Description

Gledlom is a large L-shaped farmhouse facing a small 18th-century walled garden. It comprises two distinct elements: an earlier, lower house built across the slope, and a later upper house positioned at near right angles up the slope. Both are 2-storey structures of rubble stone with roofs of 19th-century local slate, which replaced the original thatch.

The lower house has a higher eaves line than the upper house. Its end stack is rendered brick. A central gabled brick porch has been added, its doorway now converted to a window. The original windows feature stone mullions with plain chamfer: a 3-light window to the right of the porch, and in the upper storey 3-light windows to the centre and right, with a 2-light window to the left. An added projection under a hipped roof is built against the left gable end, with single windows to the front and side, and a door and window to the rear. The rear elevation has two 2-light casements added around 1900 in both storeys, and a small former stair light in the upper right.

The upper house is dominated by its fine 2-storey porch, offset left of centre and with a higher eaves line than the main house. The doorway has a moulded segmental head and half-glazed door, above which is a dated tablet bearing the initials WW and a coat of arms. The upper storey of the porch contains a 2-light window with Gothic Y-tracery and small-pane metal glazing. The apex is crowned with an octagonal stone pinnacle with ball finial. To the right of the porch are an inserted doorway and a window with late 20th-century detail, with a further casement window in the upper right. Against the right, uphill, gable end are brick steps leading to an inserted doorway with brick jambs and a half-glazed door, replacing an earlier doorway with external steps shown in an 18th-century drawing of the house.

The rear of the upper house has a 2-light stone mullioned window in the lower left lighting the kitchen, with a small inserted window to its right and a former first-floor doorway now blocked and converted to a 2-light window. A single-storey gabled projection added between 1850 and 1871 is positioned left of centre, with an inserted window in its right side wall. To the right of the projection are windows renewed in openings of around 1900, followed by a massive external hall stack with a tall shaft. To the right of the stack is a lean-to ty bach (outdoor toilet) of around 1900 with a boarded door and wood-framed window. The downhill gable end has a 3-light window to the hall with ovolo stone mullions and hood mould, now enclosed within an added glazed conservatory. Above is a 2-light casement inserted around 1900 to the upper storey, with blocked former pigeon holes beneath the apex.

Internally, the hall of the upper house is now subdivided by a corridor running across the front, an alteration made around 1900, though a single cross beam with broach stop survives. The hall fireplace has an unmoulded timber lintel. The hall fireplace in the lower house is reduced, but evidence for an original fireplace stair is provided by an arch beside the fireplace in the upper storey and a small stair light in the rear wall. The mullioned windows in the lower house have flat internal faces.
