[2] The building was designed in the neoclassical style, built in buff brick with an ashlar front and was completed later that year.

[1] A woven coverlet maker, Gilbert Hannan, founded a grammar school for twelve poor boys in the assembly room in 1672,[4] and the building was converted for municipal use as the local town hall in 1760.

[3] The assembly room was originally accessed using a stone staircase inside the building but, in the early 1840s, extensive restoration work was carried out at the expense of the local member of parliament, John Abel Smith.

[5] Following completion of the works, magistrates' court hearings, which had been held in the Angel Inn in North Street, were relocated to the assembly room in the town hall in April 1848.

[9] After extensive investigations to confirm the existing ownership of the property, the building was conveyed to a new charitable body, the Midhurst Town Trust, in February 1910.
