Campaigners fear a heritage site in Birmingham will be destroyed if a planning application is given the go-ahead.
Christopher Wray, owner of the grade II-listed Christopher Wray building in Bartholomew Row, near Millennium Point, is seeking permission to demolish the site and adjacent properties.
National charity SAVE Britain’s Heritage has joined forces with the Victorian Society calling for the application to be refused.
Campaigners want to see the buildings returned to their former glory and put to better use.
Joe Holyoak, chairman of the Victorian Society, which has submitted a formal objection to the proposals, said: “It is black and white because as far as the application to demolish goes, this building is a properly listed grade II building for its historical and architectural interest and it should in no circumstances be demolished. It is both against local and national policy, there is no doubt.
“The reason is that it is so invaluable. The buildings are the microcosm of our city’s industrial history over the last 250 years – a priceless architectural documentation.
He added: “One of the significant factors that needs to be emphasised is that when the city centre park is constructed, the buildings will have a frontage onto the park.
“There is a fantastic future for them.”
The building dates back to the latter part of the 18th century when a terrace of Georgian houses was first built.
A malthouse was added in 1800 and, shortly after, a warehouse and shops were attached.
Christopher Wray, which designs and manufactures decorative lighting and furniture, moved into the premises, but the business closed some years ago.
Chairman Mr Wray now wants consent to demolish the buildings from number 7 to 12 Bartholomew Row but the application does not state further information about what he proposes to do with the site.
Tim Bridges, conservation adviser for the Victorian Society, said the site holds ‘tremendous historic importance’ as a record of the transition from house to industry and that evidence of the transgression was quite rare.
He said: “The building demonstrates a classic Birmingham story of a Georgian town house being adapted and extended for industrial use during the Victorian and Edwardian periods.
“Other commercial uses of different parts of the premises at that time reflect the diversity of small traders who once operated in thriving and tight-knit industrial communities.’’
Marcus Binney, president of SAVE said: “Old buildings like this stand for the hive of human activity and enterprise which made Birmingham the workshop of the world as opposed to a back street parking lot.”
Mr Wray was unavailable for comment.
