Hundreds of Birmingham City Council staff will be moved out of more than 40 office buildings as part of a major rationalisation of the local authority's property portfolio.
The council is planning to save about £2 million by surrendering leases over the next five years.
Consultants are recommending a radical review of accommodation, with the intention of replacing 54 existing offices spread across the city with nine or ten administrative buildings.
An inquiry by Deloitte found 9,100 council staff currently occupy one million square feet of space.
The intention is to get rid of 250,000 square feet of offices, equivalent to a reduction of 1,600 desks.
Peter Jones, the council's assistant director of property and major projects, said: "The new portfolio will offer the council an administrative office estate that is modern and provides the working conditions now required and expected by staff.
"In the context of attracting and retaining quality staff resources this is highly important."
Mr Jones said that a number of the council's existing buildings were in a poor condition and coming to the end of their useful life.
Two-thirds of the employees in the exercise are involved in back-office functions and do not need to meet the public as part of their normal duties.
They will be re-located to offices around the edge of the city centre close to public transport nodes.
The retained portfolio will consist of: The Council House; 1 Lancaster Circus; Tamebridge House, Perry Barr; Orphanage Road, Erdington; New Aston House, Ladywood; Sutton New Road, Erdington; Lifford House, Stirchley.
The council cabinet committee for property is expected to back the proposed changes.
Committee chairman Paul Tilsley, the deputy leader of the council, refused to comment.
