Description
Red House Farmhouse comprises two distinct phases of construction, likely dating from the earlier 16th century and the late 17th or early 18th century, with more recent alterations and renovations. The external walls are roughcast and painted a cottage-pink colour, while the roofs are covered in Welsh blue slate, except for the front elevation which features graduated grey stone slates. The building follows a T-shaped plan.
The original section is a three-bay range, initially cruck-framed and single-storeyed, but later adapted to become a 1½-storey structure. A lean-to extension was added on its northwest side, probably in the 19th century, and it now serves as a rear service wing to the later addition, which is a five-bay, three-windowed, two-storey range built across the southwest end.
The main range exhibits a plinth and a broad band above the ground floor, both running continuously around the façade, which now faces the garden. This front has a regular and symmetrical appearance with a centrally positioned segmental-headed doorway. There are two small segmental-headed three-light casement windows at ground floor level, with restored glazing, and three matching casements at the first floor. Gable chimneys are visible. The rear eastern bay has a similar casement window on each floor, and three renovated dormers are incorporated into the roof. The eastern side of the earlier rear range, abutting the front range with its eaves just above the band, includes a segmental-headed doorway near the junction, a rectangular three-light casement window, a large doorway close to the rear angle, and a sloping dormer offset slightly to the left. A tall chimney rises from the junction of the roofs. The rear gable wall features two small windows at ground floor level and a third above, all with segmental-headed three-light casements, and a smaller two-light casement is found in the end wall of the lean-to extension.
Within the rear wing, the first bay, adjoining the main range, retains most of a full cruck truss with exposed blades on both floors. A partition wall in this bay is constructed of square-panelled timber-framing. Abutting these features are large, chamfered ceiling beams supporting floor joists of unusually triangular section; the beam next to the partition crosses the lower part of the upper tier of panels, indicating a later insertion of the upper floor. The northwest side-wall of this range displays square-panelled timber-framing on a rubble plinth, visible in the lean-to addition. In the end room of this range, which is open to the roof, a complete square-panelled cross-frame is visible, including a principal-rafter truss with three queen-struts to the collar and V-struts above the collar.
The main range has stop-chamfered beams on both floors, probably made of chestnut, and principal-rafter roof trusses with slightly arched collars. The entrance hall, in the centre bay, contains a fine late 17th century framed newel staircase with a closed string, turned balusters, and a heavy moulded handrail. Due to irregularities in its construction, the current owners suspect that the staircase is not in its original location.
