Dublin City Council is calling in an architect and urban historian with a view to protecting 16 Moore Street, the last headquarters of the leaders of the Easter Rising in 1916.
Representatives of a group set up to ensure the preservation of the building talked about the property with deputy city manager Eoin Keegan on Friday in a meeting they described as "very helpful".
"The council has engaged a firm of architects and designers to do a survey of the property and to make recommendations to the council about the possible foundation of a museum there," according to conservationist Damian Cassidy.
"The building is of enormous historic significance as it was the last refuge of the 1916 leaders and is where the surrender document was drawn up. It is in a terrible state and in danger of further decline and vandalism," said Mr Cassidy.
A spokeswoman for Dublin City Council said that architect Grainne Shaffrey of Shaffrey Associates and urban historian John Montague had been commissioned to conduct a survey of the building. However, there is an issue over access to the property and its ownership is the subject of an ongoing dispute.
"There is an issue for us of how much of this building is actually original. A lot of that area in Dublin was pretty much demolished after 1916," said the council spokeswoman.
"We have to find out where exactly number 16 Moore Street actually was, for a start," she said, adding that bringing in Ms Shaffrey and Mr Montague was the first step towards possibly getting the building listed and thus protected. "We need to evaluate it to see if it's warranted."
Last week a campaign was launched by a group wanting to save the building, which has fallen into disrepair. The campaign has the support of An Taisce, as well as several politicians, relatives of those who fought in the Rising and conservationists.
The gathering was told of the significance of the building, as well as its dilapidated state. Although it is scheduled to be preserved in the city draft development plan, much of the roof has been lost over the last two years.
