organization of living environment is possible through a clear definition of private and public arenas and determination of a spatial hierarchy. Such defined arenas increase the sense of belonging to the environment which personalizes residential environments. Enclosure is among the quantities that play a significant role in defining the spaces. In fact, enclosure is the factor that defines a space as a ground for occurrence of other events. Enclosure is an individual subjective ground to define the space and the primary factor in conversion of space into place. One of the basic functions of a house is to determine a territory. This paper considers the concept of territory as an effective factor on the quality of the relationship between the human and his residential environment and investigates the effect of enclosure on this territory. Two residential areas including a part of Haft-Hoz neighborhood and Shahrak-e Gharb (West Town) were selected as the sample of the test. The effects of enclosure factor on the concept of territory were analyzed in common residential complexes. A qualitative research method was applied and questionnaire was used as the scientific method. According to the belief that the relationship between human and the environment depends on many different factors, this paper investigates and analyzes the concept of territory and spatial enclosure as one of the effective factors on the quality of the relationship between human and residential environment in the mentioned neighborhoods.
