30 Second Briefing
AtkinsRéalis’s offsite arm EDAROTH has delivered 12 social and affordable homes for Raven Housing Trust in Epsom using a precision-engineered system with up to 65% of materials produced in a Bradford factory, above the UK government’s 55% offsite threshold. The units, manufactured across four sites and assembled onsite, are designed for net zero operational performance, to exceed emerging Future Homes Standards and to be independently assured for 100‑year-plus service life. EDAROTH positions the industrialised, digitally designed model as scalable, repeatable housing infrastructure aimed at de-risking programmes and attracting long-term investment.
Technical Brief
- Factory production in a controlled environment is used to cut material waste and on-site rework.
- Digital design is integrated with manufacturing, enabling coordinated tolerances and reducing interface clashes during assembly.
- AtkinsRéalis emphasises programme certainty, positioning the system to de-risk delivery for housing associations and councils.
- The model is framed as a template for scaling social and affordable housing output using modern methods of construction.
Our Take
AtkinsRéalis’s use of EDAROTH offsite housing in Epsom sits alongside its large UK public‑infrastructure roles such as the Sizewell C civil works framework, signalling that the company is trying to anchor itself across both mega‑projects and smaller, repeatable housing delivery models.
Delivering 65% factory‑produced materials versus the 55% government requirement suggests EDAROTH is positioning its system to stay compliant even if UK offsite thresholds tighten, which could give Raven Housing Trust and other social landlords more certainty on future regulatory alignment.
