Cloister Hall Farmhouse and attached wall, gateway and outbuilding

Cloister Hall Farmhouse is a building of probable 14th-century origins, with significant alterations and extensions dating to the 17th and 19th centuries. It stands near Frithelstock and incorporates elements of a former priory. The farmhouse is constructed primarily of rendered coursed slatestone rubble, with the front wall rebuilt in the late 19th century using squared and coursed slatestone. The roof is slate, with 19th-century stone ridge and end stacks on the front range.

The building’s layout and development suggest a former 15th-century hall range in the front section, evidenced by its thick walls and the remnants of a blocked window in the right gable. An adjoining through-passage and former service room are attached to a block at the rear, with a late 17th-century kitchen added to the right. The front elevation is a two-storey, three-window arrangement, featuring a projecting gable end to the left. A late 19th-century porch shelters a pointed-arched doorway flanked by lancet windows; the interior porch roof displays a late 19th-century arch-braced design with a 15th-century moulded cornice. A 15th-century granite doorway has a label mould over a moulded architrave with sunk spandrels. The front windows are late 19th-century two-light casements with glazing bars.

A rear wing includes a 17th-century studded and panelled door with an original iron ring, set within an ovolo-moulded frame, and a 19th-century stained glass window brought to the site in the 1970s. An early to mid 19th-century dairy outshut extends from the rear, featuring a plank door.

The interior of the front range, remodelled in the late 19th century, includes a fireplace dated 1680, with Ionic columns and richly carved decoration, originally located in a room to the left and brought to the site in the 1970s. The through-passage in the rear wing has chamfered ogee-stopped joists and a 16th-century studded door within a convex-moulded architrave. A tall room behind the passage occupies former ground and first-floor levels, featuring a reset 17th-century plank and stud partition on the right. The first floor has chamfered beams and a 17th-century plank door set within a chamfered ogee-stopped frame leading to the front range. The roof structure incorporates two jointed crucks with trenched purlins, a cambered lap-jointed collar to one truss, and straight principal rafters. The late 17th-century block added to the rear wing contains a former kitchen with a chamfered beam and stop-chamfered bressummer over an open fireplace.

Attached to the rear left is a 17th-century L-shaped wall of coursed slatestone rubble, incorporating a 17th-century gateway with a Welsh slate roof and a studded and panelled door within an ovolo-moulded architrave. An outbuilding extending from the house’s rear right corner is likely the former dorter range of Frithelstock Priory. Constructed of uncoursed limestone rubble with cob beneath the eaves, it features yellow brick dressings on a late 19th-century stable addition to the right, and a hipped Welsh slate roof. Historical records, including a Bishop's Visitation of 1400, suggest the site was originally a Prior’s Hall and used by the Prior to retreat from communal life.
