[2] The early "Sheffield Towne Hall" was replaced by a second building, which had been designed by William Renny in 1699 and opened in 1700.

That year the building was extensively renovated and extended to designs by William Flockton (1804–64) of Sheffield and his partner George Abbott.

[4] Flockton & Abbott added a new central clock tower over a new main entrance on Waingate, the materials of which came from the parts of the building which had been demolished.

[5] At the same time, the building was extended northwards by three bays, to provide a separate Judges' Entrance on Waingate ('an enriched pedimented doorcase with Ionic columns in antis, with urns on the cornice above it');[1] and the building's courtrooms were linked by underground passages to the neighbouring Sheffield Police Offices.

[10] A campaign group, The Friends of the Old Town Hall was formed in November 2014 with the aim of getting the building's owner G1 London Property to state its intention for its future use.
