Walled garden and attached outbuildings at Carreg Cennen House.

The walled garden and attached outbuildings at Carreg Cennen House feature an arched gateway leading from the east terrace of the house. The garden is enclosed by rubble stone walls that slope downhill on the west and east sides, with outbuildings located against the north side. The north side includes a greenhouse at the left end, followed by a small early 19th-century garden store that has a hipped roof and a four-light window on each side of the door. To the right, the garden wall serves as the rear wall of a farm-building on the opposite side. The wall continues with a straight joint at the right, and in the northeast corner, there is a later 19th-century outbuilding known as the apiary, which features recesses for bees in the south wall. This outbuilding is narrow and tall, constructed of rubble stone with limestone quoins at the southwest angle and a slate roof. It has three small putlog holes below the eaves on the south side, and above, there is a double row of eight shallow recesses with grey limestone lintels, sills, and splayed sides. The west gable has a doorway with stone voussoirs and a partially boarded door. The east wall of the garden has a door in the center, with the wall indented to the southeast, and an altered door at the east end of the south wall.

The apiary has a narrow interior without a loft, featuring a three-bay roof, whitewashed plaster walls, and a long timber shelf along the side wall. There is a window at the east end.
