Description

The barn at Maes-y-pandy is a Grade II listed structure built from regular local stone rubble, resting on a foundation that includes quartz boulders. It features a slate roof between raised boulder gables. The building comprises a main five-bay barn with a rear wing on the northeast, which contains open-fronted cartsheds and a granary above.

The barn has a central pair of doors framed in timber with a central post, and a concrete lintel has replaced the original timber lintel around 1975. There is a similar door on the northwest side. The barn includes two tiers of ventilation slits, pitching doors at each gable end, and a new opening in the northeast gable to accommodate farm machinery. Additionally, a two-bay cart house has been added to the rear, with timber-replaced lintels and a small glazed window for the granary loft.

Inside, there are four tie beam trusses with raking struts.
