The firm said the decision had been taken to deliver a more efficient property portfolio in several English regions.

Among the properties understood to be facing closure are the Isle of Wight and Bristol offices.

It is understood some other smaller local offices are likely to be merged into regional centres with less than 50 job cuts expected.

A company statement said: “As part of our Build to Last transformation programme, we are proposing changes to our regional construction business to make it leaner, reducing our overheads while maintaining our ability to deliver projects to clients around the UK.

“We are proposing  the consolidation of a number of our delivery units and local offices in England, making more efficient use of our property portfolio.”
