No 16 Moore Street, where leaders of the 1916 Easter Rising had their last headquarters before surrendering to British forces, may yet avoid demolition if campaigners succeed in getting it listed.
Several Dublin City Councillors are expected to table a motion to retain the site and develop it as a public information and education centre at a city council meeting today.
They will also call on the City Manager, Mr John Fitzgerald, to fast-track getting it listed.
An Taisce is putting in an application to have the house listed as an early vernacular 18th-century building.
The site is currently the subject of High Court action and as a result the issue of ownership remains unresolved.
According to Dublin City Council, No 16 lies in the Carlton development site for O'Connell Street.
A Dublin city architect, Mr Jim Barrett, called the public concern "somewhat premature" and said the building was "not going to be knocked".
An Taisce's spokesman, Mr Ruadhan Mac Eoin, said :"There is a historical opportunity for Dublin City Council to make an enlightened decision here .
"Heritage is a non-renewable resource. Should the authorities demolish No 16 we would call it a crass act of vandalism and would say it represented cultural cleansing for the sake of commercial gain," he added.
A walk from 16 Moore Street to Dublin City Hall prior to the meeting is also being planned by Sinn Féin councillor Mr Larry O'Toole to highlight public concern and to commemorate the anniversary of the execution of James Connolly on May 12th, 1916.
