Structural Timber Association intends to quadruple the market share of timber frames in new homes

 Wednesday, December 17, 2025

The landscape of English housebuilding is standing at a structural crossroads. While traditional masonry has long dominated the southern skyline, a coordinated effort led by the Structural Timber Association (STA) is gaining momentum to flip the script. The mission is unambiguous: double the market share of timber frame construction in England from its current 12% to 25% by the year 2030. This isn’t just a target for the sake of growth; it is a vital component of the UK’s broader decarbonisation strategy. With the Future Homes Standard coming into full effect in 2025, the pressure is on developers to deliver homes that are “zero-carbon ready.” Timber frame construction—a proven, scalable, and high-performance solution—is uniquely positioned to meet this challenge.

To overcome decades of “brick-and-block” tradition in England, the STA has moved beyond theoretical advocacy. In October 2025, the association launched the Timber Frame Learning Journey, an immersive, hands-on program designed to dismantle the barriers of perception.

The journey takes a diverse group of stakeholders—including important homebuilders, representatives from Homes England, lenders, and architects—across the border to Scotland. Why Scotland? Because the region serves as a living proof of concept, where over 92% of new homes are already constructed using timber frame systems.

Andrew Orriss, CEO of the STA, noted after the inaugural trip:

“Scotland is years ahead. This isn’t a plan; it’s happening now. We wanted developers to see for themselves that timber frame isn’t just a niche alternative—it’s the backbone of faster, greener housebuilding.”

The delegates witnessed the entire lifecycle of a timber home, visiting:

• Managed forests & sawmills: Observing the sustainable sourcing that ensures long-term timber security.
• Engineered timber factories: Seeing the precision of Category 2 panelised systems that reduce on-site waste by up to 90% compared to masonry.
• Live housing sites: Real-time evidence of how timber frames allow buildings to be made weather-tight in half the time of traditional builds.

Collaboration is the second pillar of the STA’s strategy. The newly formed Homebuilders Timber Frame Hub brings together the UK’s top 15 homebuilders to align their efforts. Currently, eight of these firms—responsible for nearly 78% of the group’s total output (approx. 78,000 homes annually)—are already investing in timber-led developments.

Early collaborative sessions identified 21 common hurdles preventing a total transition. Through intensive surveying, the Hub has prioritised the top three issues for immediate action in 2026:

1. Fire performance data: Providing standardised, evidence-based risk assessments.
2. Thermal detailing: Creating a digital platform to help architects master airtightness and U-values.
3. Change management: Supporting the workforce transition from traditional wet trades to dry, off-site assembly.

The STA isn’t stopping at site visits. A suite of digital tools and professional development projects is scheduled for release throughout 2026 to simplify the adoption process:

• ‘Where to Start’ Guide: A digital manual developed in partnership with Swedish Wood and Timber Development UK (TDUK).
• CPD Modules: Continuing Professional Development courses tailored specifically for housebuilding roles, from site managers to procurement officers.
• Thermal Detailing Platform: A centralized hub for technical drawings that ensure compliance with the 2025 Future Homes Standard.

While volumetric modular construction (Category 1 MMC) has faced recent high-profile setbacks and insolvency shocks, timber frame (Category 2) offers a middle ground of innovation without extreme risk. It uses established supply chains and familiar assembly methods, making it a “step-change” rather than a disruptive “leap” for most developers.

Richard Lankshear of the Future Homes Hub highlighted the synergy:

“We’re focused on sharing lessons from real projects that are already delivering all-electric, low-carbon homes at scale. Timber is the most effective way to meet these targets today.”

Crucial to this 2030 goal is the STA Assure program. This quality assurance scheme provides the necessary “gold standard” accreditation recognized by major warranty providers like NHBC, LABC Warranty, and Premier Guarantee. By mandating regular audits and installer training, the STA ensures that every frame built meets rigorous structural and safety legislation, giving lenders and insurers the confidence to back timber-led projects.

The STA’s strategy is a rare blend of ambition and pragmatism. By 2030, the goal is for one in every four new English homes to be timber-framed. With the 2026 project pipeline fully funded and major homebuilders already on board, the industry is moving past “why” and onto “how.” As the next Timber Frame Learning Journey prepares to depart in early 2026, the message is clear: the future of English housing is rooted in wood.
