Design competition challenges cookie-cutter outer-suburban housing template

We're creating car-based environments that are perpetuating the problems.
Urban designer on why standard greenfields housing ignores heat, biodiversity, and walkability.
Mark

Why does a design competition matter if there's no guarantee the winning design gets built?

Mimi

Because it shifts what people think is possible. For 20 years, greenfields housing has followed one template because that's what the economics and engineering standards demanded. A competition says: there are other ways. It gives emerging architects a platform to prove it, and it gives developers and planners permission to imagine differently.

Mark

But the real constraint is density targets set by government. How much freedom did these designers actually have?

Mimi

Less than they might have wanted, more than standard developments get. They had to hit the housing numbers. But within that, they could choose to cluster instead of sprawl, to share instead of privatize, to restore instead of clear. That's where the real innovation happened—not in breaking the rules, but in working within them creatively.

Mark

The article mentions that urban heat in growth suburbs is 10 degrees hotter. Is that a solvable problem through design, or is it just the cost of density?

Mimi

It's solvable through design, but it requires intention. Trees, shade, water features, permeable surfaces instead of asphalt—all of these cool a place down. The problem is that standard greenfields development ignores them. The winning designs put them at the center. Whether that approach scales depends on whether developers see it as profitable, not just possible.

Mark

What does it mean that the Coalition wants to ramp up greenfields approvals while Labor wants to densify established suburbs?

Mimi

It's a choice between two different problems. Greenfields are cheaper and faster to develop, but they sprawl the city outward and require infrastructure that lags behind. Densifying established suburbs is harder politically and economically, but it uses existing infrastructure. The competition suggests a third option: greenfields that are designed like centers, not edges. But that requires political will and developer buy-in, neither of which is guaranteed.

Mark

The article mentions that infrastructure hasn't kept pace with growth. Can better design fix that?

Mimi

Design can make existing infrastructure work harder—walkable neighborhoods need less transport, mixed-use centers need fewer car trips. But it can't conjure schools and hospitals that don't exist. That's a government problem, not a design problem. The competition is about making greenfields liveable within the constraints we have. It's not a substitute for planning at the city scale.

  • Melbourne is adding people faster than any Australian city, and most of them are landing in outer suburbs that are hotter, car-dependent, and stripped of nature — a pattern research shows runs more than 10 degrees warmer than surrounding areas.
  • The Urban Design Forum launched a $15,000 competition in August to directly challenge this template, using a real developer-owned site near Ballan station as the proving ground.
  • Winning entries discarded driveways, clustered homes around shared courtyards, and made ecological restoration — including critically endangered native grassland — the foundation of the design rather than an afterthought.
  • Despite the ambition of the entries, the developer made no commitment to build any of them, leaving the competition's impact suspended between inspiration and irrelevance.
  • A November state election now holds the deciding vote: Labor's densification agenda versus the Coalition's greenfields acceleration, with two decades of failed diversion policy already on the scoreboard.

On the outer edges of Melbourne, where paddocks are becoming suburbs faster than anywhere else in Australia, a design competition has quietly posed a question the city has long avoided: what if the template for new housing was built around people rather than cars? The Urban Design Forum's August competition asked emerging architects to reimagine a six-hectare site near Ballan station, and the answers that came back — clustered homes, shared land, restored grasslands — suggest that the sameness of Australia's greenfields estates is a choice, not an inevitability. Whether that choice changes now rests less with designers than with voters, as a November state election will determine whether Melbourne continues its outward march or turns inward toward its established heart.

Melbourne is racing toward nine million people, and most of that growth is landing on its outer fringe — in greenfields estates where paddocks become suburbs almost overnight. Four of Australia's five fastest-growing suburbs sit on Melbourne's edge, and they share a familiar look: wide streets engineered for garbage trucks, houses on shrinking blocks, no trees, no shade, no reason to leave the car. This sameness is the product of economics and engineering standards, not inevitability. Research from 2024 found that Melbourne's growth suburbs run more than 10 degrees hotter than surrounding areas — a consequence of canopy-free streets and relentless hard surface.

In August, the Urban Design Forum launched a design competition to challenge that template. The site was a six-hectare parcel beside Ballan train station, 78 kilometres west of the city — real land owned by a real developer, slated for housing. The brief asked competitors to imagine something different: a neighborhood integrated with nature, adapted to climate, designed as a place rather than an edge.

The winning entry, A Seed for Housing, began with land restoration. The site once supported native grassland — now critically endangered, with 99 percent cleared across Victoria's volcanic plains. The winning team made grassland rehabilitation their first act, proposing a natural pool fed by filtered drainage channels and surrounded by native grasses. Clustered duplex homes arranged around shared outdoor space replaced the standard detached-house-on-a-block model, and private driveways disappeared entirely in favour of a shared carport. A runner-up entry tackled developer economics directly, narrowing street widths to cut costs and introducing shared driveways to reclaim wasted space. A student co-winner oriented a double-sided pavilion toward both a local oval and a wetland visited by migratory Latham's snipes.

