At least 60,000 new homes could be built on land already owned by the state.
The finding is contained in a new report from the Land Development Agency to be published this morning.
The LDA has identified land in Dublin, Cork, Limerick, Galway and Waterford that could provide for around 60 thousand new ‘affordable homes’.
Five regional centres are also recommended for development in Sligo, Letterkenny, Dundalk, Drogheda and Athlone.
However, it says there are still obstacles to unlocking state land for housing.
