Barn at Penlan

The barn at Penlan is a 19th-century structure featuring three bays and is oriented to the east. It includes a cart shed and granary added to the northern end. The barn is built from rubble stone and topped with a corrugated iron roof, complemented by stone quoins. It has a central full-height entrance with planked double doors and ventilation slits on either side. To the right, the cart shed and granary are constructed of stone beneath a slate roof with brick quoins. The cart bay is open-fronted, and there is a planked door to the left that leads to stairs. The granary has weatherboarding on the front and a central loft hatch. A 20th-century corrugated iron lean-to at the rear partially obscures the barn, and there is a low lean-to against the southern gable end, which backs onto the house and is partly made of blockwork.

Inside, the barn features a central wagon bay flanked by low lofts on either side, which have boarded fronts supported by open timber framing. The roof trusses are designed with queen struts. Originally, there was a low stone wall at the base of the rear door, preventing a through-passage; the doorway now opens into the rear lean-to. One of the planked doors remains, along with the ventilation slits. An iron ring fixed to the ground in the lean-to is said to have been used to tether horses for operating a gin to thresh corn.
