Barn at Llangwm Isaf

The barn at Llangwm Isaf is a Grade II listed structure built from rubble stone and topped with a pantiled roof. The walls feature thin stones, and the door heads are also made of stone. The front of the barn has a central high opening with a cambered arch, which has later barn doors added in front. There are vent loops on each side of this opening.

To the left of the ground floor, there are two doors, while the right side has stone steps leading outside. Attached to each end of the barn are lower ranges; the right one is lofted and has a blocked loft door, with the right corner rebuilt in blockwork. The left range is single storey and features late 19th-century red brick framing around a door and window on the right, with a pair of casement windows in the centre. The interior was not available for inspection at the time of the survey.
