Abstract
The purpose of this article is to clarify relationship between inhabitants' relations and attributions of building such as scale, location and so on, in urban largescale condominiums. For this purpose, we carried out interviews and questionnaires to inhabitants of condominiums. By interviews, opportunities to get to know other inhabitants were divided into four groups; spatial proximity, existence of mediator, participating to the governance and participating to events and circles. By cluster analyses from a viewpoint of the number of close friends and acquaintances, condominiums were divided into four groups. We found that attributions of buildings were different in each groups.
