Gelli Gynan Farmhouse

This is a farmhouse, dating from the 17th century with later additions and alterations. It is constructed of whitewashed rubble stone with slate roofs and has a two-storey, L-shaped layout. The east front range features a 19th-century red brick stack centrally placed on the ridge, to the right of the entrance, and a smaller red brick stack at the right end. The left end of the roof is hipped. The long front elevation has a one-window range to the left of the entrance and a two-window range to the right; all windows are 20th-century replacements with six panes in hardwood frames. Stone sills are present, alongside cambered heads to the centre and left ground floor windows, and to the first floor left, with the remaining windows having flat timber lintels. A whitewashed gabled porch with a slate roof shelters the front door, which is a 20th-century replacement. The right end gable is rendered and windowless, while the left end wall forms part of a south-facing rear range which incorporates the oldest visible parts of the building, with no obvious structural joint between the east and south ranges.

The south side of the house has 20th-century windows matching those on the front elevation, within the end wall of the east range. The centre of the front has a two-window range with cambered heads, the upper windows slightly lower than the upper right window. A mixture of glazing is present, presumably serving service or storage rooms; specifically, a four-pane sash window on the first floor right, and casement window pairs on each floor to the left. A ledged door with a cambered head is situated to the left. The cambered heads of the windows are constructed with stone voussoirs.

The west end gable shows remnants of a substantial 17th-century four-light mullion-and-transom window, possibly reused, and a loft door above. The return side, facing towards the farm court, is joined to a listed north-facing farm range. A massive, central 17th-century external side-wall stack has a broad chimney breast and a tall, square stack. To the right, a slightly outshut section has a small-paned window on the ground floor and the remains of a 17th-century two-light stone-mullion window. Further on, within the attached farm building, are former outside steps leading to the house loft. A door gives access to the service range, which contains a datestone inscribed "16 TW 87", along with some heavy chamfered beams and oak joist floors. To the left of the stack, a further outshut section leans out, with a small 20th-century window to the right, a door, and a large, earlier 19th-century triple casement window with a cambered head to the left. The rear of the front range includes a small casement window pair on the first floor centre and a 20th-century lean-to porch on the left.
