Description

Pen-y-Maes is a two-storey building with a two-window painted roughcast front, topped by a slate roof and rendered chimney stacks. The windows are offset to the left and feature gables on the first floor, with architraves surrounding unhorned four-pane sash windows. Below, there are splayed bays with similar glazing flanking a panelled door that is sheltered by a pitched and trellised porch. To the right, there is a narrow buttery window. The gable end on the right has a horned four-pane sash window and a boulder plinth. This side curves back towards the rear, following the road's line, and the roof slopes down over a single-storey and attic lean-to, which includes a small sash window facing the road. A modern lean-to fills the space between this structure and the rear courtyard boundary wall, which is accessed by a boarded door. At the centre of the rear, there is a four-pane window above a date stone, and to the right, a squared bay with a boarded gable and horned tripartite sash glazing, along with a modern flat roof extension below.

A rubble wall borders the front garden from the hill and features a doorway with a vermiculated stone surround. The building's earlier origins are visible in the right-hand room, where the former gable end wall can be seen. There are two small service rooms from different periods, and the building includes 19th-century stairs.
