That is according to HOK, the global architecture and engineering firm leading the design for the three-storey, 57,000-square-foot building and an adjacent 350-bed forensic psychiatric hospital, both under construction on a campus being redeveloped as a centre of excellence for behavioural healthcare.

The administration building combines regionally sourced glulam columns and beams with cross-laminated timber decking — a structural approach rarely attempted in healthcare construction, where steel and concrete have long been the default.

Working alongside structural engineer KPFF Consulting Engineers to develop concealed proprietary connections and fasteners, HOK kept the exposed timber interior free of visible hardware…with several columns made from trees felled on-site.

Wood Central understands that the building is targeting LEED Gold certification and net-zero-energy readiness. Rooftop and site-mounted photovoltaic panels will generate on-site renewable energy, while advanced mechanical, electrical, and plumbing systems — including thermal storage — are designed to reduce peak energy loads. Fritted-glass curtainwalls bring daylight into the building’s core and offer occupants views across the surrounding campus.

The ground floor includes training and gathering spaces open to the wider community — a conscious step away from the closed, institutional character that has defined state psychiatric facilities for generations. It comes as the broader $947 million Western State redevelopment — the largest capital project in Washington state history — pushes toward a 2028 opening. The forensic hospital is scheduled to begin receiving patients later that year.

That is according to Pulse Tasmania, which reports the rig is designed to replicate the planned venue’s fixed-roof structure and will assess whether a treated version of the stadium’s ETFE roof material can eliminate the shadow problem that has dogged the project since early 2025.

Shadows have plagued the design from the beginning.

Last year, Wood Central reported that Cricket Australia and Cricket Tasmania wrote to the Tasmanian government demanding architects redesign or remove the roof entirely, saying the fixed-dome design made the venue “unlikely to be conducive to hosting Test matches” — and potentially unworkable for one-day and T20 fixtures too.

At the time, Anne Beach, the CEO of the Macquarie Point Development Corporation, told a parliamentary inquiry that the transparent covering created contrast on clear days — and that the timber and steel beams, engineered as small as possible, would still cast shadows.

However, in November, a Gold Coast company identified a potential fix: Cricket Tasmania CEO Dom Baker proposed a matte treatment that, when applied to one side of the ETFE material, would disperse light rather than pass straight through —  killing the sharp contrasts on the pitch.

Until this week, it had never been physically tested. Now, the rig will run assessments on shadow intensity, ball visibility, and playing conditions. It will also capture data on how roof treatments affect turf growth beneath — a secondary concern for groundskeepers at an indoor venue.

It comes after both houses of the Tasmanian Parliament approved the $1.13 billion project in December — the Upper House voting 9–5 after two days of debate. The 23,000-seat venue will be the permanent home of the Tasmania Devils AFL team. Its fixed dome, framed in Tasmanian-sourced glulam, would be the largest timber roof on any stadium in the world.

What the roof actually looks like

Late last year, Wood Central reported that the current design documents detail a hybrid timber roof lined with Tasmanian-sourced glulam, paired with metal deck cladding, steel rod bracing, and translucent ETFE pillows. The clearspan structure carries an internal clearance of 49 metres — enough headroom for Test-level cricket as well as AFL, soccer, and rugby.

The Macquarie Point Summary Report specifies lightweight ETFE pillows, a 20-millimetre timber laminate, a secondary glulam system, and Aramax metal deck cladding, all supported by steel rod bracing. The timber form is designed to reduce perceived bulk from street level and preserve harbour sightlines — a tough ask for a structure sitting on the edge of Hobart’s CBD.

That is according to Steve Walker, Principal of Terrafolia Advisory, who spoke exclusively to Wood Central after visiting a series of LVL manufacturing clusters in Linyi, Suqian and Guigang last week. And the production pivot, he says, is only part of the story. “What stands out most,” Walker said, “is the ability to produce high-quality structural products using young plantation logs.”

Part of that competitive edge is feedstock flexibility.

According to Walker, the mills draw on a wide species mix — domestic pine (Pinus massoniana), planted eucalyptus, New Zealand radiata and European spruce — with end customers specifying wood blends, quality grades and certification requirements before a board is cut. As a result, manufacturers can produce LVL on demand, at scale, to any dimensions worldwide.

It comes after Wood Central revealed that Chinese LVL arriving at Australian ports has surged 63 per cent in the ten months to October 2025, with new ABS data recording more than 205,000 cubic metres traded in that period alone. For Walker, the use of younger fibre, purpose-built infrastructure, and on-spec production means China can land product at costs that locals can only dream of.

