residents in Finglas have said they will take a legal challenge over plans for 40 modular units for homeless families as they fear their neighbourhood will become a "ghetto".
Around 100 people gathered yesterday at a rally in Finglas village organised by the Finglas Action Group.
Sandra Devlin, one of the organisers, addressed the crowd and outlined concerns about developments that residents feel will lead to an over-saturation of social housing.
She told the crowd they had consulted a barrister who believed there was a case for a breach of constitutional rights relating to the plans to build 40 modular units for homeless families at St Helena's Drive.
The group is opposed to a number of other social housing projects planned for Finglas.
Ms Devlin said the location where the modular units were to be built is known to have an anti-social behaviour problem.
There was also a problem with a lack of school places and other services.
"We will block the sites if we need to. We don't want to do it, we have to do it," said Ms Devlin. "We need to insist on proper planning on every site in Finglas."
The group fears the modular homes plans will cause the area to become a "ghetto".
They held up signs yesterday calling for "integration, not segregation" of housing in the area.
Former Labour councillor John Redmond said the community would welcome homeless families with "open arms", but added that Finglas should only take its "fair share" of social housing units.
"We don't want 100pc social houses," he said. "You need social and affordable houses. We need these people to be integrated into our community and more affluent areas of the city should be taking their fair share.
"There is a solution - we don't want modular homes, full stop, we want proper bricked homes that people can get a mortgage on and proper social housing.
"It's a quick-fix solution for a long-term problem in Finglas."
A spokesman for Dublin City Council (DCC) said the modular sites were approved by the local authority.
"It is our objective to acquire a mix of housing types across all five administrative areas of the city, endeavouring to meet demand," he said.
DCC also said there are proposals to produce a new plan for further upgrades to the village.
