Avoca has been given permission to retain a change of use from creche to café at its Monkstown outlet in the face of opposition from a group of locals.
An Bord Plenala has given the plan to go-ahead after concluding that the proposed development "would not injure the viability and mix of uses in the area and would not lead to an over-concentration of café/restaurant uses in the area".
Last year, Dun Laoghaire Rathdown County Council gave the project the green light.
However, this was put on hold after the Longford Terrace Residents Association lodged a planning appeal with the appeals board.
The association told the appeals board that Monkstown already suffers problems associated with considerable traffic hazard as a result of inadequate parking provision.
They claimed that the development for which retention permission was being sought could result in a permanent and negative impact on architectural heritage.
The residents also requested the board to refuse permission until the impacts of the entire operation can be fully assessed and existing impacts due to noise, odour, visual intrusion and traffic, visual intrusion and traffic are addressed.
However, the board has given Avoca the green light to retain their operation after board inspector, Siobhan Carroll concluded that the proposal "would not unduly impact on the residential amenity of the appellants’ neighbouring properties and other neighbouring properties".
The appeals board also ruled that the proposal would be acceptable in terms of traffic safety and convenience.
Consultants for Avoca told the appeals board that the development of the Avoca Courtyard Café plays a key role in adding to the vitality and vibrancy of Monkstown Crescent.
The consultants said that the use is appropriate for the designated neighbourhood centre and complies fully with planning policy.
The consultants stated that "the continued use of the premises as a café will ensure the proper planning and sustainable development of the area".
