10 and 12 Castle Street

10 and 12 Castle Street are a pair of early 19th century houses that were converted into shops in the late 19th century and extended at the rear in the 20th century.

The buildings are made of brick with timber shopfronts, topped with a roof of slate and plain tiles. Both houses are three stories tall, with a basement and a later mansard attic. The brown brick is laid in Flemish bond, and the window openings on the first and second floors feature gauged brick and flat arches. A stone cill band runs above the ground floor, and each house has a tall brick chimney stack.

12 Castle Street features a timber shopfront with transom glazing, flanked by a pair of stucco Doric pilasters that rise to a Doric entablature supporting the shop fascia. The recessed entrance door appears to be from the 20th century. The first and second floors have a tripartite multi-pane window, and there is a multi-pane, flat-roofed dormer in the mansard. A plain cornice, likely made of timber, sits beneath a rendered parapet.

10 Castle Street has a six-panel door with a radiating and wreathed fanlight above, set within a stuccoed round-arched architrave and gauged brickwork. It is accessed by a set of rounded steps. The shopfront is simple, featuring two plate glass windows and a glazed door. The first and second floors have the same window design as number 12, with the addition of a 12-pane sash window above the main doorway. There is a dentil brick cornice and parapet, and the mansard has two flat-roofed dormers with uPVC multi-pane windows.

The rear elevation of both houses displays a variety of timber sash windows, including a large stair window in the central bay of the second floor, and three dormers in the mansard. Number 10 has a series of later 20th century extensions projecting north from the rear, constructed of brick with flat roofs and casement windows.
