Description
The Old Post Office and Llyswen is a building constructed from whitewashed rubble stone with slate roofs and features three stacks, including a rendered brick stack at the left end shared with Ty Mawr. The Old Post Office is two stories high and has a three-window range, with timber cross-windows that include stone voussoirs and keystones. The central half-glazed door has a similar stone head. On the ground floor to the left, there is a notable 19th-century shop front consisting of a door with an overlight, aligned with a window above, and a window to the left featuring nine large panes. An iron railing is positioned in front of this window. The rear of the building has a projection to the left, with a central door and a four-pane window above it, as well as a lean-to on the right. Llyswen, adjacent to the Old Post Office, has grey washed walls, similar voussoirs and keystones above the door to the right, and a one-window range with five-pane horned sashes to the left. The rear includes a two-story lean-to addition made of brick.
