Furthermore, producing timber frame systems offsite improves reliability. Firstly, as they are produced in controlled factory environments, quality control is assured, resulting in fewer errors during assembly. Secondly, the fabrication of timber frame systems in a factory is not weather dependent, meaning build programmes become far more predictable.
UK homes to 3 million tonnes. Currently, the use of structural timber in new homes results in the sequestration of a little over 1 million tonnes of carbon per year. It is clear that increasing the use of structural timber systems within new housing developments would help the UK on its road to achieving net zero.
In addition to helping housebuilders meet their environmental targets, opting to use structural timber systems within new developments can help to alleviate other pressures. On average, using timber frame systems can reduce build time by eight weeks, when compared to traditional masonry methods. This is largely because timber frame is manufactured offsite, and delivered as prefabricated panels that can be erected quickly.
Understanding both the environmental and structural benefi ts that timber presents, the question is why are more housebuilders not taking advantage of it now? Ultimately, the answer to this relates to culture. In Scotland for example, 92% of new build homes use timber frame systems, due to a long-es- tablished and very successful heritage using this method. Whereas in England, which relies heavily on masonry-based techniques, only 9% of new build homes use timber frame.
Hence, for timber to become used more
widely, the fi rst hurdle will be overcoming the culture within housebuilding that focuses on ‘traditional methods’ as well as the hesitancy around alternative methods. A big part of this will be educating and raising awareness about the sustainable benefi ts of timber, its structural capabil- ities, and demonstrating that it is a perfectly safe building material. To support this, the STA continues to
Sustainable alternative for development
Marshalls Bricks & Masonry’s Mayfair Vintage facing bricks have been used by housebuilder Backhouse on its Merlin Rise development to achieve a high-quality, reclaimed brick aesthetic that also aligns with the sustainability goals of the business. Unlike clay bricks, concrete products do not require ring and as a result, only a small amount of
additional energy is used in the manufacturing process. Concrete bricks are net absorbers of CO2 due to their continuous carbonation over their lifetime. By selecting the Mayfair Vintage brick as an alternative to a traditional clay brick, Backhouse has saved 93 tonnes of carbon.

invest heavily in third party research to provide factual data and evidence regarding the use of timber as a structural building resource. In addition to this, STA Assure, the STA’s quality standards accreditation scheme developed to recognise excellence within the structural timber sector, ensures that certifi ed members meet or even exceed current legislation and regulatory requirements. While traditional building methods are aiming to be carbon neutral by 2050, timber offers the opportunity to achieve net zero now. Housebuilders that are looking to contribute towards net zero – as well as combatting the housing crisis – should look no further than the environmental and structural benefi ts offered by timber.

Standard solution solves threshold problems
The Type LTT Level Threshold Tray encapsulates threshold masonry exposed to damp transmittance from the exterior inwardly and from ground level upwardly. The LTT protects the top and both faces of the masonry whilst each end rises and wraps around the reveal faces – including into the cavity. Flooring, insulation,
membranes and DPC’s are able to converge with both skins that are safely isolated at the point of convergence. Packaged per opening, controlled cost, compliancy + consistency – every time. For more information, please visit the Cavity Trays website.