For global forest asset managers, Walker says this represents a real opportunity.

The implication, he says, is simple: rotation length, fibre specification and market strategy are now directly linked. “Investors who focus on productivity optimisation and value creation, and who align forest resources with the growing demand for engineered wood, will be well positioned for the next phase of the industry,” Walker said. “The future of forestry will belong to portfolios that understand how fibre, manufacturing and markets are changing together.”

It comes as Walker last month set out the detailed case for how Australia’s plantation estate could be better deployed to meet exactly this kind of demand. His paper, A National Pathway for High-Productivity Forestry and Renewable Carbon Supply, published by the Rozette Institute, argues that Australia could double its plantation output without planting a single additional tree — through smarter rotation management, fibre alignment and productivity optimisation across existing estates.

Automated Architecture, or AUAR, makes portable micro-factories that produce the full wooden framing of a house — walls, floors and roofs — in 24 hours. Co-founder Mollie Claypool told CNN the system produces timber panels more quickly, more cheaply, and more precisely than a conventional framing crew, freeing carpenters to focus on construction rather than component manufacturing.

It’s a claim the building and construction supply chain wants to stress-test — but the underlying model is sound.

Architects send building plans to AUAR’s AI-powered software, the Master Builder, which calculates how many panels are needed and exactly how much timber a developer needs to purchase.

The micro-factory — which fits inside a standard shipping container — is dispatched directly to the building site with an operator, who uses a robotic arm to measure, cut, and nail timber into panels, leaving precise openings for windows, doors, wiring, and plumbing. Contractors fit the panels by hand.

One micro-factory, Claypool says, can produce the framing for a typical house in about a day — a process she says would take a conventional timber-framing crew four weeks. On cost, AUAR claims its service runs 30% cheaper than a standard framing crew and up to 15% cheaper than ordering prefabricated panels from a large off-site factory and transporting them to the site.

The system can build parts for buildings up to seven storeys high.

AUAR can also respond to timber’s natural variations. It accounts for knots, bends, and warps — calculating the most efficient cutting pattern from available stock to reduce waste. “The precision of the finished panels produces a tighter building envelope,” Claypool adds, “lowering heat loss and improving the energy efficiency of the finished home.”

AUAR currently operates three micro-factories across the US and EU, with five more scheduled for delivery this year. So far, it has raised £7.7 million, with 600,000 square metres of panels in production — enough to build hundreds of homes. But Claypool’s ambition is to grow that to 1,000 micro-factories on sites by 2030, producing 200,000 homes every year.

Wood Central understands the company is in active discussions with several new US partners as part of what it describes as a growth phase, following its 2024 partnership with construction investment firm Rival Holdings. That makes sense, given 94 per cent of single-family homes built in 2024 were timber-framed, and Goldman Sachs has identified the country’s housing shortfall — estimated at between 1.5 and 5.5 million homes — as the root of its affordability crisis.

None of this is happening in a vacuum. As Wood Central reported in December, Europe’s most advanced robotic prefab plants are already showing what zero-labour panel production looks like at scale — floor and wall assemblies delivered flat-pack to site with, as Timber Development Association CEO Andrew Dunn put it after touring those facilities, “not a single Allen key in sight.”

The question is whether those models can be adapted to local conditions, supply chains and building standards — and how quickly.

That urgency is reflected in where research dollars are flowing. Australian Forest & Wood Innovations (AFWI) — a $200 million research and development fund backed by $100 million in federal funding by the Australian government — has already committed to projects targeting exactly this gap, including the Automated Design for Prefabrication in Timber Construction and The Precinct, a large-scale centre to process wood fibre into frames, trusses, wall panels and flooring at manufacturing scale.

Back in the UK, David Philp — chair of the Chartered Institute of Building’s digital and innovation advisory panel, and not involved with AUAR — told CNN the window for treating this technology as optional had closed.

“These innovations were an opportunity a few years ago, but now they’re a necessity. They’re not a nice-to-have anymore — they’re key to any construction business model.”

But the remaining barriers are not technical, he said. It’s cultural — particularly in England, where just 9% of homes built in 2019 were timber-framed, compared to 92% in Scotland. “The technology and standards are there — the real barrier is culture. We’ve got deeply ingrained traditional ways of working, so the challenge now is people and change, not tools and processes.”

