Nick Boulton at the Trussed Rafter Association says that with calls for faster and better housing delivery continuing to shape the sector, making practical progress relies on involving specialists.
The demand to build more housing has been a long standing issue within the sector. With the Government targeting 1.5 million new homes, the industry faces familiar pressures such as a shortage of labour and the need to build more sustainably.
Price and availability of materials, together with stricter performance requirements, continue to influence project planning. Planning authorities are also placing greater emphasis on placemaking and consistency of character in new developments. Collectively, these pressures shape how projects are designed and delivered.
Trussed rafters play an important role in meeting housebuilding targets as the engineered timber designs produced by TRA members can help to deliver the consistency, predictable performance and reliable programme delivery that developers need.
The importance of roofscape design
Roofscapes are a visible part of any housing development. They influence streetscape quality and contribute to the identity of neighbourhoods while affecting how residents experience their homes.
Developers are increasingly acknowledging this by encouraging a thoughtful mix of pitches, height variations, and roof forms.
Roof structures can also affect the functional aspects of homes, such as daylighting, privacy, density, and the adaptability of internal layouts. Attic trusses, for example, allow room-in-roof options without increasing the building footprint.
Suppliers work to ensure roof concepts can be engineered efficiently and installed safely. Complex forms such as hips and valleys can be produced accurately when integrated early in the design process. This approach can help to avoid issues on site and ensure that design intent is delivered.
Scalable construction
A key benefit of trussed rafters is their suitability for efficient and high volume construction, as each truss is designed to exact specifications and produced under controlled factory conditions, resulting in consistent quality and reduced waste.
For large developments, predictable installation is important, and our members can provide components that support clear scheduling while reducing the risk of delays. Trussed rafters arrive on site ready to install, supporting shorter programmes and helping manage weather related challenges. In addition, small teams can install trussed rafters safely and quickly, which is particularly important given ongoing labour constraints across the sector. Engineered trussed rafters also meet the structural, acoustic, thermal, and fire-safety standards expected in modern housing. They integrate with various construction methods, including masonry, timber frame, and offsite approaches. Their adaptability means they are suitable for both volume housebuilding and more technically demanding projects.
Using certified timber
As the industry moves towards Net Zero, material choices play a role in reaching sustainability goals. Trussed rafters manufactured by our members are made from Programme for the Endorsement of Forest Certification (PEFC) and Forest Stewardship Council-certified (FSC) timber, which ensures responsible sourcing and traceability. This supports developers’ environmental reporting obligations while aligning with expectations for low-carbon construction.
Timber stores carbon during its lifetime and can reduce the embodied carbon of new homes. It is renewable, recyclable, and well-suited to circular economy principles. Its relatively low weight reduces transport emissions and simplifies handling on site.
Every member commits to responsible timber use and efficient manufacturing processes. The experience of the members reinforces confidence that environmental aims can be achieved without compromising structural performance or practicality.
Roofscape Design Awards
The TRA’s annual Roofscape Design Awards highlight how engineered roof structures support good design and practical delivery. The awards showcase projects that demonstrate balanced use of form, structure, and construction efficiency.
Recent award entries include a specialist healthcare facility delivered in partnership with a trussed rafter manufacturer, a heritage building conversion that preserved original roof character while upgrading performance, and a new roofscape design for a contemporary residential scheme integrating solar technologies within engineered timber structures.
Looking ahead
Delivering new homes at scale will require closer coordination across the supply chain. Early engagement between clients, designers, manufacturers and housebuilders can improve buildability and programme certainty.
Clearer planning expectations around roofscapes would improve project predictability and reduce risk. Continued investment in skills will also be important to ensure the workforce
can deliver engineered timber solutions with confidence.
The trussed rafter sector already has the technical capability, production capacity, and experience needed to support housing delivery. The opportunity is to use this expertise more strategically across design and construction workflows.
Thoughtful roofscape design strengthens placemaking and long-term performance, while certified timber supports lower carbon construction. As the UK moves forward with its housing goals, the sector’s experience will remain vital to achieving well designed, deliverable developments.
