Penamen House

Penamen House is a 1.5-storey building with a three-window front, constructed from coursed rubble masonry with red sandstone dressings. It features a moderately pitched red tile roof with oversailing eaves, deep verges, exposed purlins, and bargeboards. The house has rubble stacks, with a lateral stack at the rear and water tabling.

The front elevation includes three gabled stone dormers, the central one being broader. Each dormer has deep verges, bargeboards, and apex vents. The central section features paired two-light stone mullioned windows with iron lights made by Monks of Chester, while the flanking dormers have similar three-light windows. To the right of the center, there is a glazed timber porch with a gabled roof and half-timbered gable above half-glazed double doors, set on a stone plinth. Inside the porch, there are glazed and panelled inner double doors with stained and coloured glass. The left side has paired two-light windows, with a three-light mullioned window to the right and two-light windows to the extreme left, all with plain labels. The right gable end elevation is rendered.

At the rear, there is a lateral chimney in the center, with a dormer to the left and a two-light mullioned window. A small gabled stone dormer, set wholly in the roof, has deep verges and a two-light mullioned window with tile-hung cheeks. An advanced gabled bay to the right features a two-light window, while the ground floor left has a three-light window with similar detailing. A modern lean-to conservatory largely conceals the ground floor. A service wing adjoins at right angles to the right, featuring a gabled stone dormer with a three-light mullioned window. There is a lateral stack to the right with a modern cut window below, and a two-light window in the gable end, similar to the ground floor left door to the right, which has a stone surround. Stone mullioned dormer windows are present on the east elevation, with a two-light window on the north gable end and a ground floor window to the right.

Inside, the house retains ogee stop-chamfered transverse ceiling beams, with similar detailing on the bressumer of the lateral fireplace. An early 18th-century staircase features cannon barrel balusters with bulbous bases, a toad's back handrail, and square newels. The interior also includes good late 19th-century fittings such as doors and cornices. There are three early 18th-century doors on the first floor with 19th-century architraves. The master bedroom has a plastered four-segmented Gothic "vault," and the roof timbers are said to have trefoil cusping.
