South Yorkshire Police are on target to move to new headquarters next year after completing purchase of the premises.
Nearly 300 staff will move to refurbished Carbrook House, the former Abbey National call centre at Attercliffe.
They are currently based in three separate buildings including the existing force headquarters at Snig Hill.
The £5m move, which has been funded largely by the sale of outdated properties, is due to take place early in the new year.
Chief Constable Meredydd Hughes said: “The force has needed a new headquarters for many years but we ensured that our operational buildings and frontline premises were a priority.
“Having delivered new district buildings, a forensics building, new vehicle fleet facilities and a new training centre for officers and staff, we are at the final stage of providing our hard-working headquarters staff with accommodation that is fit for purpose.”
The Snig Hill building will become a district headquarters for the city of Sheffield.
