The framework is valued at £2 billion. DTS will deliver offsite timber panelised system build for Category 2 housing over four years.

Working closely with 23 local authorities and housing associations nationally, DTS will design, manufacture and install timber frame wall panel building systems that meet build speed, fabric performance, building design and cost requirements. With a fabric-first approach that achieves net zero operational carbon, housing providers can use DTS’ timber systems to create sustainable, resilient, and affordable homes that meet the Future Homes Standard.

Earlier this year, DTS became one of the first manufacturers to achieve Buildoffsite Property Assurance Scheme Plus (BOPAS Plus) in recognition of the quality and durability of its offsite build systems. With DTS’ state-of-the-art open and closed panelised systems – Alpha, Delta or Sigma ll – works can still be carried out on site, ensuring that social value potential is reached within the communities served.

Mike Perry, business development director, Donaldson Timber Systems, said: “By securing a position on the OSHA MMC Cat 1 and Cat 2 Framework, we can build upon our strong relationship with affordable housing providers nationally and bring them along on DTS’ timber frame, fabric-first journey.

“We look forward to facilitating greater efficiency and value for clients who procure via this framework, and supporting OSHA’s mission to deliver 20,000 homes with MMC technology.”

Matthew Harrison, chief executive of OSHA member Great Places Housing Group, said: “We’re delighted to be working with Donaldson Timber Systems on the new OSHA framework. We’re confident they will be able to work with us and the OSHA clients in delivering the sector’s extensive development ambitions. We were pleased with the positive response from the market and received high quality proposals and substantial social value pledges for our communities. We are now looking forward to mobilising the framework and working together on new projects to realise our ambitions of delivering much-needed affordable homes.”
