Australia's housing shortage has prompted renewed calls for innovative solutions, with property expert Kim MacDonald advocating for increased suburban density as a key strategy to unlock vacant blocks of land.
The Case for Suburban Density
MacDonald, a prominent figure in the property sector, argues that by allowing higher-density developments in established suburbs, local councils can free up underutilised land parcels that are currently sitting idle. This approach, she says, could significantly boost housing supply without encroaching on greenfield sites or requiring extensive new infrastructure.
"Many suburbs have pockets of vacant or underdeveloped land that could accommodate townhouses, duplexes, or low-rise apartments," MacDonald explains. "By updating zoning laws and streamlining approval processes, we can make better use of this space."
Addressing the Housing Crisis
The current housing shortage has been exacerbated by population growth, supply chain delays, and rising construction costs. Traditional approaches, such as expanding urban fringes, have often proven slow and costly. MacDonald suggests that infill development—building within existing urban areas—offers a more efficient path forward.
"We need to think creatively about where we can add homes," she says. "Vacant lots, underused car parks, and even large backyards could be transformed into new housing opportunities."
MacDonald's proposal aligns with broader trends in urban planning, which increasingly favour densification over sprawl. Cities like Sydney and Melbourne have already implemented similar strategies, but many suburban councils remain resistant to change.
Challenges and Opportunities
While the idea has merit, experts caution that implementation requires careful management. Issues such as community opposition, infrastructure capacity, and design standards must be addressed to ensure new developments enhance rather than detract from neighbourhood character.
"It's not about cramming high-rises into every street," MacDonald clarifies. "It's about thoughtful, context-sensitive density that respects local amenity while meeting housing needs."
Proponents also highlight the environmental benefits of denser suburbs, including reduced car dependence and preservation of green spaces on city outskirts.
As the housing crisis deepens, MacDonald's call for suburban density is gaining traction among policymakers and developers alike. Whether it becomes a widespread solution remains to be seen, but the conversation is shifting towards more creative uses of existing urban land.
