Barn at Garnllwyd

The barn at Garnllwyd is a 6-bay structure built from whitewashed rubble with a slate roof. It features central former barn door openings on both sides, with the opening on the southeast side being taller. This side faces the house and farmyard and has a later low range that projects to the left, which includes a cart-shed and a stone staircase against the gable end. There is a low chamber with a double door opening, a door, and one window.

On the rear elevation (southeast), to the right of the high central opening (where the original doors have been replaced by a glazed screen), there are a pair of double-glazed casements with false timber lintels that conceal concrete lintels behind, one at ground level and one at first floor level. The ground floor window has been inserted in place of a ventilation slit. The doors on the northwest side have also been replaced; there is a slit ventilator to the left and a doorway to the right with a cambered head. A similar door on the southeast side has been blocked by the addition of the lower range, and a new slit opening has been inserted above. There is a loft opening high up on the extreme right.

The gable ends are angled away from the side walls, suggesting earlier origins. The southwest gable has a modern casement window and a blocked pointed arch opening below; this wall has been rebuilt in blockwork and faced in stone. The northeast gable also features a modern casement at first floor level, with a pair of multi-paned French doors beneath. There is a chalybeate well located in the corner behind the lower range.

The barn has been subdivided and floored over as part of a recent residential conversion. The slit ventilators are broadly splayed, with one set at the end of a rectangular recess. The roof features king post trusses, along with some modern timbers.