AUAR is not alone. London-based Facit Technologies produces on-site micro-factories for wooden components, while US-based Cuby Technologies uses modular production units that combine to handle various construction elements. What distinguishes AUAR’s portable, container-delivered model is its flexibility — particularly relevant for regional and remote sites where logistics costs make centralised prefabrication plants impractical.

As for the broader picture, Claypool isn’t shy about what’s at stake. “Good homes are not just a construction problem,” she told CNN. “It’s a social problem. When homes are scarce, and we’re slow to build them, everything else suffers.”

Slated to open later this year, the $1.45 billion, 39-storey ‘plyscraper’ will eventually contain more than 30,000 cubic metres of timber — shipped by European giants Stora Enso and Wiehag — across 21 storeys of the tower, with seven four-storey’ timber habitats’ sandwiched between steel-and-concrete mega floor plates above a seven-storey concrete podium.

And the glass panels going up are anything but conventional.

Spanish BIPV manufacturer Onyx Solar — working through Australian building products supplier Metz — is installing 1,794 crystalline silicon solar louvres across the tower’s active facade as part of a bespoke 247 kWp system. Speaking to PV Magazine Australia earlier this month, Onyx Solar revealed that each unit carries 28 mono-crystalline cells in a 4+4 mm glass configuration and produces 138 Wp at peak output. “The louvres also form a self-shading system that cuts direct solar heat gain internally,” Onya Solar said, turning the tower’s skin into a “vertical power source.”

Designed by BVN and New York-based SHoP, each ‘habitat’ comprises four floors of timbered space stacked inside a steel exoskeleton, eliminating the need for internal columns. “The timber floors are connected to the concrete floors via drag straps,” said Tim Allen, timber structural lead for TTW, who spoke at Timber Construct — Australia’s only timber construction conference — in late 2024. “Why build a 39-storey building partly out of timber?” Allen said. “Because it comes down to using the right timber for the right application.”

Whilst in October last year, Peter Morley, the Dexus project director overseeing the build, said the team had “broken the back on the most technical, structural phase of the project,” with the hybrid timber approach allowing the developers “to bring the building up quicker and get the façade on quicker than a more traditional build.”

“That’s because we’re jumping up five levels every time, and while we’re going up, we’re coming back and infilling with the timber within each of those five-storey zones,” Morley said. Atlassian Central is co-owned by Dexus and Atlassian, with Built and Japanese construction giant Obayashi appointed as builders, confirming the building remains “on schedule” for a 2026 opening, with the tech giant expected to take over five of the seven habitats in late 2028 following a full fit-out.

At street level, crews are also well advanced on a new pedestrian connection from Railway Colonnade Drive to the Devonshire Street Tunnel entrance — the heritage passage running beneath Central Station between Lee Street and Devonshire Street — which will, for the first time, allow pedestrians to access the tunnel directly from the colonnade as part of Central’s broader Third Square redevelopment.

“Unfortunately, there’s not much you can do apart from deal with asbestos when you find it to ensure that you’re providing a safe workplace and a safe building going forward,” according to Victorian Treasurer Jaclyn Symes, who spoke to ABC Melbourne Radio, who confirmed that the bill sits with the government and not the Australian Grand Prix Corporation under its contract with F1 rights holder Liberty Media.

Last month, Wood Central reported that the new building will include a striking timber waffle roof design — joining a growing roster of F1 facilities swapping steel and concrete for hybrid cross-laminated timber systems. Renders produced by Woods Bagot show a massive roof that will eventually shelter 14 F1 team garages.

“What excites us most about this design is how it elevates both elite motorsport and grassroots community sport under one roof,” said Woods Bagot Director Bruno Mendes, the project’s design lead. “We’ve engineered a facility that doesn’t just host one of the world’s premier racing events — it actively gives back to the local sporting community every day of the year.”

Inside the canopy, race control suites, media workrooms and administration offices sit alongside the garages, with expansive hospitality terraces framed by CLT beams and full-height glazing offering circuit and lake views for 5,000 Paddock Club guests. When Grand Prix teams pack up each year, the complex converts into a community sporting hub with seven indoor courts and clubrooms for local football, netball and basketball clubs.

Delivered by a consortium of AECOM, Icon and Woods Bagot, the redevelopment draws on the same team behind the award-winning T3 Collingwood — Melbourne’s tallest hybrid timber office building, also built by Icon.

