Dublin City Council is to build 1,500 new homes on a 25-acre site in Cherry Orchard near Ballyfermot in West Dublin.
30% of the residential units will be affordable housing.
There will also be new civic plazas and open spaces and a new railway station which is being built in partnership with the developers of the nearby Park West development.
The City Council has shortlisted six tenders for the project and will make a final decision within the next month.
