9, Castle Street

No. 9 Castle Street is a house dating from around 1450, with later additions. It features the western half of a jettied range that is timber-framed and plastered, with coved eaves and a peg-tiled roof. The building has a T-shaped plan, consisting of a street range and a rear timber-framed wing that has a later lean-to addition on the eastern side, which overlaps with No. 11. The house is two storeys tall and has a cellar.

The front (south) elevation has a continuous jetty that aligns with No. 9. The details of the framing are now covered with plaster. On the ground floor, there is a rectangular bay window with glazing bars arranged as 1x3, 3x3, and 1x3 fixed panes. The street door is located to the east and features an early 19th-century plain door-case with a six-panelled door, where the upper panels are glazed. Between the door and the window, there is a moulded rail and shutter hinge recesses on the window frame for a folding shutter.

On the first floor, there are two 2-light sliding sash windows with moulded architraves, each with 4x3 panes. The rear (north) elevation showcases a prominent timber-framed wing, which is plastered but reveals some visible principal members. There are two red brick stacks: one at the northern end of the wing and another at the junction of the wing and the street range. The ground floor at the northern end has a 20th-century door with upper glazing featuring 4x4 panes and lower boarding. On the eastern side, there are sliding sash windows with 4x4 panes on both the ground and first floors. To the east, there is a shorter lean-to with a slate roof, which has a single 2-light casement window in the northern end wall, also with glazing bars and 4x3 panes.

Inside, the ground floor ceiling joists in the street range are exposed and show two phases of construction. To the east, there are heavy flat-laid joists with soffit tenons and Roman numeral carpenters' marks. To the west, there are slender re-used joists at right angles to the others, typical of the late 17th century. The first floor features jowled corner posts. The framing of the rear wing has mixed ground floor studs, with a shutter groove in the middle rail on the western side. The first floor tie-beam has pegs for arched braces. The principal stack at the back of the street range is constructed with narrow 17th-century bricks where it has not been rebuilt. The ground floor fireplace has been remade in the 20th century, featuring a late 18th-century cast-iron surround with an eared architrave and Adamesque detail. The cellar retains a chute from the street and a simple rear window.
