Tylcha Wen including attached range of former outbuildings

Tylcha Wen is a one-and-a-half-storey house with an attached long farm range to the west, built of rubble stone with rendered finish under slate roofs. The house contains two windows on the front elevation, with the entrance door positioned to the far right and a window to the left. The windows above are aligned and rise to the eaves, set in wooden surrounds with dripmoulds to the lower storey openings. All fenestration contains late 20th-century wooden glazing, including the door. A large rendered ridge stack stands between the house and farm range, originally positioned behind the porch, with a smaller rendered stack at the east end.

The front wall shows a bulge to the left of the house marking the position of the former porch. The farm range front wall is highly irregular, revealing signs of historic alterations. To the right of the bulge is a ventilation slit, and to the left is a multi-pane metal casement window set with stone lintel and sill, probably an original opening. A small opening to the loft sits above. Immediately to the left is a planked door with flat head.

The cow house projects slightly from the house and stable with a lower roof line. To its right is a low planked door with timber lintel. To the left are the remains of a dripstone, and further left a window with segmental head and brick surround containing a multi-pane metal casement, probably originally a door. Above is a 20th-century window infilling a larger opening with a dripstone. At the far left is a blocked door opening retaining part of a dripstone, with a slight buttress at the angle. The west gable end stands on substantial stone foundations and has a dove hole in the apex with projecting stone lintel and sill.

To the rear, the former cow house has a planked door to the centre with timber lintel and part of a dripstone, with the roof pitch covered in corrugated iron. Behind the stable is a planked loft opening with stone sill, possibly an original window, with a blocked doorway offset below to the right featuring a segmental voussoir head. A gabled rear wing extends from the house with shallow roof and ridge stack. A small 20th-century porch and kitchen lean-to attach at the north end with a door to the east, and a small lean-to stands against the west side. Windows are in the same style as the front. An upper storey window to the gable has a dripmould, and a blocked opening with similar dripmould sits to the left. The east side contains a window to each storey, with another above the west lean-to. Behind the main range, left of the wing, is a late 20th-century window.

Inside, the front door opens into a hall partitioned at the east end to form a narrow stair hall with straight stairs leading to the attic storey. The hall features deep chamfered cross beams with cut stops and fillets. The west wall contains a 20th-century stone fireplace surround, to the right of which are stone fireplace stairs now blocked off. To the left was a doorway into the stable (originally the kitchen of the house), also blocked. The rear wing, formerly the dairy, is modernised but retains original roof trusses upstairs with a corridor along the north side.

The stable and cow house are now used for storage. The stable, originally the kitchen, retains deeply chamfered cross beams as in the hall, with a doorway featuring a chamfered Tudor-arched head leading into the cow house. The attic above the stable, originally an upper chamber, is said to retain its original timber work.
