Construction group Galliford Try has secured contracts worth £77m to build two new office buildings in the UK.
The company will build Northamptonshire County Council's (NCC) new headquarters in Northampton for £38m and an office building for offshore engineering firm Subsea 7 in Surrey for £39m.
The four-storey Northampton headquarters will be built on an area of 17,600m² and will consolidate with the council's current offices in the town.
The headquarters, designed by BDP, was approved by the council's planning committee in May of this year, and will feature a café and landscaping around the site.
NBC councillor leader Jim Harker previously said: "This building is essential for us as an organisation as it will allow us to make £54m worth of savings by moving out of a current stock of 12 expensive-to-run, ageing HQ buildings in Northampton into one purpose-built, energy-efficient, low-carbon building."
Meanwhile, Subsea 7's office building at Sutton in Surrey will feature 150,000ft² of category-A office space and associated facilities.
Galliford Try executive chairman Greg Fitzgerald said: "We are delighted that Northamptonshire County Council and Subsea 7 have entrusted us with such significant projects.
"We have a strong reputation in the office sector and we look forward to providing these two clients with the first-class facilities they require."
