Could Robotics and Timber Solve Britain’s Housing Shortage?
Gigantic robot arms guided by artificial intelligence are producing timber building frames at a factory in Oxfordshire, England, offering a potential solution to the UK’s housing challenges. With the government targeting 300,000 new homes per year, some housebuilders say combining technology with sustainable materials could address both skills shortages and environmental goals.
England remains behind many similar economies in the share of timber-framed homes, and Britain as a whole is one of the slowest adopters of construction robotics, according to Heriot-Watt University’s National Robotarium.
“We’re seeing more major and smaller housebuilders embracing timber to overcome skills and carbon challenges,” said Alex Goodfellow, CEO of Donaldson Timber Systems (DTS). The company produces timber-frame walls, floors, and roofs for homes and commercial buildings, delivering pre-assembled sections for rapid onsite assembly. Its automated production reduces labour needs, costs, and construction time by roughly 10 weeks compared with masonry, while a study by Rider Levett Bucknall found timber to be 2.8% cheaper than traditional materials.
DTS’s Witney factory uses AI to digitize designs, minimizing paper drawings, while robotics and laser technology streamline production for roughly 100 homes per week.
Barriers remain. Timber historically faced resistance in England due to concerns about durability, rot, and fire. Amit Patel of the Royal Institution of Chartered Surveyors noted difficulties in securing warranties for timber homes, while past efforts by Barratt Homes in the 1980s faltered over similar issues. Current building regulations and fire safety guidelines, however, have mitigated many of these concerns, according to Andrew Orriss of the Structural Timber Association (STA).
The STA estimates that off-site timber construction could deliver around a third of the government’s annual housing target. In 2023/24, England built nearly 200,000 new homes, with approximately 40,500 of those using timber frames. Builders including Vistry and Taylor Wimpey have opened or plan to open timber-frame factories, and Bellway intends to use timber for a third of its projects by 2030.
Timber’s environmental benefits are also highlighted. Simon Park, head of sustainability at Bellway, said timber stores more carbon than it emits, whereas concrete blocks are among the largest carbon contributors. Yet, around 80% of timber used in the UK is imported, primarily from Europe, compared with 20% of bricks. Mortgage availability for timber homes remains a concern but could improve with stronger government support, according to mortgage broker Riz Malik.
An ageing construction workforce underscores the need for robotics. About 20% of UK construction workers are over 50, with a quarter expected to retire in the next decade. Robotics adoption hubs, supported by £40 million ($54 million) from the government, aim to modernize the sector, though the UK lags Europe and the U.S. in construction robot density. In 2023, there were 0.5 robots per 10,000 UK construction workers, compared with 1.5 in Europe.
Frank O’Reilly, DTS manufacturing director, said robotics not only addresses labour shortages but also attracts younger, tech-savvy talent into the industry. “It encourages young people to consider this as a career,” he added.
