Pen-y-Llan House

Pen-y-Llan House is a two-storey brick building with a slate roof, featuring a two-window range and an entrance slightly to the left of centre. The entrance consists of a six-panelled door with an overlight, set in a renewed pedimented case. On each floor, there are flanking windows that are 12-pane sashes with fine glazing bars and painted flat-arched stone heads. An oriel window is located on the first floor in the right-hand gable return. The building has coped gables with end wall stacks.

Adjacent to the house is a shop building, which may be a slightly later addition and is set forward of the house. This shop building is also two-storeys with a single window range. The ground floor is entirely occupied by a shop front that features a doorway recessed to the left and a window divided by two slim mullions, beneath a continuous fascia. Above this, there is a four-pane sash window with a painted flat-arched head. The shop building has a hipped slate roof.
