[1] The building was commissioned to replace the ageing mid-19th century vestry hall on Upper Street which had been used by the Parish of St Mary's, Islington.

[3] The new building was designed by Edward Charles Philip Monson in the neoclassical style and built in three stages: first the rear wing facing Richmond Grove in 1922, second the northern part in Upper Street in 1925 and third the assembly hall in 1929.

[4] The design for the northern section involved a symmetrical main frontage with three bays facing onto Upper Street; it featured a stone porch with the borough coat of arms above flanked by full-height windows and Corinthian order pilasters to either side; there was also a window in a similar style on the first floor above the doorway.

[5] The principal rooms were the mayor's parlour, which was in the rear wing facing Richmond Grove, and the council chamber, which was in the northern part in Upper Street.

[10] The town hall hosted a high-profile reception, attended by the Duchess of Cambridge, to promote Chance UK's early intervention child mentoring program in October 2015.
