Pentwyn

Pentwyn is a farmhouse, likely dating to the 17th century, with significant alterations in the 18th and 19th centuries. The farmhouse is constructed of rubble stone with a slate roof. The main, eastern facade was remodelled in the late 18th or early 19th century, and was once roughcast or stuccoed. It now features a three-window range, with the right-hand windows set in a shallow, full-height bow. The upper windows are 12-pane sashes, although the centre one appears to be a recent insertion or renewal, all with stone voussoirs. A C20 casement window is located on the ground floor to the left, set within an original relieving arch which corresponds to a window on the western front. A six-panel door is centrally located within an open-gabled porch supported by thin iron columns; it is slightly misaligned with the window above. To the right of the door, partially walled-in, is the remaining half of an original ashlar chamfered Tudor-arched doorway. A further 12-pane sash window is positioned on the ground floor to the right, also with stone voussoirs. The original entrance is on the western side, where the upper windows retain stone mullions, leaded lights, countersunk spandrels, and hood-moulds. A three-light window is situated to the left and a two-light window to the right, the latter set slightly lower. A small, rectangular stone-framed light is found between these windows, featuring moulded jambs, which may be reused elements, above an altered central doorway with stone voussoirs, which has been narrowed. A pair of C20 windows in a red brick frame are present on the ground floor to the left, while a single C20 window is located on the right, retaining an original relieving arch. A wall-face chimney has been rebuilt in the 20th century to the right of the centre. The south end wall is windowless and roughcast.

Attached to the north end is an outbuilding of rubble stone with a corrugated iron roof. It includes a loft window to the west, a ground floor plank door to the east, an open ground floor to the north with a stone pier, external stairs to the left leading to the loft, and a gable infilled with corrugated iron.

The interior likely began as a two-room plan with a cross-passage but has undergone considerable modification. The entrance opens into a large, south-western kitchen which narrows at the southwest corner with a lower ceiling in two bays; stepped hollow stops on the centre beam indicate this section was divided from a room behind after construction. The kitchen then widens, with a higher two-bay ceiling, featuring similar stops to the beams. However, a beam to the right of the entrance exhibits a chamfer only on its northern side. A timber and painted brick partition creates a stair hall behind the kitchen. The south end of the kitchen has a mostly blocked fireplace, and a wall recess with an oak lintel. The south-eastern room contains the ends of three beams with stepped hollow stops. The stair hall features a Tudor-arched plank door and a late Georgian staircase against the east wall, with stick balusters and three turned newels. The north-eastern ground floor room has a shallow bow, a panelled soffit, and a late Georgian six-panel door. The first floor retains similar beams and a post-and-panel partition, with chamfered posts and scribed mouldings, and a Tudor-arched door. Leaded glazing is present in the arched windows, along with iron opening lights. The southwest store-room has a remnant of reed or bead moulding in the plaster by a beam. A small fireplace and recess are present to the right, and there are former winding stairs to the loft, now disused, rising from the north-eastern room.
