[1] The design involved a symmetrical main frontage with nine bays facing onto Town Hall Square with the end bays slightly projected forward and decorated with Corinthian order pilasters; the central section of seven bays featured a single-storey tetrastyle portico with paired Ionic order columns supporting an entablature and a balustraded balcony; there was a round headed French door flanked by round headed windows on the first floor.

[1] Above the first floor windows were six roundels depicting key people in the town's history: King Edward III (who granted land to the town's freemen), Archbishop John Whitgift (who was born in the town), Gervase Holles, (who served as a local member of parliament during the English Civil War), Charles Pelham, 4th Earl of Yarborough (who served as High Steward of Great Grimsby), Queen Victoria and Prince Albert.

[9] The police cells, located in the basement, were subsequently converted to create a series of local history exhibits entitled the "Time Trap Museum".

[10] Queen Elizabeth II, accompanied by the Duke of Edinburgh, visited the town hall and met with civic leaders on 12 July 1977.

[15] Works of art in the town hall include a portrait by George Jennison of King Edward VII.
