Ty'n-llwyn Farmhouse

Ty'n-llwyn Farmhouse is a one-and-a-half storey, L-shaped house dating from the 18th century, constructed of whitewashed rubble stone with slate roofs and stone stacks. The house has group value from its contribution to the rural landscape. The main range faces west and features a panelled front door positioned to the right, near the angle of the ranges. A small catslide porch shelters the door. To the left of the door is a datestone inscribed "PDS 1762," and further to the left, a small window that previously lit a pantry. A wide planked door with a timber lintel provides access to a north unit, left of which is an early two-light casement window. A gabled dormer containing a casement window sits above this door and window, with a projecting stone stack at the north gable end. The west unit, set at right angles, has higher eaves, a casement window to the lower storey, and a gabled half-dormer above. A stone end stack is also present. An added cart shed, with a corrugated steel roof is positioned to the right of the west unit – a wide opening with a timber lintel is present at its west end.

The rear elevation has a gabled chimney projection to the left, extending above the hall fireplace. The roofline is continuous with the added west unit of the house, suggesting contemporaneous construction. To the right and set back is a doorway into the former hall, possibly a later addition, with a small brick porch featuring a hipped slate roof. A late 20th century casement window and a gabled dormer are centrally placed on the rear elevation. To the right again is a small gabled bay with a short end stack, serving as a wash room. The south side has similar 20th century casements and two gabled dormers.

Adjoining the north end of the main range, at an angle, is a long, low range containing three pig sties and a former smithy to the right. This range is built of whitewashed rubble stone and has a corrugated asbestos-cement roof. Each pig sty has a stable door on the right, a two-light opening with shutters on the left, and a small chute below for dispensing swill. A wide opening provides access to the smithy.

The main range is a three-unit design with the hall located at the right end. A small lobby is accessed from the front entrance, leading to the hall, which is separated from the rest of the living space by an archway. The hall ceiling features a deeply chamfered cross beam with run-out stops. A large fireplace with a wide segmental arch is positioned at the rear of the hall – the original lintel may be behind the plaster. A wooden staircase is situated opposite the entrance, in the southwest corner, with small turned balusters and a cellar beneath. A doorway to the north leads to the kitchen, which occupies the central unit. A further room is located to the west of the hall, within the later unit, and is currently inaccessible. The external doorway to the north of the main range leads into a room that is not currently inhabited but was formerly a wash room; it has a large fireplace with a chamfered timber lintel and a small projection to the rear. A flight of wooden stairs to the right leads to an attic room, where a cruck-framed partition is visible. The bases of the crucks were not visible, and the partition has substantial timber posts beneath the crucks.

The cart shed includes a substantial truss with raked struts and an external stack on the rear wall of the west unit. The smithy, attached to the pig sties, has a small fireplace against the north end stack of the main house.
