Description

The granary and cowhouse located to the northeast of Treginnis Isaf Farmhouse is an early 19th-century two-storey outbuilding constructed from rubble stone. It features a grouted slate half-hipped roof. On the south end, there are external stone stairs leading to a loft door, along with a central stable door that has a fixed loft light positioned under the eaves. To the right on the ground floor, there is a small boarded light, and the rear of the building has two square windows on the ground floor. The ground floor appears to have been used as a calf-shed.
