The Taoiseach says there is a target of 17,000 social housing units to be delivered this year.
Enda Kenny says it is "not acceptable" to have people living in hotel rooms and B&B's as depicted in a TV programme last night.
He has come under fire from the opposition on leaders questions in the Dáil with accusations that he provided billions for banks but nothing for housing.
The Taoiseach says the coalition has put the 'money on the table' for social housing.
"In terms of direct bills, local authorities the chief executives and their staff have been given money targets and objectives and told to get on with it.
"We need to see the blocks and concrete and houses emerging from the 300 sites that are currently being developed at various stages all around the country.
"I'll send you the details Deputy Adams, for your information," the Taoiseach said.
Deputy Gerry Adams commented: “There are now over 5,100 citizens in homeless accommodation, including 1,638 children.
"No doubt some of those children will read the 1916 Proclamation in their class rooms during this centenary year. What will it mean to them? What does it mean to the Government?
“We know where the Government stands of course. They would rather cherish all the bankers than all of the children of the nation equally.
"They would rather US style tax cuts than help those in need of a home.
“An Taoiseach must step up and acknowledge that homelessness is a direct consequence of Government policy. The fact is they do not acknowledge homelessness as a priority and they have refused to build social and affordable homes.”
