50, Castle Street

No. 50 Castle Street is a house that was once a shop, featuring a core from the 16th century, an extension to the east from the 18th century, and a 20th-century addition and refurbishment. The building is timber-framed and plastered, with basic 20th-century pargetting, a peg-tiled roof, and red brick stacks. It has an L-shaped plan, consisting of a street range and a deep east end addition from the 20th century. The house is one and a half storeys high.

On the north elevation, the front has a low range with a central roof break, a simple pitch to the west, and a gambrel roof with a half hip to the east. There is a stack at the junction of the roofs and a second small stack through the east roof hip. All windows are metal casements with leaded glazing, including two 3-light windows, one 2-light window, and two gabled dormer windows, one on each roof, with 2-light metal casements.

The south elevation at the rear is similar to the front but features a deep 20th-century flat-roofed single-storey brick extension on the east half. It has a plain door with a single upper light and a 4-light casement window with glazing bars, consisting of 8x4 panes. The west end has large glass sliding doors leading to the garden, which has 4 panes, and two flat-roofed dormer windows: one 4-light window with 8x4 panes and one 3-light window with 6x3 panes.

The east end elevation has a half-hipped gable with a small stack, and the front wall plate is visible. There is a small single-paned ground floor window with a 2x3 paned casement in the gable, and a 3-light window on the rear addition with glazing bars, consisting of 6x2 panes.

Inside, the west end wall shared with No. 48 has well-made 16th-century heavy studded framing, while the rest of the unit to the west of the stack is also heavily framed. The wall plate junctions at the west end suggest a construction break, indicating that No. 50 was added to No. 48. There are remnants of red paint, possibly from the 17th century, on the framing. The rest of the house features slender 18th-century construction with side purlin roofs throughout made of softwood, and the stack brickwork is of late 18th-century type. The house reflects the 16th-century single-storey timber-framed construction seen in other buildings along Castle Street to the west. Remnants of open hall framing in No. 48 suggest that Nos. 50 and 48 may have once been part of the same house, originally consisting of two bays.
