The seven-storey complex at the Ronan Group's Spencer Place development, near Dublin's Docklands, will feature 325 residential apartments and a 102-key aparthotel.
The Spencer Place Development Company lodged revised plans for the development - which already has permission for 165 apartments. There are also proposals to build new streets and pedestrian walkways through the site, while all apartments would have balconies or terraces.
The plan, if it goes ahead, would be one of the biggest single-apartment developments in the city centre, and as it exists in a strategic development zone, a decision may be fast-tracked.
Ronan acquired the site from receivers appointed by nama for a reported €43 million in 2016.