Drawing record attendance, the Treasurer was happy to spruik the benefits of hosting the race: “I can point to the fact that the Grand Prix is a major economic contributor to the state and I know that many people are going to get along to that race this weekend,” she said. “It fills beds in hotels and people going out for dinner, and it keeps everyone busy, and it supports thousands of jobs.”

As for the existing building, constructed in 1995, Wood Central understands that full demolition is slated to begin days after Sunday’s race, with the new facility scheduled for completion ahead of the 2028 Grand Prix.

When International Paper closed its mills in Liberty and Chatham counties last year, regional demand fell by 3 million tonnes, and nearly 1,655 jobs disappeared seemingly overnight. Pulpwood that fetched US$15–16 a tonne before the closures now sells for US$5–6. As a result, demand, as of January, is down 60 per cent.

As a result, the economics have turned against landowners.

The average pulpwood price before International Paper’s exit was US$1,125 per acre. Last month it was US$375. “It costs about $350 to get an acre replanted,” according to Shane Harrelson, owner of Ohoopee Land and Timber in Vidalia, who spoke to local media over the weekend. “So to timber land owners, it doesn’t seem to make sense anymore.”

It’s that kind of mathematics that brought Georgia’s timber leaders to a summit in Midway  — looking for markets that paper and pulp can no longer provide.

Al Williams, state representative and Liberty County Development Authority Chair, said debt is pushing some to bankruptcy. “It’s devastating. If you own $2 million worth of equipment and you’re not hauling any logs… That’s scary.”

Joe Hopkins, CEO of Toledo Manufacturing and a landowner, was blunt. “We’re barely breaking even.” Whilst Steve Strickland, vice president of Beach Timber Inc. and owner of two pole mills, watched raw material supply evaporate.

“If you have 1,000 trees in that stand of timber, about 10% of that is going to be straight enough to make poles out of,” he said. “The other 900 trees that aren’t being harvested don’t have a mill anymore, so nothing is being cut.” A third mill he owns sits closed. “With the market in such bad shape, we have no current plans to bring it back online without major capital investment.”

Harrelson — whose business sold only 5% of its wood to International Paper — was nearly sunk by the paper giant’s collapse anyway. His company was shifting a maximum of 30 loads in the first two weeks after the closure.  “A year ago, I was selling 90 to 100 loads a week,” he said. “(But) if we were to sell under 40 loads a week for four to six weeks, we wouldn’t be able to keep going.”

But instead of despairing, Harrelson pivoted, harvesting mixed tracts of soft pine and hardwood across different species to reach different product markets. “It got him me back to 60 to 65 loads a week,” he said.

The December summit became as much a therapy session for embattled business owners as a venue for solutions. House Majority Leader Jon Burns, one of Georgia’s largest timber farmers, focused on the enormous opportunities in sustainable aviation fuel (SAF) with local producers responding to new European mandates to progressively lift SAF content in aviation blends.

A Model T that’s been running for 90 years vs a brand-new F-250.

However, Burns was candid about many of the obstacles. Europe blocks chemically treated wood from American mills, he said, and the unstable tariff situation makes US wood uncompetitive. “SAF also competes against cooking oil and municipal waste for feedstock — Georgia doesn’t own this market outright.”

“We can support our existing businesses,” Georgia Forestry Commission executive director Tim Lowrimore told state lawmakers. “But we also have the capacity to do more. To get where we want to be, you, as state leaders, have to be committed.”

Mass timber was another idea that gained traction. According to Byrnn Grant, CEO of LCDA, it’s more eco-friendly than steel or concrete, and far more durable than particleboard. Whilst Patrick Shay, architect from Gunn Meyerhoff Shay Architects, told the room that timber-based floor slabs can remove the need for a concrete pour, cutting time and cost.

“Georgia is uniquely positioned,” Marshall Thomas, president of F&W Forestry Services, recently told a state Senate study committee. “We can add jobs and tax base and position Georgia as a leader in the transition to a green economy.”

Amongst the roadblocks is the age of machinery and its equivalent. Seven of Georgia’s eight remaining pulp mills were built before 1961. “Brazil, China, and Indonesia are building brand new, state-of-the-art mills, and we’re running mills built in 1936,” one figure said.

“It’s a Model T that’s been running for 90 years vs to a brand-new Ford F-250.”

That is according to the latest ABARES Agricultural Commodities Report, published yesterday, which revealed that the gross value of forestry (GVP) production is expected to reach $2.23 billion in 2026-27 — a 3 per cent nominal increase or a 1 per cent real increase. And over the medium term, the GVP is projected to drop back $2.1 billion, with no material growth expected until at least 2030-31.

