Hundreds of blocks of flats in the city could lose their protected status to allow them to be demolished.
Dublin City Council wants to redevelop over 1000complexes like those on Mercer Street (near Stephen's Green) and Chancery House (near the Four Courts) which were built in the 30s.
Many were designed by London-born architect Herbert Simms, an architect credited with rebuilding Dublin in the early years of independence.

His buildings are protected structures because they're strong examples of 20th century architecture.
However in modern times they present problems relating to mould, damp, inaccessibility and fire safety standards.
It's more economically viable to demolish them than to refurbish, and in the context of the housing crisis, the City Council wants to de-list certain complexes to allow them to be razed and rebuilt.

But Associate Professor at the School of History and Geography in DCU, Dr Ruth McManus, wants as many to be saved as possible through retrofitting and refurbishment.
She says many are actually beautiful structures that may be gone by the time we've come to appreciate them.
"They're also important in terms of telling us something about our social history. The Simms blocks were part of a huge push to provide housing for the citizens of Dublin when people were still living in appalling conditions in tenement flats."
The report on the regeneration of Dublin City Council's flat complexes is to be discussed at the Housing Commitee's strategic policy meeting this Thursday.
