More than 740 apartments in Dublin city centre have been granted planning permission.
The homes will be built in blocks of up to 23 storeys, in a development beside Connolly Station.
A hotel, offices and shops are also planned for Connolly Quarter, but permission for those is still pending.
Dublin Chamber has called the development "absolutely appropriate".
Graeme McQueen said it is a "perfect example of the kind of smart city planning that is badly needed in Dublin".
"Sites like this, positioned within the heart of the city and close to good public transport connections, are ripe for high density development".
