Description
Llangwm Isaf is a farmhouse that features a rendered exterior with concrete tiles and brick end stacks. It is two storeys high and has an L-plan layout, with the older section located to the north, which has an end entry that was rebuilt in the later 20th century. The north facade displays irregular window arrangements, including a pair of casement windows to the left of centre and a triple casement window to the right, positioned under the eaves. The right window retains a recessed chamfered oak frame from a former mullion window. On the ground floor, there is a pair of casement windows on the left, a triple casement window in the centre, and a small three-light timber mullion window with ovolo mouldings on the right, all topped with stone dripstones.
The left gable end, which was rebuilt in the 20th century, features three windows on the first floor, along with a door and two windows below, mostly consisting of horned four-pane sash windows. A gabled hood is present over the door. The rear wing includes two small gabled dormers, one on each side of a large rendered wall-face stack. To the left of the stack, there is a two-window range, with a triple casement window and a pair of casement windows above two doors. The left door is broader, while the right door has had its timber gabled hood removed around 1999.
The property is not available for inspection, and further details noted by Fox & Raglan are referenced above.
