This article examines infill housing development in Melbourne, Australia's second largest and fastest growing capital city. It highlights the existence of two infill segments - brownfields and greyfields - each with distinctive patterns of development that need to be better understood if urban regeneration is to figure significantly in delivering more liveable and sustainable cities.
This project sought to address three areas of policy concern in relation to dispersed and ageing public housing properties in inner and middle ring suburbs: how to find new ways to accommodate population increases; how to create affordable and diverse housing options; how to manage ageing housing stock; and how to maximise the use of existing infrastructure and amenity.
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.
The intensification of development that is required in established and occupied inner and middle suburban greyfield areas (retrofit) is the great challenge for our fast-growing Australian cities. The scale of urban regeneration required over the next 30 years has the potential to reduce carbon emissions, improve housing affordability and reduce urban sprawl.
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.
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 housing availability will lead to greater levels of high-density and medium-density stock. However, there is enormous political and community pushback against this.
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
