Dublin city councillors last night voted to make the Oscar Traynor site development 100% social and affordable housing.
Back in November Councillors rejected a plan which would have seen developer Glenveagh Properties build 853 homes on the State-owned site and sell 50% of them privately.
A plan subsequently drawn up by a cross-party group of councillors to have the tenure mix 40% social, 40% cost/affordable rental and 20% affordable purchase was passed during the full council meeting.
Councillors from the Green Party, Labour, Sinn Féin, Social Democrats, People Before Profit and most Independents voted for the report setting out the tenure mix.
They also called on the Government to increase the site services fund from €50,000 to €100,000 per unit.
Fianna Fáil and Fine Gael councillors abstained from voting on the plan.
They said they wanted to see more affordable purchase homes but that they would not oppose the plan.
