Renewed attempts to have a number of additional buildings in the Moore Street area declared as protected structures have been agreed by Dublin city councillors.
The buildings, which are numbers 10, 20, and 21 Moore St, O'Brien Mineral Waters and the remains of the White House - both on Henry Place - and the bottling stores on Moore Lane, were used by volunteers in 1916.
They were included in the High Court decision to extend National Monument protection from the four buildings at 14-17 Moore St to a wider "battlefield site".
However, this decision is being appealed by the Government.
They are part of a larger site owned by receivers for Chartered Land who had plans for a massive shopping centre development.
The entire site has since been purchased by the property company Hammersons.
Councillor John Lyons (PBP) said councillors had voted to include the five additional buildings two years ago.
City Planner John O'Hara said it had not been possible to gain permission for access from the owners to carry out the inspection necessary for them to be declared protected.
He said a protected designation would be premature until this can be carried out and that he would write to the chair of the Moore St Advisory Group with a view to getting access from the new owners.
However councillors agreed to again instruct council officials to initiate the process of having the buildings protected.
