S Social cohesion is one of the important elements in the concept of community inhousing planning or design. Social cohesion can be created on a neighborhoodscale with a relatively homogeneous structure of residents. Generally, residents ofgated housing are homogeneous in terms of their income level. The literature ongated housing communities mostly focuses on the social consequences, not muchrelated to the spatial aspects. The purpose of this study is to identify the level ofsocial cohesion of residents in gated housing and the spatial factors that influenceit. These factors include neighborhood size, the availability of facilities, and thehousing layout. The research design uses a questionnaire survey method. A sampleof 80 respondents came from residents of two gated housing units, namely EmeraldView and Taman Provence. Both were chosen because in general they have themain features of gated housing characteristics and a homogeneous residentstructure, namely the upper middle class. The analysis technique uses multiplelinear regression with Smart-PLS software. The results showed that the level ofsocial cohesion was classified as moderate, and that significantly influenced by thethree spatial factors. However, only neighborhood size that have a positive effecton increasing social cohesion among residents. Meanwhile, the others factors havea negative effect. This is because the size of the neighborhood described by thenumber of residential units is classified as dense so that residents tend to be moreintimate with their neighbors. Meanwhile, the availability of facilities and housinglayouts described by the road network pattern is still not in accordance with theneeds of residents to interact.
