In this paper, the effects of neighborhood planning on inhabitants are viewed in the light of the daily behavior and feelings of inhabitants, neighborhood cohesion and the social relationships with their neighbors, using survey data in multiple dwelling house estates. In its analysis, the relationships between the perception of territory on the one hand, and the housing type, the number of grouped dwelling units, the way of approach to individual dwelling unit, the human contact with neighbors, the united activities among neighbors and the like on the other are examined. As a result, the neighborhood was classifyed into two or three divisions in terms of the perception of territory, in the case of surveyed housing estates. In addition, It was realized that the physical and social thresholds and nuclear spaces in neighborhood played an important part, whenever inhabitants perceived a certain territory. In other words, the possible interaction effects among the perception of territory, threshold and nuclear space in neighborhood were suggested.
