21, Gold Street

21 Gold Street is a house built in 1851, which has been refurbished in the 20th century for use as offices. The structure features a timber frame with plaster, red brick, and roofs made of slate and clay tiles. It has an L-shaped plan and consists of two storeys with a partial attic.

The front (west) elevation is made of red brick that has been ruddled and tuck-pointed, displaying five bays and a four-window range. The windows have stuccoed voussoirs and are sash windows with thin glazing bars, arranged in a 3x4 pane configuration. The doorway is located in the second bay from the south and features a moulded cornice and hood, a moulded architrave, an over-light, and a door with six moulded panels. There is also a smaller, simpler doorway in the north bay, which has a stuccoed voussoir, an over-light, and a six-panel door. The slated roof has a ridge stack at the north end and two additional stacks located behind the roof at the centre and south end.

The rear (east) elevation includes two conjoined brick and slated gabled wings, and to the north, there is a deeper timber-framed wing with a clay-tiled gambrel roof. A 20th-century deep ground floor lean-to porch, which is felted, is situated in the internal angle. The brickwork features some burnt headers, scored pointing, and an inset stone plaque inscribed with "C.P. 1851." The first floor has three sash windows with ruddled and tuck-pointed voussoirs, glazing bars, and 3x4 panes. The ground floor has a 20th-century two-light window with a concrete lintel and a 2x2 casement window. The porch has a plain door with an upper light and a single-light casement window. The north wing features 20th-century casement windows, with four, three, and two lights respectively from the ground floor to the attic, and a single-light 20th-century casement window in the first floor of the south return wall.

The south end elevation shows the gable of the street range and a short rear wing in red brick, with some burnt headers and scored pointing. There is a single ground floor 20th-century rear window with a concrete lintel and three lights.

Inside, the principal blocks are plain and have been refurbished in the 20th century. The north wing has some exposed 19th-century framing members made of pine, including tie-beams with knee braces and floor joists of a deep, thin section. It is likely that the north wing predates the brick building, which underwent significant enlargement in brick in 1851.
