Corn barn, cartshed-granary and stable range, including stackyard wall, Borth Wen

This building is a linear farm range dating from the 18th century, aligned north-south. It includes a corn barn on the left, a lofted cartshed and stable in the center with a higher roof, and a second lofted stable on the right. There is a lean-to pigsty attached to the left gable. The walls are made of rubble with widely slobbered mortar, and the roofs are covered with small slates, some of which are grouted, along with tiled copings and ridge.

The corn barn features a narrow door offset to the left, one ventilation slit to the left, and two to the right, with timber lintels above. The winnowing door in the rear wall has been widened. An external stone staircase leads to a granary loft with two windows, which extends over the cartshed and feedroom/stable on the right. The granary has a boarded door, and its windows follow an agricultural pattern with small-paned upper lights. The one-bay cartshed to the right of the staircase has a cambered head supported by rubble stone voussoirs. The feedroom/stable to the right of the cartshed has a narrow door and an opposed door in the rear wall. The lofted stable on the right has a lower roof height, a single door on the main elevation, a small window to the right, and a blocked pitching hole on the right gable wall. It was formerly lofted and shows evidence of a rear staircase that led to servants' quarters.

At the rear (west) of the range is a square walled stackyard with three former entrances marked by massive gateposts, which are aligned consecutively along the south wall. The outer walls of the stackyard are constructed in clawdd style, featuring stone-faced earth banks with turf capping, and they border the road leading to Porth Swtan.

The corn barn consists of four bays with collared trusses, while the granary also has four bays with sawn and bolted collared trusses and torching on the underside of the roof. The feedroom/stable is a single bay with boarded doors on either side. The stable on the right has three bays and a vertically-split stable door; it was formerly lofted, with a servants' loft on the left and a hayloft on the right.
