Abstract
The effects of architectural settings, especially the dwelling-unit plan, the access type of the collecting together of units and the scale of grouping, on the process of territorialization were investigated. The dwelling-unit plans were classified into three types, that is, "Single-orientation unit; its back to the access", "Single-orientation unit; its front to the access" and "Double-orientation unit". The access types were "Single-loaded access" and "Double-loaded access". 13 collective housings, mostly low-rise, yielded 626 questionnaires of wives. The result supports the following statements. (1) The effects on the process of territorialization is extremely different among these types of unit plan and access system. The types that most help inhabitants to territorialize their neighborhood are "Double-orientation unit" and "Duoble-loaded access". (2) The scale of grouping that encourage the territorialization is limited to 15〜20 units.
