Pentre-Uchaf Hall Including Attached Service Ranges, Outbuildings and Walls

Pentre-uchaf Hall is a small country house dating to the mid-to-late 18th century, with extensions added in the mid-19th century and later alterations. It is accompanied by attached service ranges, outbuildings, and walls. The main house is constructed of colourwashed red brick with slate roofs, the main range featuring graded slates with coped verges and carved stone kneelers. It originally comprised an L-plan with a short range to the rear on the left. A service range, built in the mid-19th century, connects the house to a late 18th-century stable block (partly converted to domestic accommodation in 1985), forming an L-shape around a courtyard.

The house is three storeys high, with a moulded stone eaves cornice, plinth, and chamfered angle quoins. It originally had three windows, with glazing bar sashes and plain stone wedge lintels. Prominent 19th-century canted bay sash windows were added to the ground floor on either side of the central entrance, which features a mid-19th century half-glazed door within a fluted pilastered doorcase, complete with a rectangular barred overlight and moulded flat hood. Integral end stacks have moulded capping.

The attached service range has four sash windows on the first floor (two to the left and two to the right), and two sash windows on the ground floor to the left. A third bay from the left features an elliptical arch with 20th-century double doors, while a 19th-century segmental-headed leaded casement is located to the right. The range has a toothed eaves cornice and a yellow brick ridge stack at the centre, along with an integral end stack to the right. A parallel gabled range extends to the rear.

The stables have a red brick and weatherboarded timber frame and a graded slate roof with raised verges. The left portion of the stable block, adjoining the service wing, was converted to domestic accommodation and contains 20th-century casements and double doors. Wide 20th-century hip-roofed dormers and a late 20th-century red brick ridge stack are also present. A catslide outshut is located on the projecting range of the courtyard. A curving red brick wall with stone coping sweeps round, screening the courtyard from the house. A short wall attached to the rear range turns at a right angle to the left and terminates in a late 18th-century tower-like outbuilding with a red brick construction, a low pyramidal graded slate roof, a square plan, a dentilled eaves cornice, and doorway and window openings.

The interior of the house, when inspected in October 1986, featured a winder staircase with a carved open string, stick balusters, and a wreathed moulded handrail in the central hall. The stables/barn exhibit visible framing, tall rectangular panels, and a single-purlin queen-post roof.
