A developer has lodged a fresh application for more than 650 apartments in Raheny.
Plans for the site beside St Anne's Park have long been subject to opposition from locals.
Last year, planning permission was granted for 536 houses and apartments at St Paul's College but it was challenged by locals in the High Court and later turned down by the planners.
It was claimed it was an over-development of the land and concerns were raised about the impact on Brent geese in the area.
The developer is continuing to fight the decision but has since lodged fresh plans for 657 apartments, in blocks up to 9 stories high, according to the Irish Times.
That's a 20 percent increase on the number of homes previously proposed.
