UN-Habitat is promoting a new urban planning paradigm that calls for planning in advance at the scale of expected development of cities with a better integration of urban uses – housing, business, retail, recreation, education, agricultural, amongst others. The aim of this paradigm shift is to achieve adequate urban densities to minimise the impact of urban sprawl, improve mobility and reduce greenhouse emissions. The ultimate goal is to attain the social, economic, environmental and cultural sustainability of cities.For this development-oriented competition, participants will need to contact the owners of the housing stock to jointly select a typical mass housing complex for revitalization.
