Comparative case study research in two prototype model sustainable neighbourhoods, Fréquel Fontarabie in Paris (France) and Dockside Green in Victoria (Canada), sheds new light on questions of ecogentrification in urban redevelopment cycles. The two cases are chosen for their superficial similarities, as mutual but independent frontrunners of the international movement to build sustainable neighbourhoods.
