The article deals with social housing implemented by the BNH (National Housing Bank) in Brazil in order to subsidize future social housing production by government agencies. It aims at understanding how the layout of housing schemes related to size, spatial configuration and location, can affect social interaction among dwellers as well as interaction between the housing scheme and its urban context.Methodological procedures included archives information, physical measurements, observation of behaviour, mental maps with interviews and questionnaires. Following the perceptive approach adopted, user satisfaction and environmental behaviour are employed as indicators of environmental performance and social interaction. The layout characteristics studied are related and influence the type and intensity of social interaction between residents and its urban context. Furthermore, it is verified if the integration of scheme in the urban context, due to its configuration, helps residents integrate into the district/ city and feel recognized as belonging to the city, as well as increase satisfaction with their place of residence. It is intended to provide theoretical subsidies that might contribute to implementation of housing schemes that will encourage social interaction among dwellers and between the housing scheme and its surroundings, based on the premise that it is an essential quality of cities to fulfill the role of place of meeting and social exchange, promoting contact between people. That is, urban structures might stimulate the occurrence of interaction among citizens as a consequence of density, level of permeability between public and private spaces, urban diversity and urban vitality.
