Cefn Mably

Cefn Mably is a moated manor house, largely of the 16th century, with a parlor cross wing to the left and a lower gallery terminating at the left end in a projecting chapel. A service block is arranged around a central courtyard to the right of the hall. The building is constructed of rubble sandstone with limestone dressings, with fragments of stone-tile roofs (mostly now missing) and projecting eaves. The hall and service block have exposed steel trusses.

The hall itself is three bays, with the bay to the left advanced and formerly under a hipped roof. A sash window in a segmental-headed architrave was added to the upper storey in the early 18th century; the other bays originally held similar windows, although these are now destroyed. Contemporary attic dormers have also been lost. The two-bay parlor possesses similar sash windows and architraves. The gallery has late 19th-century windows, with three mullioned windows under relieving arches on the lower storey. A fourth window on the left was converted into a doorway for a hospital, and there are five three-light mullioned windows in the upper storey. A previous advanced bay at the left end of the gallery retains 16th-century four-light mullioned windows to the south gable end, beneath a stone end stack.

The chapel has a three-light Perpendicular window to the south (the liturgical east end) and diagonal buttresses. A gabled bellcote holding a single bell sits on the ridge between the nave and chancel. An overgrown porch is on the west side, and a three-light square-headed Perpendicular window is in the east wall.

The parlor and the south range of the service block have tall red-brick stacks. The doorway to the original cross passage has been knocked out and blocked up. The two-storey service range east of the hall comprises seven bays and a brick string course between the floors, with openings featuring brick jambs, but the windows are now missing. The end wall is two bays, and to the right of this, the east wing of the service block is set back, featuring five bays and mullioned windows. Upper-storey windows are set within gablets, and there are two paired stone stacks. The north wing of the service block has a central gateway to the courtyard, now boarded up, flanked by cross windows. Two windows are blocked further to the left, and late 19th-century cross windows are on the upper storey under gablets. The east wing of the service block is higher, with cross windows in its gable end and west return wall.

Behind the hall is a lower two-storey projection, to the right of which is a stair projection with mullioned windows. Most early features appear to have been destroyed in a 1994 fire; the building was not inspected at the time of the survey.
