This paper explores the redevelopment potential of ageing and underutilised public housing properties in the middle suburbs of major Australian cities. State governments lack strategies for the renewal of this housing in the current fiscally constrained environment.
Due to the unsustainable nature of urban sprawl, Australian metropolitan strategies have increasing been pushing for increased levels of infill: the redevelopment of existing urban (typically residential) land. However, the current infill models of Brownfield and lot-by-lot redevelopment are largely incapable of generating the volume or range of future housing needs.
A major challenge for urban Australia and its fast growing cities in particular is the provision of an adequate supply of appropriately located, affordable and sustainable housing across a range of dwelling types. A related challenge involves attempts by the metropolitan planning agencies in the capital cities to restrict residential sprawl and deliver more compact cities.
Metropolitan planning and development of Australia’s cities has been strongly influenced by what could be termed the “North American model” of low-density, car-dependent suburban development on greenfield master-planned housing estates. But this is all set to change.
In an era of smart cities, planning support systems (PSS) offer the potential to harness the power of urban big data and support land-use and transport planning. PSS encapsulate data-driven modelling approaches for envisioning alternative future cities scenarios. They are widely available but have limited adoption in the planning profession (Russo, Lanzilotti, Costabile, & Pettit, 2017).
Australian cities, especially the four big ones, are growing rapidly. Their growth enables many agglomeration benefits and creates many social and environmental impacts. This report examines new approaches to resolving how we can grow to create new opportunities for our children and grandchildren but at the same time manage the social and environmental issues associated with such growth.
Cities are comprised of hundreds of thousands, if not millions, of small parcels of individually owned land. The fractured nature of these tenures, combined with the network of administrative and infrastructural bodies governing them, makes any form of significant and coordinated planning change incredibly complicated, if not untenable.
Australia’s cities face significant social, economic and environmental challenges, driven by population growth and rapid urbanisation. The pressure to increase the availability of housing, including a move to a more compact urban form, will lead to greater levels of high-density and medium-density stock.
Pressures for urban redevelopment are intensifying in all large cities. A new logic for urban development is required – green urbanism – that provides a spatial framework for directing population and investment inwards to brownfields and greyfields precincts, rather than outwards to the greenfields
