There are calls for ten thousand social housing flats in the city to be knocked down.
A new report from Dublin City Council shows three quarters of the city's stock are more than 50 years old and would take decades to refurbish.
According to the Irish Times, the council want to build taller, higher-density housing on the same land. The report suggests that the move could potentially triple the number of flats to more than 30,000.
Almost 20,000 families and individuals are on the local authority's housing list.
Earlier this month, the poor condition of a number of council flats was the subject of a ruling from the European Committee of Social Rights. They found local authority tenants in 20 estates in Dublin, Cork and Limerick were in breach of their human rights because of a failure to provide adequate housing.
