A landmark development set to accommodate more than 1,600 civil servants is rapidly transforming the Darlington skyline, with construction of the new Darlington Economic Campus (DEC) headquarters progressing on schedule.
The five-storey Brunswick Street office, being delivered by the Government Property Agency (GPA), is expected to be completed in 2028 and will serve as the permanent home of the DEC. The facility will bring together staff from nine government departments, including HM Treasury, in a purpose-built workspace designed to support the Government's ongoing commitment to relocating key functions outside London.
During a site visit with contractor Kier, Tees Valley Mayor Ben Houchen welcomed the significant progress being made on the project.
Mayor Ben Houchen said: “It’s fantastic to see the new Darlington Economic Campus taking shape.
“Bringing the Treasury to Darlington five years ago proved our region could successfully host major national institutions – and it has shown we have led the way in establishing Government departments outside of London.
“More than 1,000 civil servants are already based here, and this new campus will build on that success by bringing together nine government departments in one purpose-built facility.
“This is an investment not just in a building, but in the future of Darlington and our wider region. It’s creating good-quality jobs, supporting local businesses through construction and reinforcing Darlington’s reputation as a place where major organisations choose to invest and grow.”

Established in 2021, the Darlington Economic Campus has become a major centre for government operations in the North East. It currently hosts staff from HM Treasury, the Department for Business and Trade, the Office for National Statistics, the Department for Culture, Media and Sport, the Ministry of Housing, Communities and Local Government, the Department for Energy Security and Net Zero, and the Competition and Markets Authority. The Department for Education has also maintained a long-standing presence in the town.
Construction milestones reached so far include the installation of more than 305 piles, completion of all foundation works and the commencement of structural steel frame installation. Roofing work is expected to begin in October, with the building's precast façade due to start taking shape in November.
The project represents a significant investment in Darlington’s economic future and is expected to strengthen the town’s growing status as a major centre for government, professional services and business growth.
Momentum around the campus extends beyond the Brunswick Street development. Earlier this year, Darlington Borough Council and development partner Cityheart announced plans to accelerate wider regeneration efforts linked to the expansion of the economic campus.
The partnership aims to create a new commercial quarter designed to attract professional services firms and businesses seeking to locate close to government departments. Plans also include the delivery of a sustainable town centre neighbourhood alongside a state-of-the-art STEM Centre of Excellence at Central Park, developed in partnership with Darlington College.
As work continues, the Darlington Economic Campus is increasingly being viewed as a flagship example of government decentralisation, helping to drive economic growth, create skilled employment opportunities and attract further investment into the Tees Valley region.
