Trewern House (also known as Trewern Farmhouse) (South)

Trewern House, also known as Trewern Farmhouse, is a largely sub-medieval timber-framed farmhouse with painted brick infilling and a slate roof. The building features a 1½ storey main range from the late 14th or 15th century, which is set parallel to the road and consists of two unequal bays. At the eastern end, there is a mid to late 16th century two-bay cross wing that projects to the south. The early range, constructed with heavy vertical storey-high studs, was likely originally an open hall that was floored over with the addition of a stack in the late 16th to 17th century, possibly around the same time the cross wing was built. The Royal Commission on the Ancient and Historical Monuments of Wales has recorded a date of 1610.

The entrance is through a depressed headed opening on the south front, which is framed by a 19th century small gabled porch. The farmhouse has timber windows with modern diamond leaded glazing and features two 19th century two-light gabled dormers with shaped barge boards. The western gable displays an exposed frame and roof truss with a single purlin, which likely originally extended to cover an additional bay that is now lost. The cross wing has an attic that jetties at the front and includes shaped bargeboards. Detailed investigation indicates that the craftsmanship of the wing is similar to that of the early section of Trewern Hall.

Inside, the main 17th century stack has four cylindrical flues and brick ribs. The kitchen, located at the western end, features a renewed fire lintel on gritstone piers, adorned with two 13th century male and female heads, reputedly from Strata Marcella Abbey. The kitchen also has a very deeply chamfered spine beam and chamfered and stopped joints. Some panelled 18th century doors have been imported from Lancashire. The roof is said to have smoke blackened timbers above the ceiling. The cross wing, originally without windows facing the farmyard, consists of two unequal bays separated by a framed partition that contains a shaped doorhead, which appears to have been moved when the large stack was inserted. The fire lintel here rests on stone piers, with the chamfer being continuous, and there are deeply chamfered cross ceiling beams. The northeast corner of the cross wing was originally a salting room or dairy, and it features 17th century dado panelling with a narrow reeded upper panel.
