James Hardie forecast highlights demand for flexibility but avoids delivery models.
The James Hardie Modern Homes Forecast 2026 sets out a view of how Australians are expected to live, but stops short of addressing how those homes are delivered. Smaller homes. Greater flexibility. Higher performance. Spaces that can adapt to changing household structures and economic pressure.
Taken at face value, these are design trends. Look closer, and they begin to read as delivery constraints.
Across the report, homes are described as adaptable, efficient and capable of supporting multiple functions at once. There is a strong emphasis on flexibility, durability and long-term performance.
These are not framed as optional. They are baseline expectations.
What remains largely unaddressed is how those expectations are met in practice. At the same time, the supply chain is starting to align with the conditions required to deliver it.
Design intent is moving toward system thinking
The report repeatedly returns to the idea that homes must “do more with less”, balancing cost pressures, environmental performance and changing patterns of occupancy.
In practical terms, this points to:
These are not purely architectural decisions. They align closely with how buildings are designed for manufacture and assembly.
A home that needs to adapt over time is more likely to rely on standardised grids, repeatable components and coordinated service zones. That is the logic of systems-based design and it underpins most offsite construction models.
Yet the report frames these shifts through façade treatments and interior outcomes. The delivery implications remain largely unspoken.
The productivity constraint sits underneath the gap
This disconnect reflects a deeper issue within the construction sector.
As Ray White economist Nerida Conisbee notes, construction has seen minimal productivity growth over the past three decades, with output per hour largely unchanged since the late 1980s. In contrast, most other sectors have recorded sustained gains.
The reasons are structural. Construction remains:
These characteristics make it difficult to embed and scale efficiency improvements.
Artificial intelligence is beginning to address some of these inefficiencies. Its impact is most immediate in reducing downtime between trades, identifying design clashes before construction begins, and improving decision-making through better forecasting. These are meaningful gains, but they operate within the existing delivery model. AI improves coordination, not structure, and does not change the site-based, sequential nature of construction.
Efficiency is being defined by performance not size
The Modern Homes Forecast signals a shift away from size as a measure of value. Efficiency, adaptability and durability are now positioned as defining characteristics of modern housing.
From a delivery perspective, this points toward:
The report acknowledges that demand for prefabricated, modular and mobile homes is growing at around 9.3% annually in Australia.
“This shift is not abstract—it’s driven by systemic pressures. Australia faced a shortfall of 46,000 dwellings in 2024, caused by rising costs, labour shortages and limited land supply. In response, homeowners and builders are embracing modular and prefabricated formats that enable faster delivery, lower costs and greater design flexibility.”
For a manufacturer operating at scale, that acknowledgement carries weight. James Hardie supplies into mainstream residential construction rather than edge-case innovation, and its forecasts tend to reflect where demand is consolidating. In that context, the inclusion of prefabrication reads less as a trend call and more as an indication of direction.
The report also places weight on multigenerational living and more complex occupancy patterns, with homes expected to support different users and uses over time.
At a single dwelling level, these can be resolved through bespoke design. At scale, they require repeatable systems. Offsite construction addresses this through modular configurations, platform-based design and interchangeable components. The outcome may appear customised, but the underlying system is consistent.
The largest productivity gains in construction are still expected to come from robotics and modern methods of construction, including prefabrication and modular building. By shifting activity into controlled factory environments, these approaches enable standardisation, automation and more consistent quality, addressing the structural limitations that have held productivity back.
A gap between narrative and delivery
The Modern Homes Forecast 2026 defines the pressures shaping housing demand and the attributes expected of future homes.
What it avoids is the structural shift required to deliver those outcomes at scale.
The characteristics it promotes align closely with offsite construction methodologies, while the productivity constraints identified across the sector point in the same direction.
The supply chain is starting to align with the conditions required to deliver it.
