A home that did not exist a month ago is now standing in Revesby.

That is the headline from Green Timber Technology’s Homes NSW project, where the Orange-based advanced manufacturer is currently delivering 32 new social homes across 16 Western Sydney sites as part of the NSW Government’s $6.6 billion Building Homes for NSW program. The project is one of the most visible live tests of what offsite manufacturing can actually do at delivery pace.

Four homes have already been fully installed. The rest are progressing across Western Sydney, with GTT on track to hand over keys in a timeframe that traditional construction methods would struggle to match.

What the project actually involves

The Western Sydney contract is structured as a $24 million Design and Construct agreement with Homes NSW. It covers 14 duplexes and two dual-living homes, delivering 32 architecturally designed four-bedroom residences across the region.

GTT’s approach removes the conventional site-by-site construction model. Wall, floor and roof panels are precision-manufactured at the company’s factory in Orange, then transported to Western Sydney sites for rapid installation. Large structural sections are lifted into place in a single operation. The home that did not exist a month ago was not built from the ground up on site. It was manufactured in controlled conditions, then assembled.

GTT CEO Pete Morrison described the approach as removing uncertainty from construction rather than replacing the people in it.

“We are taking the uncertainty out of construction by manufacturing wall, floor and roof systems in a controlled factory environment, then installing them onsite with speed and precision. This is not about replacing the construction industry. It is about enabling an industry under pressure, giving builders and project partners a faster, more precise way to deliver homes when they are needed most.” — Pete Morrison, CEO, GTT

The system GTT uses is what the company calls a Kit-of-Parts model. Structural and manufacturing elements are standardised across all 16 sites, while layout, facade treatment and site response retain flexibility. That standardisation is what makes simultaneous delivery across multiple locations operationally viable.

Why the multi-site model matters

Running 16 sites in parallel is not something most builders attempt. The coordination demands across trades, certifiers, logistics and program management are significant.

The offsite model changes the equation. When critical structural components are manufactured to consistent tolerances in a factory, the on-site phase is compressed. Weather delays, trade availability and supply chain variability all affect site-based construction differently than they affect a manufacturing floor operating to a production schedule.

For Homes NSW, this matters because the program is designed to deliver at scale. The $6.6 billion Building Homes for NSW program aims to deliver up to 8,400 new social homes over four years across metropolitan and regional NSW. Individual projects are not the story. Volume and pace across the whole program are.

Ian Harris, Project Manager at Homes NSW, pointed to the broader significance of how the project was being delivered. “Western Sydney is a priority growth area,” he said, “and projects like this demonstrate how modern construction methods can support faster delivery of high-quality social housing while maintaining strong design and livability standards.”

The manufacturing base behind the homes

GTT operates from the nation’s largest state-of-the-art automated timber prefabricated manufacturing facility in Orange, founded in 2021. The facility uses CNC automation, digital design workflows and Design for Manufacture and Assembly principles to produce structural systems at consistent tolerances, with production capacity to deliver up to 1,000 homes per year.

Homes delivered under the program are expected to reduce the carbon footprint of a typical dwelling by more than 60 per cent, with structural timber sourced from regenerative plantation forests and factory processes designed to reduce material waste. Airtight building envelopes are also intended to lower heating and cooling costs for tenants over time.

GTT received a $4.8 million NSW Government grant in February 2026 supporting the growth of its advanced timber manufacturing capability. The funding is expected to generate more than 50 local manufacturing roles, with eight full-time employees already engaged including two carpentry apprentices focused on digitally enabled construction processes.

The company was named Western NSW Business of the Year in May 2026, with Morrison also receiving the Outstanding Young Business Leader award at the same event.

What this means for builders

Not every builder will move into offsite manufacturing. But the growth of programs like this has practical implications for builders working in the social housing space and in Western Sydney more broadly.

Large-scale government housing programs delivered through modern methods of construction create a different kind of site work. Civil preparation, connections, finishing trades and surrounding infrastructure all still require skilled on-site labour. Builders with established regional presence and relationships are well positioned to participate in those scopes.

There is also a supply chain dimension. GTT sources its structural timber through partnerships with locally based suppliers, with the Orange facility positioned to take advantage of shorter supply routes from NSW’s central forestry hub. Builders and suppliers entering government housing pipelines will encounter these procurement structures with increasing frequency.

The broader point is that the gap between what offsite manufacturing promises and what it can demonstrably deliver is closing. Every home installed under the Homes NSW program adds to a growing body of real delivery data. That data is what the industry, lenders and certifiers have been waiting for.

The regulatory environment is also moving in the same direction. NSW has introduced legislation that formally recognises prefabricated buildings in law and integrates offsite construction into the state’s approvals pathway, the kind of framework that has historically made MMC harder to finance and certify.

For builders not currently working in this space, the question is not whether offsite manufacturing is coming. It is what role traditional builders play alongside it. Civil works, connections, finishing and site management are all still in demand. GTT’s partnership with White Picket Fence to halve home build times used the same Kit-of-Parts system in a private residential context. The Homes NSW program is a different scale and a different client, but the underlying manufacturing model is the same. If the delivery milestones hold, it becomes one of the more compelling case studies in the national MMC conversation.

The Revesby site visit this week puts a visible face on what is otherwise a manufacturing and logistics operation running quietly across Western Sydney. The real measure of the project is not the day a minister walks through a completed home. It is the delivery data across all 32 addresses when the program reaches completion.
