This report proposes a scenario which identifies how to match land supply to expected demand for dwellings. It proposes one approach to preparing for a doubling of the population of Melbourne. It challenges the conventional view that most demand should be met in expanding outer suburbs, a model of urban form based on detached housing on relatively large lots and separated uses. The reality of the new dwelling market in Melbourne is that high-rise apartments and outer urban housing limit the choices of large numbers of people to inadequate, poorly serviced housing types often far from employment. The location and most suitable types of housing should be intricately linked with the effective functioning of the city through access to employment and service provision, avoiding inequitable outcomes and increased social division and protecting amenity and providing high quality urban design and environmental conditions.
