Hong Kong’s residential neighbourhoods are characterised by high-rise, high density estates with limited public open spaces, as a result of limited regulation and land resources. Tuen Mun new town, due to its remote location and affordable housing, has a mixed demographic consisting in part of a range of immigrant families from different cultural and ethnic backgrounds. In the context of this social diversity, the lack of specifically designed public spaces suited to different cultural needs may decrease neighbourhood relations and a sense of belonging in the city. The study presented here analyses the characteristics of individual and group activities of Tuen Mun residents, documenting the composition of public space in residential areas. It employed field observations, questionnaires, and GIS mapping to map the shortest routes to desired locations. By correlating the cultural activities of diverse residents with physical characteristics of public space features, the study identifies elements and atmospheres that are conducive to spatial appropriation for cultural activities. The study produces insights about how to adapt existing or newly planned housing estates and neighbouring public spaces to better support diverse residents and promote social and cultural integration.
