Castle Dyke Farm and Attached Outbuilding and Rubblestone Wall

Castle Dyke Farm is a farmhouse, now a house, dating from the late 16th to early 17th century, with some alterations. It features a rendered exterior and a steeply-pitched slate roof that is half-hipped to the right, along with a tall rendered stack finished in brick on the front right. The building has a rectangular plan with a projecting gabled porch located to the right of the center. Inside, there is a central hall heated by a rear lateral stack, and a single-storey lean-to on the front right. The adjacent No. 47 forms a cross wing to the left.

The exterior is two storeys high with a two-window range. The porch includes a 19th-century horned 6/6-pane sash window in a forward frame on the first floor. The porch is supported by granite columns with rounded capitals that are now part of the enclosing walls, featuring a plain semicircular arch at the front. The original 17th-century studded oak door consists of three wide planks and has heavy wrought-iron strap hinges along with a moulded lintel. The range to the left, which is attached to No. 47, has 19th-century two-light casement windows on the ground floor and a gabled dormer.

A notable feature is the rubblestone wall, approximately 5 meters high, attached to the front right corner of the farmhouse. This wall extends forward about 30 meters and meets a frontage wall with quartz blocks to the left and an 18th-century outbuilding adjacent to the road on the right. The outbuilding is constructed of uncoursed local rubble and has a hipped corrugated-iron roof. It features a timber lintel over a central throughway, doveholes beneath the eaves on the rear elevation, and timber lintels over loft and window openings, with a doorway to a stable on the right.
