An application was lodged by Tipperary ETB and the Board of management of Scoil Ruain in Killenaule last March for additional facilities at the school.
The proposals are for a two-storey extension to the front of the existing school comprising a new school entrance foyer area at ground floor level.
This would include a Reception/Admin room, three meeting rooms and storage facilities.
The upper level which will be accessed via stairs or lift will comprise a two classroom ASD unit and five mainstream classrooms, with connections to the existing school building.
Internal alterations to the existing school building will include the provision of a new music room.
