The former Bromley Civic Campus site, which includes the Grade II listed Bromley Palace, has been acquired by Galliard Homes.
The sale of the site follows Bromley Council’s move to the new Civic Centre building at Churchill Court.
The council said the move will bring “financial savings”.
Bromley Palace Park, which contains the former Civic Centre grounds, will remain open to visitors.
The site is surrounded by green spaces, residential housing, and a four-storey car park, which was not included in the sale.
The sale of the site opens up the historic Civic Centre site for potential redevelopment, subject to planning permission.
This development could deliver new homes for Bromley and improve connectivity between the Civic Centre campus, the town centre, and nearby residential neighbourhoods.
Councillor Colin Smith, leader of Bromley Council, said: “Whilst it was very sad to leave our former home at Stockwell Close, the benefits and financial savings the move has already driven before it, ultimately made that decision a very easy one to make.
“We now wish Galliard Homes, the Old Civic Centre’s new owners, our very best wishes in bringing their new acquisition to market in the shortest time possible and I know that they will be keen to share their plans to understandably curious neighbours at the earliest possible opportunity.”
Simon Welch, director of land at Galliard Homes, said: “Bromley continues to be a sought-after location for both residents and investors, with a thriving town centre, excellent transport links, abundant green space, and highly regarded schools.
“We appreciate the importance of this site for the London Borough of Bromley and are excited to play a role in shaping Bromley’s future, supporting developments that build on the area’s appeal and create lasting benefits for the community.”
The successful completion of the sale of the former Civic Centre site for £13,501,000 followed confirmation in August 2024 that an unconditional offer had been accepted, with the council then also officially moving to Churchill Court, the council’s new Civic Centre home opposite Bromley South train station.
