A final decision on proposals to transform derelict land into new energy efficient offices for Northamptonshire County Council on Tuesday.
If the plans get given permission at the meeting of the cabinet then building work could start within three months.
The plans could save millions of pounds of taxpayers’ money by moving out of its existing ageing stock of 12 HQ buildings, which cost £56,000 a week to run, into one purpose-built building in Northampton.
Councillors are being asked at the meeting to agree the final business case and, following a rigorous procurement process, agree to appoint design and build contractor Galliford Try to start construction of the new building following the completion of negotiations.
The business case forecasts the sales of those properties the council owns would raise more than £13 million.
