Description

The Old Hall is a two-storey building featuring a hipped slate roof and two brick chimneys. Its exterior is finished with painted roughcast rendering, complemented by a smooth plinth band and band courses. The front elevation is low and broad, with five windows and a central gable that contains a round-headed attic window. On the first floor, there are twelve-pane hornless sash windows, arranged in a shallow grouping of 1+3+1. The central doorway has a pair of glazed double doors with a lamp above, while doorways at each end feature six-panelled doors.

On the left side, there is a smooth-rendered wing showing traces of scribed 'coursing'. This wing has two twelve-pane sash windows on the first floor, and on the ground floor, there is a panelled door beneath a modern canopy, with a square casement window to its left. The right side has a wing made of painted rubble with a string course, containing one square window with a modern frame and shutters. There is also a later 19th-century extension that includes a half-glazed door under a canopy.

Inside, the building retains timber-framed partitions and shows evidence of former partitions, such as mortices in the exposed ceiling beams. All three dwellings within the property feature identical staircases, likely dating from the early 19th century.
