A public meeting will take place tomorrow over the development of more than a thousand homes at O'Devaney Gardens in the inner city.
An attempt by independent city councillors to stop the increased height and density of the plan has been put on hold pending legal advice.
Almost all of the units will be made up of apartment blocks, up to 14 storeys high.
One of those raising concerns is Lorcan Sirr, Lecturer in Housing at TU Dublin;
"There's going to be I think four tower blocks way above the height limit that's allowed in Dublin...you're going to put two thousand people into a residential area which is ok but there's no consideration for any extra services that these people need."
An open-air public meeting will take place close to the site at midday tomorrow. It's being organised by the Stoneybatter-O'Devaney Action Group who plans to look for a Judicial Review of An Bord Pleanála's decision.
The group has described the development as "monstrous".