All of these designs worked within real constraints — state density targets, shrinking lot sizes, developer viability. Melbourne's median lot in growth corridors has already fallen from 441 square metres in 2015 to 352 by 2025. The competition entries responded by replacing private yards with communal open space, a shift that reframes what suburban living could mean.

But none of it is guaranteed to be built. The developer contributed to the prize pool without committing to construct anything. The deeper question now belongs to politics: a November state election will pit Labor's push to densify established suburbs against the Coalition's promise to accelerate greenfields approvals. Two decades of policy aimed at redirecting Melbourne's growth inward have largely failed — more than half of new housing in 2025 was still built in growth corridors, and infrastructure has not kept pace. The competition showed what greenfields development could become. Whether Melbourne chooses it remains an open question.

Melbourne is growing faster than any Australian city, racing toward nine million people. Most of that growth is happening on the urban fringe—in greenfields developments where paddocks become suburbs almost overnight. Four of Australia's five fastest-growing suburbs are on Melbourne's outer edge, and they all look the same: wide streets built for garbage trucks, houses on shrinking blocks with minimal yards, no trees, no shade, no reason to step outside your car.

This sameness is not accidental. It is the product of economics and engineering standards. Greenfields housing is cheaper to build and simpler to develop than infill projects in established neighborhoods. Street designs follow vehicle movement patterns. Driveways proliferate. The result, according to Andy Fergus of the Urban Design Forum, is a landscape that ignores heat risk, lacks canopy trees, offers no space for children to move freely, and perpetuates car dependency. Research from 2024 found that urban heat in Melbourne's growth suburbs runs more than 10 degrees hotter than surrounding areas.

In August, the Urban Design Forum launched a design competition to challenge this template. The prize pool was $15,000. The site was a six-hectare greenfields parcel on the southern side of Ballan train station, 78 kilometres west of Melbourne on the Ballarat line—land owned by developer Ample and slated for housing. The brief asked competitors to reimagine what a new neighborhood could be: integrated with nature, adapted to climate change, designed as a center of community life rather than an ever-expanding edge.

The winning entry, titled A Seed for Housing, began not with houses but with land restoration. The site once supported native grassland that blanketed Victoria's western volcanic plains. That grassland is now critically endangered, with 99 percent cleared. The winning team—including Audrey Avianto and Tom Hastie—made grassland rehabilitation stage zero of their design. They proposed a natural pool fed by filtered drainage channels lined with native grasses. Beyond the pool sat clusters of duplex houses arranged around shared outdoor space, with no private driveways. Residents would park in a common carport nearby. The pool served dual purpose: it managed stormwater and gave the estate something compelling, something that made people want to live there.

A runner-up entry called Common Interest tackled the economics directly. Oliver Harris explained that his team designed for developer viability and affordable housing. They narrowed street widths—a significant cost saving—and introduced shared driveways that eliminated unnecessary crossovers and driveway space. The student category co-winner, Blackwood Fields, featured a double-sided pavilion: one face toward the local oval, the other toward a wetland where bird watchers could observe Latham's snipes, migratory birds that travel between Japan and Australia's southeast coast.

These designs worked within real constraints. State government density targets meant the estate had to accommodate a certain number of dwellings. Lot sizes in Melbourne's growth corridors have already shrunk by just over 20 percent in a decade, from a median 441 square metres in 2015 to 352 by 2025. Most winning entries addressed this by clustering housing and replacing private yards with communal open space—a radical shift from the detached-house-on-a-block template that dominates greenfields development.

But there is no guarantee any of these designs will be built. Ample contributed to the prize pool but made no commitment to construct the winning entry. The future of Melbourne's growth pattern now depends on politics. In November, voters will decide between Labor's push to densify established suburbs and the Coalition's promise to accelerate greenfields approvals. Urban planner Rob Burgess has studied 20 years of state policy aimed at diverting growth away from the fringes. It has mostly failed. More than 50 percent of new housing for Melbourne was built in growth areas in 2025, despite a long-standing target of 70 percent in established suburbs. Infrastructure—transport, schools, hospitals—has not kept pace with that growth, creating social problems that cannot be solved by engineering housing patterns alone. The competition was an attempt to show what greenfields development could become. Whether Melbourne's next chapter will embrace that vision depends on which way the state swings.

When you're turning a paddock into a new neighbourhood, nothing is set in stone, so the opportunity to do something that really transforms the quality of liveability is pretty key.

There's a very simplistic position as to what our city should be, which doesn't in any way align with the practical realities of the way in which development occurs, and I think that is now coming at a significant cost.
