Adderstone Civils is delivering the complete civil engineering infrastructure package for a major new residential development in Spennymoor, County Durham of around 248 new homes. The scope covers adoptable roads, foul and surface water drainage, utilities infrastructure, plotworks and associated external works, marking a significant milestone in the company’s growth and reinforcing its position as one of the North East’s emerging civil engineering contractors.

Works commenced in May 2026 and will run for approximately three years, with Adderstone Civils working collaboratively alongside Strata Homes to deliver the infrastructure required for the new community.

Key Areas of Delivery:

  • Roads & Plotworks
    Construction of adoptable roads, plotworks and associated external works across the development, forming the foundation for around  new homes.
  • Drainage & Utilities
    Installation of foul and surface water drainage alongside SUDS, drainage connections, utilities infrastructure- all engineered to support the development from the ground up.
  • Sustainable Earthworks Strategy
    Rather than removing excavated material from site, Adderstone Civils reprocessed approximately 22,000 cubic metres of excavated stone into a graded Type 1 sub-base specification, reusing it throughout the development. The approach has reprocessed and reused approximately 48,000 tonnes of construction material on site, eliminated the need to import virgin quarried aggregate, prevented an estimated 2,000 HGV movements, reduced embodied carbon by approximately 480 tonnes of CO₂e, and achieved zero excavation waste sent to landfill.
  • Local Employment & Supply Chain
    The contract has created 12 new permanent jobs, including six apprenticeships, with 100% of the project’s supply chain expenditure sourced within a 25-mile radius of the site.

The project reflects Adderstone Civils’ approach to modern civil engineering: retaining and reusing site-won material, minimising environmental impact, and investing directly in the local economy through jobs, apprenticeships and regional supply chains.

The contract continues Adderstone Civils’ expansion across the residential infrastructure sector, building on a growing portfolio of roads, sewers, drainage, earthworks and external works projects delivered throughout the North of England.
