Plans have reportedly been submitted to build over 150 social houses on three sites in Dublin.
They include Dominic Street in the city, Belcamp near Darndale and Sackville Avenue beside Croke Park.
Meanwhile the Irish Council For Social Housing says the issue must be prioritised if we're to tackle the homeless crisis.
Spokesperson Karen Murphy says, "For too long social housing has been treated in a sort of stop/start way and we believe that it needs to be an accepted public policy priority, in the same way as education and health are."
The call comes as The Father Peter Trust appeals to the government to fast-track plans to use flatpack homes as a temporary solution to the housing crisis.
