500 new homes, a creche and a sports centre are being planned by South Dublin County Council.
The site in Kilinarden, Tallaght, has an estimated capacity for 500 homes with the exact number to be decided through planning processes.
A proposed mix for the development includes 60% affordable homes, 20% social homes and 20% private homes together with a creche, a community building incorporating a sports pavilion and high-quality park.
The project is expected to be completed within four years from the granting of planning permission.
Councillor Ed O’Brien, Mayor of South Dublin County, said: “This development is a key part of this Council’s overall housing plans for the coming years and I very much welcome that we have advanced to the tender stage.
“Over the coming months, a number of projects will be announced of various types and tenure and this large - scale mix of social, affordable and private housing will kick start the Council’s overall plan for housing.
“Most importantly, it brings a step closer to the opportunity to house up to 500 families in our County and in an area that is in great need of these homes, this must be welcomed.”
