Plans to abandon Trafford Town Hall as part of a scheme to reinvigorate the Old Trafford cricket ground have outraged a heritage charity.
The town hall was built in 1933
Lancashire County Cricket Club has decided not to quit the ground and instead redevelop the site and the neighbouring town hall.
Trafford Council would then move to a new venue near the Trafford Centre.
The 20th Century Society has called for the town hall - built in 1933 - to be preserved as a listed building.
Coun David Acton, leader of the Labour opposition group, said once residents understood the plan's implications opposition was likely to grow.
"When people realise this quite historic building - which has lots of character - is likely to be demolished or sold off, people may have a different picture," he said.
Coun Acton also claimed the town hall's new site would not be as convenient for residents to enter.
Cordula Zeidler, case worker for The 20th Century Society, said it would be applying to get listed building status for the town hall.
"We think it is a very important building, with a very interesting staircase and beautiful stained glass windows."
She said the town hall was one of several built in the early 20th century by Bradshaw, Gass and Hope and urged the council to rethink its proposals.
Council leader Susan Williams (Cons) said the town hall's 1980s annexe greatly reduced its heritage appeal and the new site would have easier public access as it is near the Trafford Centre.
She said buckets were in place some parts of the town hall because of roof leaks and added: "The feedback from our staff is that they are delighted to be moving."