By the numbers, total gross value production in forests has dropped by 36 per cent over the past eight years — from about $3.4 billion in 2017-18 — with softwood relatively steady at about $1.5 billion, hardwood plantations flatlining at $0.5 billion and native forest continuing what is now a 20-year decline.

According to Diana Hallam, CEO of the Australian Forest Products Association, whilst the topline figures point to the vital role of sustainable forestry in producing essential products, the report also identified serious challenges and headwinds for the sector.

“Some of these challenges and risks include high manufacturing and energy costs, greater use of structural steel in residential and mid-rise construction, as well as a growing amount of imported timber products of varying quality flooding the Australian marketplace, including from China,” she said.

Hallam said the new estimates also reaffirmed the importance of aligning the government’s policy with Australia’s Timber Fibre Strategy, which outlines opportunities for the industry to make a greater contribution to national goals in carbon, innovation, and housing construction.

Softwood up, hardwood down, native at historic lows

The value of softwood plantation production is forecast to increase slightly in 2026-27, driven by short-term movements in detached housing demand. But ABARES warns that a gradual shift toward higher-density dwellings is expected to temper timber demand over the medium term, whilst projected increases in softwood log availability will ease unit prices.

Hardwood plantation production, however, is heading the other way.

And that’s because ongoing shifts in global paper markets are placing downward pressure on woodchip demand, whilst Vietnam’s growing share of global trade — combined with projected exchange rate changes — is continuing to erode Australia’s competitiveness overseas. ABARES expects Australian hardwood woodchip exports to settle at similar volumes but lower unit prices, with Australia holding a smaller, more specialised role in the market.

And then there is native forestry, where production has now fallen to historically low levels following 20 years of contraction driven by the transfer of multiple-use public native forests to nature conservation reserves and increased harvest restrictions.

A $570 million downward revision

ABARES has slashed its forestry forecast by more than $570 million — a 21 per cent revision from its December report — with exports the major driver of the writedown, down more than $619 million amid weaker production and prices.

It comes days after this masthead reported on a new white paper from the Rozetta Institute arguing that Australia needs a national roadmap to boost forest productivity and encourage new capital into the market.

On Friday, Wood Central spoke to the white paper’s lead author, Steve Walker, Principal of Terrafolia Advisory, and co-author Dr Lyndall Bull, who revealed that Australian plantations produce just 15 to 18 cubic metres per hectare per year against international benchmarks of 30 to 50.

And on Monday, Walker went further, telling Wood Central the sector’s decades-long focus on cost discipline had come at the expense of genuine value creation. “Lifting productivity on the land already planted is the fastest and most scalable opportunity,” Walker said. “International benchmarks in Brazil, India, Vietnam and China demonstrate that 30 to 50 cubic metres per hectare per year is achievable using proven technologies already available.”

“If we can do this, we can ultimately strengthen our capacity to produce more competitive engineered wood products like LVL and other EWPs,” he said, adding that the downstream benefits could add tens of millions of dollars to regional communities.

Led by George H. Berghorn, Modular Mass Timber for Housing Construction, a new research published in the Mass Timber Construction Journal set out to model the critical success factors behind Modular Mass Timber (MMT) adoption in US housing projects.

The team conducted a systematic literature review and semi-structured interviews with industry experts, identifying 15 factors — 7 from published research and 8 from practitioners. Before then, put the lot through Total Interpretive Structural Modelling and MICMAC analysis to determine which factors drive the system and which depend on everything else falling into place.

The findings are blunt.

Sustainability and logistics sit at the top of the hierarchy as the dominant drivers. Time, quality and efficiency sit at the base –  foundational, but only activated when the upstream factors are functioning. In short: get your supply chain and carbon story right, or the factory floor advantages of modular mass timber never reach the building site.

“The research aims to identify, evaluate, and model the Critical Success Factors that influence MMT adoption in housing projects in the United States,” according to George H. Berghorn, Kaustubh Thakare and MG Matt Syalthe, who said the findings “offer practical insights to facilitate scalable, cost-effective, and environmentally sustainable housing solutions.”

According to Mass Timber Construction Journal, the research “maps the real drivers behind adoption, not the hype,” and that housing “needs speed, cost control, and carbon discipline” — all of which modular mass timber can deliver, “but only if the industry treats adoption as a system problem, not a product swap.”

