L-plan barn ranges at Maesllech

Two barns forming an L-shaped range, comprising the earlier lower barn on a sloping site, with the later barn built at right angles to it across the slope. The lower barn has a high rubble-stone sill. Its walls are simple box-framing now concealed by weatherboarding and corrugated iron sheets. The steeply-pitched roof has a half-hipped lower end and has a corrugated iron roof. The threshing bay has full-height boarded doors on the E side, but on the W side facing the yard it is infilled by a low blockwork wall with corrugated sheets above.

The upper barn is rubble stone with corrugated iron roof. Facing the yard on its S side is a full-height doorway in the angle with the lower barn, with replaced boarded and corrugated iron doors, L of which are 2 ventilation strips. A lower cart shed, added in the late C19, is attached to the L gable end, obscuring stepped ventilation strips. It is of 2 units, open-fronted to the yard with slate roof on the R side and corrugated iron roof on the L side. A lean-to is built against its gable end with boarded door under a wooden lintel.

The R gable end of the upper barn projects slightly in front of the line of the lower barn. Its gable end has 2 ventilation strips, and a loft doorway in a corrugated iron gable. The N side wall has a full-height doorway with double corrugated iron doors offset to the R, flanked by pairs of ventilation strips on both sides. The cart shed has a rubble stone rear wall.

The lower barn has 3 central bays with narrower outer bays, and retains 4 cruck trusses with lapped tie beams and collar beams.
