The Cabinet has signed off on a plan for so-called "posh prefabs" to ease the housing crisis.
One hundred and fifty of the "modular" housing units will be ordered immediately to ease the problems over Christmas.
The housing and homelessness crisis was raised in the Dáil in leaders' questions today, and will be discussed again this evening.
Taoiseach Enda Kenny told Sinn Féin's Mary Lou McDonald that he was impressed with the quality of the units that will be ordered.
He said: "They're very acceptable and guaranteed for insulation, warmth and comfort, and for families to not be in bed and breakfasts and hotel rooms."
The Simon Community recently said there were 707 families trapped in emergency accommodation right now, among them almost 1,500 children.
