Australia is projected to fall more than 260,000 dwellings short of its 1.2 million target by 2029.¹

The crisis isn’t just about supply; it’s about how we fund the methods that can deliver homes faster. That’s why the Commonwealth Bank’s recent move to create financing options for prefabricated housing is so important. It acknowledges that traditional lending models are out of step with how housing is evolving, and it opens the door to scaling modern methods of construction (MMC).

But as the spotlight falls on modular and volumetric housing, there is a risk that we overlook the most established off-site method of all: precast concrete.

 

Why precast belongs in the finance conversation

Unlike newer forms of MMC, precast is hardly experimental. Australia already has the factories, workforce and standards to deliver it at scale. Precast panels are made in controlled factory environments, ensuring consistent quality. They are durable, fire resistant and thermally efficient, and they integrate easily with conventional construction.

Yet precast manufacturers face the same financing barrier as modular builders: the bulk of their costs are incurred upfront, long before panels are craned into place. Traditional bank models – tied to progress payments on site – simply don’t fit. Without finance that reflects the realities of off-site manufacture, precast remains under-utilised in the very areas where it could have the greatest impact: social housing, affordable housing, and medium and high density developments.

This disconnect is holding us back. Social housing providers, for example, could be commissioning thousands of high-performing homes with precast right now… if only the financing model matched the build model.

 

Why precast is lower risk than modular

It’s worth noting the contrast. If banks see value in modular housing – still relatively new to the mainstream – then precast, with decades of proven performance, is an even safer bet. The method is already trusted in infrastructure, high-rise apartments, and public buildings across the country. It has a proven track record for durability and lifecycle performance, which means lower maintenance costs and longer asset life for owners.

Add to that its thermal efficiency, which translates to reduced energy bills, and its ability to improve construction productivity by shifting work into factories, and the case for precast becomes hard to ignore.

 

A call to action

Talk to any precast manufacturer and you’ll hear the same frustration: the panels are ready, the systems are proven, but finance is holding projects back.

It is remarkable that precast is not being more widely adopted in medium and high-density housing given its obvious strengths. The opportunity is right under our noses: a method that can meet urgent housing demand and lift construction sector productivity in ways few other approaches can rival.

Banks must expand their prefab finance models to cover precast. Governments should explicitly support this by recognising precast in MMC funding programs. And industry must be ready with standardised systems that align with these financing frameworks.

Australia cannot afford to overlook precast in the race to solve the housing crisis. With finance reform now on the table, precast shouldn’t be an afterthought – it should be at the centre of the conversation.
