Pen-Y-Lan Hall

Pen-Y-Lan Hall is a building designed in the Tudor-Gothic Revival style, featuring a stuccoed and castellated exterior. The main entrance elevation is two storeys high with an attic behind a parapet. A moulded string course runs along the first floor, and there are symmetrically placed castellated stacks at each end. On the right side, there are two bays at ground floor level, each with two cusped windows that have hoodmoulds, and the first floor also features two cusped windows with hoodmoulds. A two-storey projecting porch, which is crenellated and two bays wide, has a bay on the right that is set slightly back. The pointed arch doorway, complete with a hoodmould, leads to a wooden door, and to the right is a three-light cusped window with a hoodmould. The first floor has three two-light cusped windows, all with hoodmoulds.

The left-hand elevation is two storeys with an attic behind a castellated parapet and is five bays wide, flanked at either end by the return of castellated stacks. The ground floor features long windows with hoodmoulds, while the first floor has 12-pane sash windows, also with hoodmoulds. The rear elevation is two storeys with an attic behind a parapet and is four bays wide, featuring three castellated stacks. The ground floor includes one long window with a hoodmould and a large canted bay window, while the first floor has 12-pane sash windows with hoodmoulds.

Inside, the main staircase hall showcases a mid to late 19th-century Tudor-Gothic Revival design, featuring some stained glass with heraldic motifs, panelling, and a wooden staircase. There are several marble fireplaces, including a black marble fireplace with cusped details that likely dates from the 1830s. The attics contain sliding sash windows, and there are brick barrel vaulted cellars.
