NOTTS County Council is to give up a customer-service base in Annesley as part of a bid to save £2.5 million a year.
Mercury House, at the Sherwood Business Park, is among 17 buildings the council will stop leasing or sell off in a bid to slash running costs.
The plan will see a total of 600 members of staff — including 50 from Mercury House on Little Oak Drive — relocated to either County Hall or Trent Bridge House in West Bridgford.
It will leave the council with just six buildings throughout the county.
Money raised by the sell-off of some of the properties will be ploughed into a £10 million to modernise both County Hall and Trent Bridge House in the coming four years.
Coun Reg Adair (Con), lead member for finance and property, said: “We are now embarking on a programme to make better use of a smaller number of office buildings to reduce costs and protect our frontline services.”
Mercury House is leased by the council at the business park, which is close to junction 27 of the M1.
