French giant Bouygues has snapped up £100 million turnover Hampshire contractor Warings for an undisclosed sum.
The firm said it had bought the Portsmouth-based builder as part of a long-term plan to boost its UK presence.
It is the first time that the French firm, which has until now carried out work in the UK mainly on PFI hospital and schools projects, has bought a general building contractor since it formed a UK division 10 years ago. Its previous acquisitions have been street lighting contractor David Webster, generators firm Icel and building services group Thermal Transfer.
Warings, which has nearly 250 employees, carries out new build and refurbishment projects across the south of England. These include residential, healthcare and commercial jobs plus industrial, airport and defence work.
Bouygues' UK arm employs 300 staff and is planning to double its current £100 million turnover within two years.
