Proposals for the derelict grade two-listed building will see it brought back to life as a community hub and wedding venue.
The mansion sits in Buile Hill Park but has been closed to the public for several years after falling into a state of disrepair.
Under the council’s plans to bring it back into community use, the building will be home to Salford’s registry office, which will move from the Civic Centre in Swinton into the first and second floors of the mansion.
Downstairs, a café will sit alongside community and heritage exhibition space and a function room. The first and second floors will feature community meeting rooms and a flexible space for meetings.
Buile Hill Park and Mansion featured in the BBC’s Manctopia series, during which it was the subject of a potential refurbishment project.
The scheme would have been delivered with the proceeds from a housing project developed by Capital&Centric on nearby brownfield land. However, the 60-home neighbourhood didn’t progress.
Under the latest plans for the estate, part of the land that Capital&Centric earmarked for houses will be used as a car park.
Salford City Council and the Buile Hill Mansion Association have worked together on the plans, which will go forward for planning permission early in the year.
If approved, work is expected to start on site later in 2022.
Salford City Mayor Paul Dennett said: “I made a commitment to bring Buile Hill Mansion back into sustainable use and I’m delighted that we can now reveal the plans to do just that.”
Buile Hill Mansion was built between 1825 and 1827 for Thomas Potter, the first elected Mayor of Manchester.
