An appeal has been brought to An Bord Pleanála against plans for 43 houses in Ballyconnell.
A resident has raised health-and-safety fears about the proposed development.
Earlier this month, Cavan County Council gave Ballyconnell Properties conditional planning permission for 43 houses at Mullaghduff.
It would involve the demolition of a derelict dwelling to facilitate the residential scheme.
But Deirdre O’Reilly, of Amberwood Court, Ballyconnell, has appealed against the decision to the planning board.
In her submission to the council, she claimed the area would become a concrete jungle.
Ms O’Reilly also says the area is a health-and-safety risk to residents because of too many houses, too much traffic and too many cars passing.
She also claims the noise is horrendous, with the area already ‘overpopulated’ and ‘overpolluted’.
She also alleges that as a resident, she has been attacked and threatened in her home by people who have moved into the area.
An Bord Pleanála in due to make a decision on the application in four months’ time.
