Description
The outbuilding at Gwarcwm Isaf is a single-storey structure built from rubble stone and topped with a slate roof that meets stepped stone gables. On the left side, there is a stable featuring a small window and a door, both of which have timber lintels. The rest of the building contains a cow-shed with four doors that have stone voussoirs.
Although the interior was not inspected, a report from 1980 mentions that the roof trusses have low collars and notched lap joints, along with square-section through purlins.
