Pillmouth Farmhouse and Attached Wall and Gateway

Pillmouth Farmhouse, dating from the early 17th century, features a late 19th-century extension and alterations. The building is roughcast over coursed slatestone rubble, topped with a gabled slate roof. It has a late 19th-century brick ridge stack, an external end stack of rendered stone on the left wing, and a lateral stack of rendered stone at the rear right. The farmhouse is arranged in an L-plan with a front left wing and has two storeys with a three-window range at the front.

A central two-storey porch from the 17th century is notable, featuring a sundial from the 18th century above an early 17th-century doorway. This doorway has a moulded stone architrave with leaf spandrels and a 17th-century studded door with a Norfolk latch, set in a moulded wood architrave with urn stops. The windows are late 19th-century two and three-light transomed casements with glazing bars in the upper lights, topped with flat rendered arches.

The right end of the front has a wing attached at right angles, which also has a two-storey, three-window range front, featuring a 20th-century door and 20th-century and late 19th-century two-light casements on the first floor. The left side wall includes late 19th-century and 20th-century porches and casements, with a late 19th-century extension to the rear left. The right gable end has a label mould over an early 17th-century four-light window with cavetto-moulded mullions and an ovolo-moulded frame.

Inside, early 17th-century doorways with cyma-moulded architraves flank the passage from the porch to the late 19th-century staircase. The room to the ground floor right has a flat stone arch over an early 17th-century open fireplace and a neo-classical style plaster frieze. The attics and the left wing have not been inspected.

Additionally, there is an L-shaped wall of stone and cob attached to the rear left corner, along with a 19th-century gateway that features a Welsh slate roof, reset early 17th-century mouldings on the jambs, and a 17th-century panelled and studded door set in an ovolo-moulded wood architrave.
