However, there is potential for an infinite range of layouts of the space. Public facilities will be inserted into the space beside the main building. The box office is accessible, when the building is in use from a small courtyard created immediately beside the pavement of Earlsfort Terrace. The entrance following the boundary wall leads to the rooflit double height foyer. Behind the box office is a reception area and there is also a cloakroom.
Stairs lead to a mezzanine area with a bar, a seating area and a gallery.
Back stage facilities are commensurate with the performance space. Behind the stage area, there is direct access for the delivery of musical instruments and a hydraulic lift suitable for a concert piano. On the first floor there are dressing rooms and a green room. There is also a lighting and sound room at the rear of the auditorium and a practice room. Work on this project is at an advanced stage and the National Concert Hall wishes to acknowledge the Office of Public Works, the Department of Arts, Heritage, Gaeltacht and the Islands and Dublin Corporation for their assistance and support for this project.
