The operators of one of Ireland's most storied pubs, O'Donoghue's, have become ensnared in a planning row with their next door neighbour, the French restaurant Marcel's on Merrion Row.
This follows O'Donoghue's appeal to An Bord Pleanala's decision made last month by Dublin City Council (DCC) to approve Marcel's plans to extend its dining area.
In the application, the operator of Marcel's, Central City Catering Ltd, has secured planning permission for a 30sq metre open-air terrace for dining on the first floor.
O'Donoghue's has hired planning consultants Brock McClure to outline the pub's opposition to the plan.
The objection states that O'Donoghue's "is extremely concerned about how this proposal could negatively impact on their business by means of causing damage to the visual amenity of the surrounding area, adding to noise and light pollution, particularly the adjoining properties".
The objection says the terrace development "would be inherently damaging to the character of the surrounding area".
It states the proposal will impact on O'Donoghue's "commercial operations and fails to take account of the existing immediate context".
O'Donoghue's previously fought off an earlier attempt for a terrace on the first floor by the same firm in August 2014.
That application also went before An Bord Pleanala and the appeals board ordered the omission of the terrace after its inspector found the first-floor terrace "would be unacceptable in terms of its visual impact on the streetscape".
However, in the DCC planning report giving the go-ahead to the current application, the planner pointed out the reasoning for the omission of the terrace was due to visual and residential amenity.
In years following this decision "circumstances in the locality have varied in terms of vibrancy and use".
The pub is owned and operated by the Barden family and last year profits at the pub more than doubled to €452,098.
A decision is due on the appeal in January.
