Pen-y-cwm

Pen-y-cwm is a simple domestic Gothic estate cottage built in the late 19th century. This two-storey, two-gabled dwelling is constructed of snecked rubble with lightly dressed quoins. It features wooden window frames with diamond-lattice glazing, a slate roof with overhanging eaves and verges, and bargeboarding that retains remnants of apex finials. The axial stone chimney stack is topped with three tall octagonal chimney pots.

The cottage has a T-plan layout, consisting of a three-bay main range and a one-bay rear wing. At the center, there is a gabled porch that is timber-framed and slate-roofed, painted in black and white. The porch includes a corbelled semicircular outer arch, a studded outer door, open square-panelled timber detail on the gable, round-arched openings on the sides, an internal bench, and a half-glazed door. Above the porch, tucked under the eaves, is a very shallow two-light mullioned window.

To the right of the porch is a projected gabled bay, which features a cross-window on the ground floor and a bracketed wooden oriel on the first floor, both with similar glazing and a mono-pitched roof. The left bay, which has a raised gable, contains a transomed three-light window at ground floor and a small two-light mullioned casement at first floor. Between the floors, there is a square plaque carved with a quatrefoil that includes Lord Llangattock's monogram "Ll" and the date 1893. The joinery of all the windows is ovolo-moulded. The left gable end has a canted bay window on the ground floor and an oriel window above. The rear of the building has not been inspected.
