Description
This is a house, likely dating from the mid-18th century, that was significantly enlarged and altered in the mid-19th century, with a later 19th-century addition designed by G. E. Street. The construction uses slatestone and granite rubble, with 19th-century brick dressings, and the G. E. Street addition is built of coursed metamorphic stone rubble with granite banding and dressings. The roof is slate, hipped over the earlier 19th-century section, with a gable-end to the G. E. Street addition and side and gable-end stacks.
The house originally had a three-room plan, rebuilt in the early-mid 19th century. The front facing Fore Street was altered to provide a passage leading to the rear of the house. The G. E. Street addition to the west includes a porch set into the angle of the earlier range and has a one-room plan. The original layout was an “L” shape.
The Fore Street facade has the end of the first range on the right, two stories high with two windows. At the first floor are two 12-pane sash windows. On the ground floor to the left is a 16-pane sash window with a cambered brick head, and a six-panelled door with an overlight to the right. The G.E. Street addition to the left is slightly set back and features a porch with a pitched roof set into the angle. The porch has a triple lancet window with colonnettes and corbels. A doorway to the side has a shouldered head, and the inner doorway has double half-glazed doors with Gothic margin glazing and a four-centred arched fanlight with Gothic interlaced glazing. Two gabled dormers, each with a two-light casement with a shouldered head, are present. The gable end of the G.E. Street addition has a three-light mullion and transom window with chamfered, trefoil headed lights at ground floor level; a similar oriel window is located at first floor. A brick chimney stack is set into the left side. The left side of the main range has two 20th-century 12-pane sash windows at first floor, with brick segmental heads, and a 12-pane sash window under the eaves. The right side has two doors, a 16-pane sash window and a 12-pane sash window under the eaves. An extension is located behind the 19th-century building, featuring a first-floor addition built in brick.
Internally, the ground floor room of the 19th-century building has shutters with strap hinges. The first floor stair is extended with a single panel of balustrade to allow access to the first floor room in the addition. This room has a roof of three bays with chamfered principal rafters and collars, featuring run-out stops; it also has a four-panelled door. A marble chimneypiece was introduced in the 20th century.
