8 Mount Stuart Square

8 Mount Stuart Square is a building of Flemish Renaissance style, constructed in the 16th and 17th centuries, and altered in the late 19th century. It is located within a group value context. The building rises to three storeys and has one window. It features a slate roof and brick chimneys. The exterior is stuccoed, with some scribing to mimic ashlar, and has a rusticated ground floor with a shallow plinth. A cornice and parapet cap the building. Second-floor windows are broad tripartite openings articulated by Doric pilasters, with a Venetian-style motif and a small shell tympanum above. There is a cornice over the rusticated ground floor. The ground floor of number 8 has a square-headed doorway and, to its right, a large three-light shop window with modern round-arched glazing.

The ground floor of number 9 has a bathstone commercial front from the late 19th century, dated 1889, set on a grey stone plinth. The design is by architect W D Blessley, and incorporates a deep entablature with a cornice, the inscription 'Perch Buildings' displayed in bronze lettering on the frieze. The architrave features decorated keystones and a cartouche above the doorway, where the entablature projects forward and is topped by a small triangular pediment. The doorway is flanked by pilasters with swagged capitals. To the right of the door, there are three windows with bulbous columns, and decorated panels within the plinth below.
