Barn with stable and granary at Cwrt-y-Brychan

The barn, stable, and granary at Cwrt-y-Brychan date to the 17th and 18th centuries. The main barn is constructed of rubble stone with a slate roof, incorporating a catslide roofline over the north double doors. To the left are two small loops (lighting holes). The right side features two renewed casement windows below a tall boarded opening that formerly served a cruck truss. The right end wall has three loops above a blocked window and two doors; the right door sits above the remains of a broader opening with stone voussoirs, while the other door and window are similarly framed with stone voussoirs. A rear southwest wing has a corrugated iron roof, with a broad lower opening lintelled with a 20th-century timber lintel, leading to a 19th-century brick-sided loft door. To the right of this is a 3-light mullion window with ovolo mouldings, dating to the 17th century. One window is present in the gable end, and the rear of the building has a single first-floor window. The rear of the main barn has a slate roof that extends to cover a brick lean-to that originally had four doors, two of which have been replaced with windows. This lean-to extends beyond the eastern end of the barn and is covered with clay tiles. A lean-to is also situated on the eastern end wall of the barn.

Inside the barn, the structure includes massive trusses and purlins that support a triple-purlin roof. The first truss from the east is a tie-beam and collar truss with a replaced collar. The roof has been raised within the first two bays. The second truss is a cruck truss with two collars, while the third is also a cruck with a tie-beam and collar. The fourth bay has massive triple purlins, and an inserted loft floor occupies the fourth and fifth bays. The fourth cruck truss lacks a collar and shows a cruck spur on the rear blade. A diagonally set square ridge beam spans the roof.

The added, lofted rear wing of the 17th century is open to the barn at upper level. It has massive oak framing below, possibly representing a remnant of the original timber-framed outer wall, which has largely been replaced with stone. This wing contains five tie-beam and collar trusses with triple purlins; the chamfered and stopped tie-beams are notched to accommodate joists for the attic floor, though most of these joists have been removed. Some square joists remain in one bay. Deep purlins and square, diagonally set rafters complete the structure. The first-floor walls are whitewashed, and a blocked window is visible in the gable. The ovolo-moulded timber-mullion window on the west side retains one original diamond mullion, while a similar 3-light window on the rear wall lacks one mullion. The ground floor features heavy beams and rough square joists, alongside two blank openings with chamfered and stopped lintels.
