[1] The design involved an asymmetrical main frontage facing southeast towards the corner of Kerr Street and Mark Street; the left-hand section featured a curved wall with five segmentally headed windows with voussoirs on the ground floor, five round headed windows with voussoirs on the first floor and a conical roof above.

The right-hand section was narrow and blind, while the side elevations of the building were fenestrated in a similar style but featured stepped gables and finials.

[4][5] A war memorial, which was designed by Frank Ransom in the form of a bronze statue of victory mounted on a pedestal and which was intended to commemorate the lives of local service personnel who had died in the First World War, was unveiled in front of the town hall in the presence of Lady Macnaghten of Dundarave House on 11 November 1922.

[11] An extensive programme of restoration works costing £1.6 million, managed by Hearth Historic Buildings Trust, financed by the Heritage Lottery Fund and carried out by McCloskey & O'Kane of Limavady to a design by Consarc, was completed in 2005.

[14] The building then resumed its role as an events venue and the comedian, Shane Todd, presented an episode of the BBC New Comedy Award programme in the town hall in November 2021.
