Istanbul exhibits all major characteristics of a metropolitan area and urbanization is increasingly appearent. In construction projects of new housing areas, walled residential quarters with restricted access increased remarkably to overcome the social and physical dangers of the densely populated areas. This study explored the concerns of 97 parents for their children’s outdoor use in a residential quarter separated physically and secured from the outside neigbourhood. In this qualitative study, face-to-face interviews with the parents having elementary school children were interviewed. Parents were asked to describe their children’s play attitude to use the residential quarter. Open-ended questions were designed to explore their permission rules and concerns. Key demographic questions were also asked at the end of the interview, including parents’ level of education, gender of children and income level. Parents reported on four themes to assess the range of influences on safety and environmental factors, level of independence, play facilities and social aspects. By asking the safety and environmental factors, children’s access to quarter facilities, internal transportation, pedestrian activity and security installations were questioned. Interview questions revealed the conditions and the level of independence to go places in the residential quarter. The content of the play facilities indicated the suitability of the facilities to the children in gender and age differences and its relation to the size of the courter. Finally the social aspects were questioned to evaluate the impact of friends and neighbour relations on play activity of the children. The transcripts of the interview indicated that safety of the residental court is threatened by the possible emergent vehicle access into the courtyard. Majority of parents agreed that the court can be accessible by the visitors though it’s gated. These factors influence the permission boundaries to play and invoke the parental supervision. Hence the level of independence is limited to the number of places close to the residential unit. Compared with parents of younger children (6-8 years), parents of older children (9 years and above) more often reported that they allowed their child greater independence. The findings of the present study regarding parental concerns raise the questions on the security of gated communities and their impact on play activity of children.
