Description
County Hall is an 18th-century house that was rebuilt in 1845 by James Milne. It underwent remodelling by Edmund Law in 1890, with further alterations by Aston Webb around 1900. The building is constructed of ashlar and features two storeys. The ground floor has a rusticated appearance with Tuscan pilasters, while the first floor showcases Roman Ionic half columns. There are five sash windows; the ground floor windows have round heads with mask keystones, and the first floor windows are framed with eared architrave surrounds under alternating segmental and triangular pediments on consoles. The central pediment is broken, and all are set beneath oblong panels with swags in relief.
Inside, there is a half oval council chamber designed by Edmund Law in 1890, along with an entrance hall, octagon room, and staircase created by Aston Webb. County Hall is part of a group that includes the Judge's Lodgings, Sessions House, County Council Offices, and Nos 8, 8A, 9, and 9A.
