Sydney's housing crisis is real, and the state government's determination to solve it through aggressive density is measurable. But a development proposal in Concord West offers a cautionary lesson in what happens when density incentives become a blank cheque for developer ambition.
The scheme under discussion illustrates how planners and developers are responding to NSW planning reforms that streamline approvals for projects near transport hubs.What began as a proposal for 698 apartments at the Concord West site evolved into plans for 1,336 homes through the application of planning bonuses.The scheme from Billbergia and Metrics involves converting vacant warehouses into eight residential towers at 1 King Street, next to Concord West train station, creating 1,300 new homes.
The mechanism underlying this expansion is straightforward fiscal policy.Projects must include a minimum of 15% affordable housing by gross floor area to access development bonuses, with up to a 30% bonus available in floor space ratio and building heights for projects with 15% affordable housing. When the maths work, developers build more. When planning authorities permit it, they do so believing they are meeting state housing targets.
The logic is defensible.The NSW Productivity Commission has calculated that if governments permitted average building heights of 10 storeys instead of seven, and 100 units instead of 70 per building, an additional 45,000 dwellings could be supplied without extra land. From this perspective, density bonuses are not excess; they are essential arithmetic.
Yet the Concord West project also reveals the limits of relying purely on density incentives.The developers requested amendments allowing maximum heights of up to nearly six times what they were previously, as well as changes to floor space ratios. This is not incremental infill. It is transformation on a scale that raises legitimate questions about infrastructure, parking, streetscape impact, and whether density divorced from careful place-making creates liveable communities or merely maximises developer returns.
The tension is real and not easily resolved. Housing supply undoubtedly matters. Empty warehouses near transport nodes are arguably better used as residential precincts than as legacy industrial space. Affordable housing contributions embedded in density bonuses are preferable to projects with zero public benefit. And younger households, essential workers, and first-home buyers all face a market that has priced them out of inner-west suburbs through scarcity.
But there is a competing consideration.NSW planning reforms override restrictive local council zoning that has effectively banned medium-density housing types in many areas, with only two of 33 councils in Greater Sydney allowing terraces and townhouses in low-density zones, and residential flat buildings prohibited in 60 per cent of all medium-density zones. This is evidence of genuine undersupply caused by local planning constraints. Removing those constraints should mean proportional increases in housing. It should not mean projects expanding beyond reasonable proportion when bonuses are available.
The Concord West case also raises a fiscal question that centre-right thinking usually emphasises: whether the incentive structure is fit for purpose. Developers are rational actors responding to rational incentives. If bonuses are uncapped, projects will expand to capture them. If infrastructure contributions are fixed or negotiable, communities bear costs that developers do not. This is not developers behaving badly; it is the system working exactly as designed. The question is whether the design is sound.
The joint venture partner notes that the project aligns with state and federal government housing priorities and reflects commitment to supporting economic growth and job creation. This is accurate. Yet from a pragmatic governance perspective, housing targets should be met through a portfolio of projects of varying densities and scales, not by maximising every lever in a single scheme.
A more sophisticated approach would involve setting infrastructure capacity benchmarks, scaling bonuses to local absorptive capacity rather than offering blank percentage increases, and requiring genuine place-making commitments alongside density. Public benefits should be specific, local, and proportionate. The fact thatthe developers have offered voluntary planning agreements including road upgrades costing about $9.2 million and stormwater drainage contributions of $808,764 is welcome but raises the question: should essential infrastructure upgrades require negotiation, or should they be built into the capacity analysis before bonuses are granted?
Housing supply matters. So does building communities that function. The Concord West proposal sits somewhere between these two imperatives, and it deserves scrutiny not as an obstacle to housing, but as evidence that blunt incentive mechanisms may not be the most efficient way to align developer ambition with public interest.
