Description

Pen-y-Bont, formerly known as the Penrhyn Arms Inn, is a large three-storey building constructed from random rubble, dating back to the 19th century. It features a medium-pitched slate roof and is connected to the adjacent Pen-y-Bont farmhouse. The building has a shared stone chimney on the right, which has a simple cornice and weathercoursing, and a small, simple brick end chimney on the left.

The entrance is located on the left and is accessed through a late 19th-century porch made of slate slabs, which has a plain wooden bargeboard and a segmental opening. The door is part-glazed and includes a narrow three-pane vertical window on the right. The ground and first floors have recessed 16-pane unhorned sash windows, which feature projecting slate cills and cambered red brick heads; the first-floor heads are one header deep, while the ground-floor heads are double. The third floor has square 12-pane sashes located under the eaves.

The rear facade is symmetrical, with a central boarded door flanked by six-pane sash windows on the ground floor. The upper floors have 12-pane casements, with the upper ones being taller and, like the ground-floor openings, featuring dressed slate lintels. There is a large ground-floor window with modern glazing on the south-facing gable.

At the time of the survey in November 1996, the building was not inspected but was being used as office space.
