Description

Hall Farm, also known as Neuadd, is a two-storey house with an attic, dating from the 18th century. It comprises a main range with a gabled kitchen wing set back to the right, and a lean-to dairy attached to the right gable end of the house, with a further lean-to in front of that. The walls are roughcast and battered. The main house has a slate roof, while the kitchen and dairy have corrugated asbestos-cement roofs. Stone stacks are present in the centre and on the right of the main house (the central stack being partly rebuilt in brick), with a later brick stack on the left.

The front façade features a recently added porch, gablets flanking the centre on both sides, and windows installed in the 1960s. The rear wall contains a four-light window with ovolo mullions to the left of centre, and a similar three-light window to the left of that, set within a short lobby added from the main house to the kitchen. This lobby also incorporates a reset window from the original service room. A window has been inserted to the right of the central stack, replacing the original cross passage doorway. The left gable end has two windows, again 1960s insertions.

The lean-to to the right of the house has a corrugated metal roof and a full-height opening to the right. The dairy has a single boarded opening low down on its right side. The kitchen features a lean-to addition on its right side wall, with a boarded door facing the front. The rear of the kitchen has an external stone stack, external stone steps leading to a boarded granary door, and a low gabled projection on the lower right side which formerly housed ovens.

The original plan form of the house largely remains. Behind the added porch is the original cross passage doorway, which has a chamfered stone surround with broach stops and a Tudor-head arch. The door is boarded with studs and strap hinges, and a similar doorway survives from the cross passage leading to the hall. The left-hand side of the lower end of the house, on the left of the cross passage, retains chamfered cross beams with run-out stops, indicative of its original domestic use. The hall also has cross beams with cut stops. A post-and-panel partition partially survives behind later plaster, displaying a Tudor-headed doorway. The kitchen also has cross beams with cut stops, while the dairy has a flagged floor and salting slabs. The doorway from the kitchen to the stairwell has a Tudor head. The stair to the first floor has replaced the earlier stairwell, but the stair to the attic still has solid oak treads. The roof trusses are of tenoned collar beam construction.
