Pen Ithon Hall

Pen Ithon Hall is a two-storey, five-bay country house built in the Regency style, dating from the early 19th century. It is arranged in a U-shape, with projecting wings on either side that create a small service courtyard at the rear. The exterior walls are whitewashed roughcast, retaining some scribing on the side elevation, and feature rock-faced quoins. The roof is slate, hipped at the eaves, with a higher gabled glazed roof over the great hall. Brick stacks have replaced the original stacks, with smaller replacements on the east wing and behind the great hall. Small skylights have been added to the wings. Windows are set within architraves, mostly plain but some are moulded, and are sash windows with lying panes. The symmetrical south front has a simplified entrance with four attached Tuscan columns and a replaced door, topped by a glazed segmental pediment. Windows on the south front have six panes in the lower storey and four panes in the upper storey. The wider outer bays have full-height canted bay windows. The west elevation has a full-height canted bay, and a replaced half-glazed door. To the left of the door are two pairs of narrower stairwells leading to landings. Further to the left, in the four-window west wing, the windows are grouped as three plus one. The east elevation is similar, with steps leading to a cellar door under the canted bay; the lower right-hand window is blocked. The rear elevation has three lower-storey windows in the east wing, and a single blocked lower-storey window in the west wing.

Within the courtyard stands a three-sided lean-to canopy with a glazed roof supported by thin iron posts. The main range of the house has had its windows replaced. The wings have two-window elevations and replaced doors. To the north side of the courtyard is a service range built of rendered walls with rock-faced quoins and a hipped roof of asbestos cement. This range has a recessed courtyard elevation supported by thin iron posts, with a segmental-headed door to the right with boarded doors, a boarded door left of centre, and a replaced door to its left. The rear of the service range is of rubble stone with six camber-headed openings containing small-pane windows, except for the right-hand window which is boarded up.

The interior features a small entrance vestibule that leads into a double-height, top-lit great hall, which includes a balcony with neo-classical cast iron balusters. Similar balusters are found on the full-height open-well staircases behind the hall, with one staircase serving each wing. The great hall has a classical marble fireplace.
