Discover how prefabricated timber frame and truss systems are transforming Australia’s construction industry – boosting productivity, reducing waste, and tackling the housing crisis head-on. Read the full article to learn how Big River Group is leading this shift with smarter, more sustainable building solutions.

As Australia targets 1.2 million new homes, Big River Group and the frame and truss sector are driving a new era in sustainable construction.

As the Australian construction sector responds to ongoing labour shortages, tighter margins, and the increasing push for sustainable building practices, frame and truss manufacturing is undergoing a quiet revolution. What was once a traditional trade has become a centrepiece of innovation, driven largely by digital design tools, offsite manufacturing, and a focus on reducing waste and boosting productivity.

Prefabrication or ‘prefab’ isn’t new, but its role in residential and commercial building has taken on new urgency. In a climate of material volatility and unpredictable weather, prefabricated frames and trusses are helping builders take back control of timelines and budgets. Manufactured in controlled environments and tailored to project-specific requirements, today’s precision-engineered timber frames and trusses offer more than convenience. They streamline the sequencing of trades, reduce the risk of onsite errors, and improve safety by limiting time spent working at height.

“Builders are looking for ways to remove variables from the jobsite,” says Helen Awali, Executive General Manager – Construction at Big River Group. “Prefabrication helps do that, it’s about managing risk and delivering more predictable project outcomes.”

In an environment where weather, supply, and workforce conditions can shift weekly, builders are leaning on prefabrication not just for productivity but for peace of mind. By reducing the number of trades needed onsite and limiting time spent coordinating multiple moving parts, prefab systems give project managers greater control. For many, it’s not just about faster builds, it’s about lowering stress levels, simplifying site logistics, and having greater confidence in delivering on schedule. With the growing pressure to do more with less, this kind of predictability is becoming one of the industry’s most valuable assets.

Prefab is also helping address the skills shortage in other ways by creating clearer workflows and reducing reliance on site-based problem solving, it allows younger trades and apprentices to step into more structured, tech-integrated roles. Working from detailed plans and factory-controlled components helps them build capability faster, with fewer errors and a more consistent understanding of sequencing. It’s a shift that’s supporting both quality and the next generation of the workforce.

Across the industry, there is growing interest in integrating AI-assisted design and exploring compatibility with BIM systems-tools that can provide real-time visibility into how framing intersects with services and other structural components. These emerging technologies are shaping what the next generation of prefabrication could look like, particularly in more complex or multi-residential builds.

Helen explains, “If you can identify a clash before the frame is even built, you’re not only saving time, you’re protecting your margin and avoiding conflict between trades. That’s what builders need right now.”

Sustainability is also front of mind. Manufacturing in controlled settings minimises timber offcuts, improves recycling, and allows for smarter stock control, an important factor given the rising cost of materials and tightening waste regulations across the country.

Helen says it’s an area where frame and truss manufacturers are making significant progress. “At our Breakwater facility, we’ve reduced landfill waste by more than 90% by repurposing timber offcuts and targeting recycling of plastics and metals,” he explains. “Reducing waste isn’t just good for the environment, it’s good for business. We’re seeing more builders factor that into their project planning and supplier choices.”

This innovation comes at a critical time. Under the National Housing Accord, the Albanese government has committed to building 1.2 million new homes by 2029. To support this goal, more than $54 million has been pledged to accelerate the adoption of prefabricated and modular housing, including $49.3 million for state and territory governments to scale up offsite construction, and $4.7 million to develop a national certification system for prefabrication. The investment is designed to increase industry confidence and streamline adoption at scale.

Helen sees this momentum as essential to meeting both policy and productivity goals: “What we’re seeing at the federal level is a genuine recognition that to build faster and more sustainably, we need scalable solutions. Prefab is one of the smartest tools we have.”

For companies already operating at the forefront of prefabrication, including frame and truss manufacturers like Big River Group, this national momentum validates years of investment in design technology, offsite manufacturing, and waste reduction. It also reinforces the critical role prefabricated timber can play in meeting Australia’s housing needs efficiently, sustainably, and at scale.

As the sector looks ahead to new codes, faster builds, and more resilient housing, innovation in timber frame and truss will continue to play a critical role, not just in shaping structures, but in shaping how we meet the country’s most urgent housing and workforce challenges.

Australia is currently experiencing a significant housing shortage, with the construction industry under immense pressure to deliver homes more rapidly, sustainably, and affordably. Recent forecasts by Master Builders Australia indicate that the nation is projected to fall short of the National Housing Accord target of 1.2 million new homes by over 166,000 dwellings between July 2024 and June 2029. As the search for practical solutions intensifies, innovative building materials like MaxiWall, an Autoclaved Aerated Concrete (AAC), from Big River Group, are playing a key role in addressing these challenges, offering faster build times, reduced environmental impact, and greater affordability for developers and homeowners.

The construction industry is entering a new era of innovation, driven by the need for greater efficiency and sustainability. This shift is driving the adoption of advanced building techniques and materials by the industry that not only accelerate construction but also minimise environmental impact. These trends are setting a new standard for Australian construction, aligning with the urgent need to deliver housing solutions that meet the demands of a growing population while ensuring we have a sustainable future.

“Sustainability in construction is no longer optional – it’s essential,” said Ray Ferretti, Executive General Manager – Construction of Big River Group. “MaxiWall is designed with this in mind, offering a greener alternative to traditional brick and block building materials. By reducing greenhouse gas emissions during production and improving energy efficiency in homes, MaxiWall is not only a smart choice for the environment but also for homeowners looking for long-term savings.”

MaxiWall offers significant advantages for both homeowners and the build trade, making it a practical and versatile choice in today’s residential market. For builders, the lightweight panels streamline construction, with each one equivalent to laying approximately 75 bricks. This reduces labour demands and shortens construction timelines, enabling faster project completion. Additionally, installation requires no wet trades, with the panels able to be installed by carpenters already on-site, simplifying coordination and reducing costs without compromising installation or product quality.

The benefits of MaxiWall extend well beyond the construction phase for homeowners. Its sustainable design prioritises energy efficiency and environmental responsibility, using 60% less embodied energy than traditional masonry and produce 55% less greenhouse emissions than concrete and brick.

Ferretti added, “With superior insulation qualities compared to other masonry products the amount of energy required to heat or cool a home is greatly reduced, ensuring a more comfortable living environment year-round, savings to homeowners and ongoing environmental benefits.”

Particularly important in multi-residential housing, semi-detached and terraced houses is MaxiWall’s excellent acoustic insulation.