Wood Central understands that the research also delivers a strategic implementation guide aimed at developers, designers, manufacturers, and policymakers—a framework for deciding where to allocate effort and capital first. It’s the kind of applied output the sector has been short on whilst the conference circuit continues to celebrate landmark buildings.

Now, Australian Sustainable Hardwoods (ASH) — the country’s largest hardwood processor — says a $600,000 AFWI-funded research project is helping the industry find its way forward, with new species, new engineered products and new performance data that could change how timber windows are specified in Australia.

Daniel Wright, ASH’s National Business Development Manager, told Wood Central that window manufacturers are a big part of the company’s supply chain — from commodity and painted windows through to high-end architectural manufacturers — mostly across south-eastern states, but with a growing presence in northern New South Wales.

And Wright said the fallout from the decision to cease harvesting in Victorian forests has been immediate. “The window manufacturers of south-east Australia have been forced into a lot of change with the cessation of native timber in Victoria — just like we have,” he said. “But they also have upcoming changes to the NCC, which will structurally change how many of them operate.”

“Of course, what impacts our supply chain also impacts us.”

That disruption created confusion. “We’ve recently seen imported plantation timbers in the window market that don’t meet the specs they are intended for,” Wright said. “This was a direct result of Victoria’s hardwood being suddenly ceased. The window makers were trying to do the right thing, but were forced to make quick decisions.”

As one of the major stakeholders in the AFWI–AGWA Modernising Timber Windows project, led jointly by the Timber Development Association and the Australian Glass and Window Association, Australian Sustainable Hardwoods is providing timber species for testing their performance in modern systems.

“When we were asked to be involved, we saw this project as an opportunity to work together and help the window makers collectively find pathways forward that not only suit their specific needs, but also comply with upcoming changes to the NCC,” Wright said.

The project is also a chance for ASH to advance one of its newer species — Plantation Oak — as the company rebuilds markets lost when Victorian ash was taken away. Made from Shining Gum logs grown in a plantation for pulp, Plantation Oak is upgraded by ASH into higher-end, longer-term applications. Wright said a small part of every log can be used for architectural applications, but the majority needs to be engineered to get the best out of it.

“We’ve had success with Plantation Oak in MASSLAM, but in order to use this fibre in other market segments, we need to help build the standards and examples that everyone can follow with confidence,” he said. ASH is one of 10 timber suppliers involved in the project, alongside the Pentarch Group and others.

Now, the testing programme is about to shift up a gear.

Speaking to Wood Central today, Kylan Low — the Structural Engineer at the Timber Development Association leading the project — said next week’s round will put four configurations through their paces: a double-hung window, an awning and casement window, an awning and double casement window, and a centre bifold door. Low said the configurations are designed to capture various hardware setups used across the industry and will be tested under combined air and water pressure for durations representing storm periods.

In January, Low told Wood Central that the industry had been craving this kind of data for a very long time: “Window data hasn’t kept up with changes in codes, glazing, and timber supply.”

The project has also given a platform to the next generation. Jesse Ross — a Graduate Engineer at AGWA who has been working alongside Low since the project’s inception — recently shared his reflections on what has become his first major engineering project. Ross said that, unlike uPVC and aluminium systems, there was no prime operator in the timber window sector, meaning the entire system had to be built from the ground up.

Early testing revealed that some Australian hardwoods, such as Spotted Gum and Blackbutt, could outperform European staples. But given the project’s focus on species substitution, the team chose to work with the lowest passing species it could find. Designs have settled on 55/58 mm sash profiles with 24 mm glazing pockets, accommodating modern insulated glass units and manufacturable by small-scale workshops.

Ross said the industry engagement phase — travelling to state forums, meeting joiners, hardware suppliers and timber providers — was one of the most eye-opening parts of the experience. He found some joineries still working with outdated designs that didn’t fully comply with AS 2047 or accommodate drained insulated glass units.

“I learned that innovation is not just about creating new ideas,” Ross wrote, “but also about making them accessible to your audience.” The documentation phase — technical manuals, substitution procedures, shop drawings — is now underway, aiming to give any Australian joinery everything it needs to start building with confidence.”

The Modernising Timber Windows project is one of 30 research initiatives funded through AFWI — a $200-million-plus institute backed by $100 million in Commonwealth funding. It is generating new structural and performance data across a range of solid and engineered wood products, testing how timbers perform under AS 2047, Australia’s mandatory standard for windows and external glazed doors.
