STRUCTURAL ELEMENTS 65 TIMBER STEPS UP


Andrew Orriss of the Structural Timber Association (STA) outlines how timber construction off ers housebuilders a route to ‘carbon-conscious design’ allied to commercial effi ciency in the sector.


s housebuilders and architects work toward delivering on the UK’s net zero commitments and the pressing demand for more homes, timber construction is stepping forward as a practical, sustainable, and commercially viable solution.

The UK Government’s renewed support of the Timber in Construction (TiC) Policy Roadmap adds fresh momentum to the shift towards more sustainable construction with structural timber, providing the housebuilding sector with a structured pathway for adoption. However, beyond policy direction and climate targets, the success of timber in the built environment hinges on early design decisions, collaborative planning, and a skilled workforce ready to adapt.


The case for timber as a low-carbon material is well established. Structural timber systems offer a signifi cantly reduced embodied carbon footprint compared to conventional alternatives, maing them a natural fi t for environmentally responsible design. Yet, just as compelling are the commercial advantages timber provides to developers and contractors. Timber-framed homes can be constructed in nearly half the time of traditional masonry builds, often within 15 weeks, which enables earlier site turnover, improved cash fl ow, and better risk management. Quicker weather- tightness, often achieved six to 10 weeks earlier than with brick and block, further accelerates internal work and handovers.


With the pressures of meeting housing targets and controlling costs, these time savings are not just attractive, they are becoming essential. or timbers benefi ts to be fully realised, the design community must do more than simply swap one material for another. Timber demands a different design approach, one that embraces its properties and construction systems from the outset, and early collaboration is essential. Architects should engage with engineers, contractors, and clients at the concept stage to ensure design decisions support best practices in timber. Fire, durability, and acoustic performance requirements must be addressed through integrated planning rather than late-stage compliance checks.
