抄録

The author built up a hypothesis that the residents have much sense of territory for their common areas and the security is high in high-rise buildings with elevators serving only two families per floor (the author call "two-families" type), because small families share a building entrance. In order to verify this hypothesis, the author set up a questionnaire to the redidents of some different types of high-rise buildings. The results were as follows; (1) In the building of "two-families" type, housewives could distinguish between redidents and strangers in the elevator better than who live in other types of buildings with elevators serving many families ; twin-corridor type or single-loaded corridor type. And they had more sense of territory and less fear of crime than who in the other types in the indoor common areas. (2) Housewives in the "two-families" type of building exchanged greetings more neighbors in their own building than who in the single-loaded corridor type. (3) In the "two-families" type of building, the ratio of crime in the indoor common areas was slightly less than that in the other types of buildings, but those differencies was'nt stastically significant. (4) Housewives in the "two-families" type of building evaluated this type of building high because of not only high security but also well-ventilation, protection of privacy, establishment of balconies facing north, and lookout of their children on the grounds from their units.
