A site comprising 43 hectares in Finglas, north Dublin is to be rezoned - paving the way for the development of hundreds of new homes.
Dublin City Council has voted in favour of rezoning land to "mixed use" which could see 2,200 homes built along with retail and business on the grounds in north Dublin.
The plan to develop the site was backed by a coalition of companies that own part of the plot.
The proposal to rezone the land was passed despite opposition from some local councillors
Fianna Fáil Councillor Keith Connolly said he was voting against it because he believed not enough research has been carried out.
He wanted a vote on a rezoning decision "this big" to wait because the National Development Plan for the city from 2022 until 2028 will be decided over the next few months.
Noeleen Reilly, an independent councillor in the area, voted yes, saying there is a housing crisis and there would be ad hoc development on the site if it was not rezoned.
