The chief planning officer for Birmingham has called for the West Midlands Fire Service headquarters at Lancaster Circus to be given special legal protection to prevent its possible demolition.
Emrys Jones wants the 70-year-old landmark structure to be registered as a listed building.
Mr Jones's move follows the disclosure by The Birmingham Post that the Fire Authority is attempting to sell the site for £3 million and move out of the city centre.
Fire chiefs want the Government to grant the building a five-year immunity from being listed - a decision that would allow new owners to demolish the existing structure. It is feared that listed status would drastically reduce the sale value of the building, which is expensive to maintain.
The city council planning committee will decide this Wednesday whether to press for the fire headquarters's listing.
Mr Jones said: "The quality of the materials used is high, the steel-framed building is faced with handmade local bricks and Portland stone.
"The clock tower on Lancaster Place and the elevation to Corporation Street are of particular note, important elevations intended to make an architectural statement and express the building's civic status and purpose and which largely survive intact."
