The first municipal building in Carrick-on-Suir was a four-storey square tower in West Gate known as The Tholsel, which was completed in around 1500.

[4] It was designed by Thomas Anthony in the neoclassical style, built in brick with a cement render finish, and was completed in around 1844.

The central bay featured a short flight of steps leading up to a segmental headed doorway.

[7] The building became an important venue for public meetings: the Irish nationalist, Constance Markievicz, gave a talk about the Easter Rising to a packed audience in the town hall in November 1917.

[10] A major programme of refurbishment works, which involved the construction of a new glazed entrance façade, to the north of the existing structure, as well as a new three-storey extension behind it, was carried out by Tom O'Brien Construction at a cost of €2.4 million, to a design by Deaton Lysaght Architects, and completed in March 2019.
