Former Farmhouse at Bryn Tangor

Agricultural range in local slatey stone with part asbestos, part slate roof. The slate-roofed north half of the building, including the two bays which survive from the mediaeval farmhouse, is a single storey range standing on level ground. Heck doors to front. The south half of the building is a lofted range for livestock, built on rising ground. This has three heck-doors and a loft hatch.

The part of the agricultural range which contains the two domestic bays separated by a cruck truss is about 7 m in length by about 6 m wide. The truss consists of two large and well-shaped blades extending from about waist height to the apex. The feet of the blades disappear into the stonework. At their thickest the blades are about 175 by 400 mm. A high collar beam is morticed into the blades, and there are arch braces to each side with multiple pegged tenons both to the collar beam and to the blades. The soffit of the collar beam is notched at centre to receive the top ends of the braces. Above the collar beam is a short king post decoratively carved, morticed into the blades at apex; the blades abut each other vertically. The arch braces and the blades below are carved on the lower arris with a staff moulding at each face. There are stave holes both above and below the collar beam showing the partition was complete. There are also mortices beneath the arch braces each side for two lost posts.

Two early purlins survive on the east side and there are two modern purlins on the west side. There is no windbracing or any mortices for windbracing; the truss has been supported against racking by an inserted strut from the wall to the south.
