Talwrnmaenog Farmhouse

Talwrnmaenog Farmhouse is a one-and-a-half-storey house built of rubble stone, situated on a sloping hillside. The roof is covered with slate and features a brick ridge stack that replaced the original hall stack, along with a 19th-century stone stack at the right end. To the right of center, there is a one-and-a-half storey porch that was rebuilt in the early 20th century, which includes a pointed arched doorway and a window above it, both set under a concrete lintel. To the left of the porch, there is an enlarged hall window also under a concrete lintel, and further to the left, the kitchen is illuminated by a late 19th-century casement window beneath a wooden lintel. A recently added window is located at the left end of the house. To the right of the porch, the parlour is lit by a late 19th-century sash window under a wooden lintel. The attic features three gabled roof dormers, each with sash windows.

On the right gable end, there is a small window at the lower right and a smaller upper right opening with a shutter, both equipped with drip moulds. The rear of the house is pebble-dashed and painted cream. On the left side, there is an inserted boarded door with a small window to its right. To the right of center, there is a shallow projection, possibly from a former stair turret, beyond which is an added blockwork lean-to with a casement window at the right end. A blockwork lean-to has also been added to the left gable end.

Inside, the porch leads into a passage that conceals a post-and-panel screen. There are two doorways with shaped heads; the more ornate one leads to the hall, while the simpler one opens to a passage adjacent to the hall. The original extent of the hall is still visible through the cross and spine beams, which span only two-thirds of the room's width, allowing space for a passage on the entrance side. The cross beams feature stop-chamfers. The hall and kitchen have back-to-back fireplaces. The current passage between the hall and kitchen, located at the rear of the house, likely corresponds to the original stair location, indicated by a slight projection in the outer wall. The present stair is modern. The parlour, which has been divided into two rooms, contains a fireplace with a timber lintel and stepped stops.
