Two major housing developments that would have provided more than 650 new homes in Dublin and Wicklow have been refused planning permission under the fast-track process.
Applications to build 657 housing units in the north Dublin suburb of Donaghmede in and Enniskerry, Co Wicklow, were rejected by An Bord Pleanála on grounds of design and environmental concerns respectively.
The Donaghmede development, proposed by Belwall, would have provided 438 apartments and a childcare facility on a two-hectare site formerly owned by the Missionary Society of St Columban on the Hole in the Wall Road.
The project comprised four apartment blocks ranging from five to eight storeys.
However, An Bord Pleanála ruled that the plans did not provide adequate separation between the apartment blocks, which resulted in habitable rooms being overlooked by the balconies of other apartments.
The board said the layout of the scheme would "seriously injure the residential amenity for future occupiers of the units".
The development had been opposed by a number of local landowners and residents, as well as by the management company of the adjoining Grattan Wood apartment complex, who complained about the project's lack of community or social services such as schools.
In a separate ruling, An Bord Pleanála refused planning permission for the proposed development by Capami of 135 houses, 84 apartments and a childcare facility on lands at Kilgarron Hill, 1km from the centre of Enniskerry.
It is the second time in two years that the board rejected an application by Capami to build more than 200 units on the site as it could not be satisfied that the development and a proposed waste management facility would not adversely affect the nearby Knocksink Wood Special Area of Conservation.
It said there were deficiencies in the information provided by the developer in its Natura Impact Statement, particularly in relation to the lack of reference to protected oak woods.
Wicklow County Council claimed it would be out of keeping with the established pattern and character of development in Enniskerry.
