Locals in Clontarf told Dublin City Council they would fight plans for a Family Hub for the homeless 'tooth and nail'.
A former guesthouse on St Lawrence's Road has been converted into an accommodation centre with cooking and laundry facilities, in a bid to take families out of hotels and B&Bs.
The parents and children were due to move into the Clontarf Hubin July.
However emails of opposition to the plans have been published in The Irish Times today.
One message from earlier this year revealed how locals believe it would be 'a new ghetto in our community... We are trying to get people to buy houses and move back to the area. This will turn that updside down.'
In a statement to 98FM News the Dublin Region Homeless Executive says it "does not wish to comment on this article apart from reiterating that our priority is the provision of quality temporary accommodation for families with children who are experiencing homelessness and who are currently accommodated in commercial hotels. Work is ongoing on the family hub facility on St. Lawrence’s Road in Clontarf and it is expected that the facility will be operational by the end of this month."
Meanwhile the head of Fingal County Council has said there won't be enough social housing coming on stream to tackle the crisis until well into next year.
While Social Justice Ireland says the government must build 90,000 social housing units or admit its housing policy has failed.
Director Dr Sean Healy has told 98FM "neither the scale of what the government is doing nor the structure of how it's doing it is really anywhere close to what is required to tackle the crisis. There are 90,000 households, not individuals, on waiting lists. Yet the government plan only provides half of that amount of social housing over the next five or six years."
It comes as the Housing Minister calls an emergency summit for this Friday with the heads of Dublin's four local authorities.
The meeting is being convened in the wake of three homeless deaths last week.
A former chef was found unconscious on Suffolk Street, while a Tallaght mum died by suicide in a Leixlip hotel.
