Stable Block at Glan Gwna Hall

The stable block at Glan Gwna Hall is a simple Classical-style building dating to the 18th century. It has a square courtyard plan, with single-storey ranges facing east, north, and west, and a one-and-a-half-storey range facing south. The south range contains the principal entrance and is slightly higher than the others. The building is constructed of rendered brick with stucco lining, plaster quoins, and window dressings, including dripstones to the ground-floor timber windows with mullions and transoms. The roof is slate, with red ceramic ridge tiles and overhanging boarded verges, including to the dormers.

The south elevation features three windows on either side of a central gable, above which is a round-headed archway containing curved, half-height boarded doors. A string course runs below the archway, with a clock in a plain, moulded roundel positioned above. A small, pedimented cupola with a lead capping and weathervane rises from the ridge. Dormers break the eaves, providing reduced-proportion windows. An inserted doorway is present to the left bay, and an original panelled door is sheltered by a lean-to hood in the centre bay to the right of the archway. This section also has two red brick ridge stacks with grouped shafts, moulded bases, and capping. The west elevation has large, moulded roundels to the gable ends of the north and south ranges; the north roundel incorporates a wide doorway, while the south features two 3-light mullioned and transomed windows on the ground floor. The west range has altered door and window openings, and a tall, pyramidal spirelet flanked by slate-capped ventilators rises from the ridge. The north and east ranges have sash windows; the north range has a spirelet similar to that on the west range to the right of the gabled entrance. The inner elevations enclose a paved courtyard. The south range features a gabled hayloft door breaking the eaves, a wide doorway in the angle with the west range to the right of the entrance archway, a 3-light mullioned and transomed window, and a gabled half-dormer to the left. The west range has two 3-light mullioned and transomed windows either side of a central doorway. The north range features a doorway to the far left and windows to either side of the entrance archway. The east range exhibits four open bays.

At the time of survey, much of the building was inaccessible. A ground-floor room to the right of the principal entrance arch contains a corner chimney breast with a decorative cast-iron fireplace.
