A new action group is opposing development plans for the Irish Glass Bottle site in Dublin.
The government last week announced plans for 3,000 new homes on the Nama-controlled site.
But the Irish Glass Bottle Site Housing Action Group believes the land should be used for Local Authority housing.
The group has drawn up its own plan for the 10-hectare plot.
Annette Mooney says local people must be accommodated.
"Many, many families in Ringsend have their children sleeping on sofas, they're taking in their grandchildren, they're in very overcrowded situations," she said.
"So we're basically saying to the Government: 'No - we own this Nama site, and we want this site for Council houses".
