Llanwensan Fawr Farmhouse

Llanwensan Fawr Farmhouse is a farmhouse with early origins. The most notable external feature from this early period is a semi-circular arched stone that serves as the lintel for a ground floor window. This stone displays branch-like radiations in relief and may have originally been part of a Norman door-head. The surrounding masonry is significantly battered at the base, with the batter interrupted by a later window that was previously a doorway, according to the Royal Commission on the Ancient and Historical Monuments of Wales (RCAHMW). The farmhouse has boulder footings and a roughly T-shaped plan, with the main range facing south and a stepped back wing to the east that has a modern extension nearby. The walls are roughcast rendered, with remnants of earlier lime render visible on the downhill gable end. The roof is slate with overhanging eaves and brick end stacks.

The building is two storeys high and features a three-window range of 4-pane casements, two of which have dormers. The ground floor has margin glazed sashes on either side of a yellow brick porch with a pointed arch, leading to a part glazed and panelled door with an overlight. At the right gable end, a wing is stepped back and down, showing signs of a former steeper roof pitch and indications of earlier building footings that may have extended outward. There are small cambered-headed openings with brick surrounds on the gable end. The wide rear cross wing has cambered-arched casements on each floor, and the side downhill elevation features 12-pane casements.

According to the RCAHMW plan, the interior layout consists of a hall at the downhill end and a parlour at the uphill end, separated by stairs. The interior is believed to retain an open fireplace in the hall, which has a low ceiling and a roof supported by arch-braced trusses, a tie beam, and three rows of purlins.
