Sean Mulryan's Ballymore has entered a consultation with An Bord Pleanála for a new housing development in Dublin 11.
The high-profile developer is looking to build 478 apartments, including nine 'live/work' units on the Ratoath Road.
Due to the scale of the development, it will go through the planning board's 'fast-track' system, which was introduced by Housing Minister Eoghan Murphy in 2017.
Elsewhere, one of the country's largest homebuilders, Glenveagh, has been refused permission to build 174 apartments on Hearse Road in Donabate.
The developer had previously received permission on the site to build 35 houses and 62 apartments, but unsuccessfully tried to change the entire development to apartments.
In its decision, An Bord Pleanála made reference to the development's proposed "campus-style" design, insisting that it did not portray satisfactory urban design for the site.
The planning board also criticised the "dominance" of car parking.
