Gas and electricity supplier Opus Energy is consolidating its three existing offices in Northampton to create a single 90,000 sq ft headquarters.
It is currently refurbishing and extending John Dryden House, with completion expected in December. The company will then transfer its staff from its offices at Westbury Court, Moulton Park; Francis Crick House, Moulton Park and Regent Pavillion, Royal Pavillions.
It bought John Dryden House from Northamptonshire County Council. It was advised on the deal by Lambert Smith Hampton, which advises the company.
Opus Energy, which also has offices in Cardiff and Oxford, was bought out by power station company Drax Group for £340m in December 2016.
The move will see the energy supplier more than double its existing capacity to accommodate its 850-plus staff, with further space for growth.
