After significant population growth, largely associated with its development as a residential suburb of Dublin, the township of Blackrock appointed town commissioners in 1863.

The central bay, which was slightly projected forward, featured a round headed opening flanked by pairs of Ionic order pilasters supporting a cornice.

[9] The library, at the centre of the extended frontage, was slightly projected forward and was more elaborate than the town hall, with an ornate open pediment above the front door, full-height pilasters flanking each of the bays, panels containing swags above the first floor windows, and a long balustraded parapet at roof level, broken by a round-headed pediment above the central bay.

[15] By the early 1970s, the town hall was becoming dilapidated:[16] it served as the home of Dublin City Ballet and the Irish National College of Dance from 1982 to 1988.

[18] The works, which cost €9.5 million, were carried out by Collen Construction to a design by architects, McCollough Mulvin,[19][20][21] and the completed building was handed over by the Tánaiste, Eamon Gilmore, in May 2014.
