ABSTRACT: The proliferation of master planned estate development has generated considerable debate regarding the exclusive nature of these developments. Master planned estates appear to find considerable support from planners and governments, as well as the residents within these new estate areas. The research presented here analysed the constructions of exclusivity for a master planned estate (Glenmore Park) and the extent to which the constructed identity for Glenmore Park resulted in socio-spatial polarisation within western Sydney. The research concluded that socio-spatial polarisation is intensified through the development of master planned estates. This paper focuses specifically on the future of master planned estate development in Australian cities, particularly given that master planned estates are a favoured form of residential development even though, as is argued in this paper, they have quite obvious implications for social equity. A concluding discussion on the revived urban village concept, the discourse used at Glenmore Park, offers a warning for this current urban planning paradigm, particularly of the associated social outcomes. Research agenda’s are proposed in the last instance.
