Galliford Try has been chosen for a £32m deal to build Northumberland County Council’s HQ in Ashington.
Construction News understands the firm beat Bowmer & Kirkland and McLaughlin & Harvey to the contract to deliver the five-storey Grade A office.
The project will also include upgrades to local roads, modifications of existing junctions and the provision of nearly 500 parking spaces.
Plans for the scheme were approved in July, after a consultation which found the council’s current Morpeth HQ would cost more than £12m to refurbish, including works to the roof, windows, lifts and electrics, which would still leave the building more expensive to run than a modern office.
Morpeth’s County Hall, which is only 30 years old, has not had any major refurbishment works over the past 10 years.
The same consultation found that the move to the new HQ could save up to £16m over 25 years, while bringing economic benefits of nearly £53m to Ashington.
The move to Ashington would also free up the County Hall site for redevelopment, which could provide up to £56m of economic benefits to Morpeth.
The council said it intended to redevelop the County Hall site into housing, although it will consider other options, including a mixed-use development comprising a commercial or leisure element.
The project is expected to start on site next month, with completion in 2019.
Northumberland County Council leader Grant Davey said: ”This is a welcome next step in our Market Towns Initiative to regenerate and improve Northumberland’s towns.
“We’re pleased the scheme has now appointed a team to start work and can now progress for the benefit of the town, the county and the wider region.”
