An attempt by some Dublin city councillors to overturn the O'Devaney Gardens deal was defeated at a monthly meeting.
A motion supported by Sinn Féin , People Before Profit and some independents attempted to rescind a council report on the issue.
But councillors from Fianna Fáil, Green Party, Labour Party, members of the Social Democrats along with Fine Gael voted against and it was defeated by 35 votes to 22.
A motion to rescind would have to be supported by at least 35 councillors.
The original plan was to get developer Bartra to build 824 housing units with 50% private, 30% social and 20% affordable.
However, when councillors objected to prices quoted for affordable housing, an agreement was reached between the developer, council management and the parties controlling the council - the Green Party, Fianna Fáil, Labour and Social Democrats - to make 30% affordable rental and reduce the amount of private housing to 20%.
Minister for Housing Eoghan Murphy has raised concerns about this deal and pointed out that no funding source has been agreed.
Sinn Féin, who had backed the original 50% private deal, has since called for council to take over the project and make it all public housing.
However, DCC Chief Executive Owen Keegan told the meeting that the department will not fund the council to develop it adding "that's not my choice, it's just the reality".
