Why the housing shortfall has become a delivery problem, not only a planning one, and why offsite construction raises the stakes.

Australia’s Housing Accord asks for 1.2 million new homes in five years, roughly 240,000 a year. In the first full year, the country completed around 174,000, a shortfall of about 27 per cent, and the National Housing Supply and Affordability Council now projects the target will be reached more than a year late.
The public debate treats this as a pipeline problem: planning, land, finance and approvals. The industry has begun to name the conversion gap as well, the widening distance between what gets approved and what actually gets built. But almost every explanation for that gap has stayed outside the firm, in construction costs, credit and project feasibility.
First findings published through a research initiative of Western Sydney University and Infinikey Consulting look where the debate has not: inside the delivery businesses themselves, at whether they can execute the approved pipeline at the required speed, cost and quality.
What the fieldwork found
Wave one combined the public record, including the Productivity Commission’s finding that construction labour productivity has roughly halved in three decades, with primary research inside 12 NSW firms spanning development, head contracting, civil, trade and project management. Each firm completed a structured questionnaire across four operating-control dimensions, then a project walk-through interview that tested reported confidence against demonstrated control.
The pattern was consistent, and uncomfortable. Firms are stronger at routine execution than at live visibility. Nine of the 12 report their standard delivery process mostly holds, yet only one of the 12 consistently sees its live commercial position while building.
Physical progress is tracked in real time; commercial truth is reconstructed afterwards, from invoices, claims and end-of-month reconciliations. Decisions route through a small group of senior people, and none of the firms consistently reported that problems surface early. At the margins typical of residential building, that lag is the difference between a profitable project and a loss found too late to prevent.
Six failures, one pattern
For this masthead’s readers, the sharpest section of the paper may be the offsite one. The research examines six offsite business failures: Strongbuild in 2018, and Viridi Group and Cross Laminated Offsite Solutions in 2024 in Australia, alongside Katerra, Ilke Homes and Legal and General Modular internationally.
The Fifth Estate‘s reporting on Strongbuild and Viridi forms part of the evidence base. The finding that unites all six is the same: the production capability was still working at the point of failure. The factories were fine. What failed was the business model around them, through demand concentration, factory underutilisation against high fixed overheads, and working capital misaligned with how construction gets paid.
That record matters now because Australian governments have converged on prefabrication as a primary lever for housing delivery. New South Wales has legislated a chain of responsibility for prefabricated construction and backed it with budget funding and an industry expansion program, and the Australian Building Codes Board is consulting on a national voluntary certification scheme for manufacturers.
The Productivity Commission’s estimates, up to 20 per cent lower cost and up to 50 per cent faster construction, explain the enthusiasm. But those figures are a ceiling, not a default. They are available to firms whose operating models can sustain continuous factory throughput, frozen designs and a smoothed demand pipeline. They are not an automatic outcome of adopting the method.
The assurance gap
There is an assurance gap worth naming. Certification will assure the module and the manufacturer’s process: the product is compliant, the systems are sound. Nothing in the emerging framework assures the business behind the module, its order pipeline, its factory economics or its working capital. Every failed firm in the paper’s table could have passed a production system test on the day it entered administration.
The deeper reason offsite raises the stakes is structural. Conventional construction absorbs a weak operating model, because improvisation on site patches the gaps. Industrialisation removes the improvisation by design. Offsite construction therefore punishes an unchanged operating model faster and harder than site-based delivery ever did. Changing the method without changing the model does not remove the bottleneck. It relocates it.
A management question, not only a policy one
None of this argues against planning reform, and none of it argues against prefabrication. It argues that conversion, from approval to completed home, has become a management question as much as a policy one. The first findings, the evidence behind them, and a delivery maturity model that locates a firm on the spectrum from heroic to systematised delivery are set out in the full paper, which is free to download.
The findings will be presented and debated by a senior industry panel at a briefing in Parramatta on 30 September.
