Description

No. 300 on Roman Road is a house dating from around 1800, with some 20th-century alterations. It is timber-framed and plastered, with a peg-tiled roof and end stacks. The building has a rectangular shape with a rear outshut and a 20th-century rear wing and adjoining porch, which are not of special interest. The overall plan is now L-shaped and the house is two stories tall.

The front elevation features three windows, all with plain frames and 20th-century renewed sashes that have horns and glazing bars, arranged in a 3x4 pane configuration. There is a central 20th-century peg-tiled gabled porch with a four-panelled door that has flush and bead-moulded panels. Each side of the porch has a 20th-century casement window with four panes.

The west stack is original, while the east stack is rendered except for the rebuilt top. The east end elevation shows the house and outshut with an external stack and a 20th-century two-light casement window on the first floor. The west elevation is similar but has an internal stack and a ground-floor 20th-century two-light casement window. The rear elevation is largely obscured by the 20th-century addition on the west end. The outshut on the east end features a wooden triple casement window with segment-arched heads, and there is a central dormer with a similar window and a leaded gable.

Inside, there is a central passage and landing with a rear stair that was rebuilt in the 20th century. The partitioning to the rooms on either side and the outer wall framing are made of elm, with slender studs and rudimentary primary bracing. The first-floor joists are made of similar material, as well as softwood. The ground-floor fireplace at the west end projects into the room; it has been rebuilt in the 20th century, but the original brickwork with wide lime mortar joints is exposed in the first-floor room above.
