The government is due to make its mind up next month on the redevelopment of Smithfield market in central London.
The Department for Culture, Media and Sport said the question of whether to list the market was being considered. A spokesperson said: “We are looking at all the options and a decision will be made soon, possibly by the beginning of next month.”
Heritage campaigners are opposed to proposals to build a 10-storey office building, designed by architect Kohn Pedersen Fox, on the west side of the meat market.
A coalition of SAVE Britain’s Heritage, the Victorian Society and the City Heritage Society has launched a campaign to scrap the plans.
KPF says its proposals, which are backed by the Corporation of London, would improve the surroundings of the listed buildings and make them stand out more.
