Granary and malthouse at Blaengavenny Farm

The granary and malthouse at Blaengavenny Farm is a building of probable late medieval origins, though significantly altered and extended in the 19th century. It is constructed of thinly coursed red sandstone rubble, with plastic slate roofs. The building is arranged over one storey and an attic, and comprises two distinct sections.

The earlier section, at the eastern end, has a lower roofline and no chimney. It may have been heightened at some point and was originally detached from the second section, with an infill occurring in the 19th century. The gable wall features an unglazed timber window with a central mullion, set beneath a timber lintel, which appears to be a 19th-century replacement. Above this is a modern 2-light casement window. The left wall is blank, and the entrance is now within a covered way connecting the building to an outhouse and the farmhouse. The right wall contains a ground-floor window similar to that on the gable, plus a smaller modern window to the right. The steep roof pitch suggests it was originally thatched; when the roof was raised, the original timbers were reused, preserving the pitch, which is too steep to have carried stone tiles.

The building was extended westwards and heightened, likely in 1881, when an attic storey was added, housing a granary, with a malt kiln situated below. A gable end features external stairs leading to a granary door. A doorway within the yard wall is accompanied by a modern window to the right, both set under a concrete head. The rear wall clearly shows the rebuilding and extension, featuring a modern window under a concrete head. A steeply pitched roof incorporates a centrally rebuilt stone stack serving the kiln.

The older section has an inserted floor supporting rough beams. A clean timber-framed partition divides the first floor. The principal rafter roof, spanning three bays and featuring three tiers of trenched purlins and a ridge piece, has been replaced due to timber rot at the apex of the trusses. While many timbers exhibit smoke blackening, alterations and rebuilding mean not all are blackened. The roof structure suggests a late medieval open 'hall’, likely a detached kitchen originally associated with Blaengavenny Farm, with its entrance positioned opposite the rear door of the farmhouse's cross-passage. The western section contains a malt kiln on the ground floor and a granary on the upper level, with a 19th-century sawn timber roof.
