Australia faces a critical housing shortage impacting affordability and social wellbeing, with a national target of 1.2 million new homes by 2029. More affordable and sustainable homes are needed that better respond to individual customer needs and locations. Prefabricated construction, supported by $54 million in the 2025-26 federal budget, is an emerging solution but still constrained by regulatory complexity, financing access, competition with traditional practices and high customisation costs. Local renewable resources can strengthen this sector and help fill a projected market gap for construction timber of 50% by 2050, including $311M/year in imported Engineered Wood Products (EWPs) alone.
A substantial volume of under-utilised native Australian timbers, particularly from thinning in state forests and hardwood plantations, offers potential for significantly more efficient use through recently adopted spindeless veneering processing technology and Engineered Wood Product (EWP) manufacturing methods, developed in local Forest Products Innovation R&D over the past decade. This study builds on a circular economy prefabrication factory that maximised the use of native cypress pine and pioneered an industrial trial using this processing technology. The operation ceased in late 2023 following the passing of the director. Its construction practices aligned with multiple UN Sustainable Development Goals, including SDG12 - Responsible Consumption and Production (Matthews, 2024). Based on a case study on adaptable modular design with value-added native/mixed species prefab components, this applied research investigates market potential, scalability, building performance improvements and sustainability pathways to continue and expand this innovative work.
Adaptable modular design and value-added manufacturing could provide scalable, cost-effective delivery of high-quality homes, helping meet local demand, reduce import dependency, attract private investment and contribute to job creation, economic resilience and net zero goals. Native renewable timbers further increase biodiversity with appropriate silvicultural management and contribute to climate change mitigation.
