Originally accommodating the Carrick-on-Suir Town Council until 2014, it now serves as a hub for Tipperary County Council, providing essential services to local residents. The town’s first municipal building was a four-storey tower known as The Tholsel, completed around 1500. This tower featured an octagonal roof lantern added around 1750 and a clock added in 1784.
The current structure was initially a mechanics’ institute, funded by public subscription and led by John Ponsonby, 4th Earl of Bessborough. Designed by Thomas Anthony in neoclassical style, this brick building, with a cement render finish, was completed around 1844. Its symmetrical five-bay frontage on New Street includes a segmental-headed doorway, round-headed ground floor windows, sash windows on the first floor, and full-height Doric columns and pilasters supporting a prominent entablature and central pediment.
In 1866, after the mid-19th-century appointment of town commissioners, the building was converted for their use. In 1899, it became the offices of the newly established urban district council. This site gained historical significance when Constance Markievicz, an Irish nationalist, addressed a packed audience about the Easter Rising in November 1917.
After limited refurbishments in the 1970s, the building continued as the urban district council’s office until 2002, later transitioning to the town council’s office until its dissolution in 2014, aligning with the Local Government Reform Act 2014.
A significant €2.4 million refurbishment, led by Tom O’Brien Construction and designed by Deaton Lysaght Architects, was completed in March 2019. This project added a new glazed entrance façade, a three-story extension, and a business hub, revitalising this historic site.
