Barn at Gwern Leyshon Farm

Random rubble barn with bigger quoins and stone-tile roof. Facing the yard is a lower, hipped-roof porch R of centre faced with hammer-dressed stone, a shallow brick arch and a sandstone key with the date 1836 in a diamond panel. Two pairs of ventilation slits flank the porch behind added lean-tos. Further L is a stable door and window and a blocked former granary opening beneath the wall plate. The L gable end has external steps leading to a granary door (all overgrown). Against the R gable end are later ranges. The rear was inaccessible at the time of inspection (July 1998).

The barn has a 5-bay roof of machine-sawn trusses, consisting of tie- and collar-beams. The cart passage retains a flagged floor. In the dividing wall between the barn and stable the gable end of an earlier, lower building can be seen.
