Description

23 Hannah Street is part of a group of buildings at 22, 23, and 25 Hannah Street, constructed of sandstone ashlar and red brick with baroque detailing. The roof is made of artificial slate with ridge tiles. The building has three storeys and a basement, featuring ground floor shops and former offices that are now club premises above. The original frontage included a central decorative gable with lower decorative wings on each side; the right wing is included in the listing despite being partly remodelled.

The ground floor has modern shop fronts for Nos 22 and 23, while No 25, which was originally a baker's, features a cast metal inscription band beneath a curved shopfront window. This shopfront has a slender mullion and a decorative recessed door to the left with a large glazed panel and a steep curved pediment above. The butcher's shop at No 24 is listed separately.

On the first floor, the main frontage has five windows: one central round-headed window and four rectangular windows with renewed glazing, separated by pilasters that have deep keystones reaching up to a broken pediment above each window. The central keystone extends to a string course above, and all spandrels are filled with richly carved swags. The upper floor features three similar round-headed windows with fluted pilasters, decorative Ionic capitals, and cartouches with grapes on either side. Above these is a recessed decorative rectangular inscription plaque reading 'T E', adorned with carved corn and maize motifs and an engraved date of 1905.

Channelled pilasters on the sides support scroll brackets, from which rises a Flemish gable topped with a moulded coping and five urns. The main roof, visible from the side, has three gables. The right wing is rendered and has six round-headed windows with replaced glazing and a remodelled battlemented parapet. A postcard painting from before 1918 shows the central gable in a form very similar to its current appearance, flanked on both sides by wings each with two lower Flemish gables.
