Gaelscoil Ballymun is a 12 classroom primary school located within a modest residential setting in North City Dublin. The fibre cement clad General Purpose Hall at first floor level has a striking presence on the street corner and cantilevers over the public thoroughfare below.

Brickwork elevations are designed to give a robust, yet attractive exterior to the school. The linear building footprint is orientated on an east-west axis to maximise the solar gain within the teaching spaces and offers privacy to the external play areas to the south.
