Description

Trawsnant is a storeyed farmhouse built of rubble, sitting partly on boulder foundations, and topped with a slate roof featuring a brick parapet. It has a squat chimney from the late 19th century, which includes weathercoursing and a cornice. The plain entrance is located to the left and has a 19th-century slate lintel above an original opening with a boarded door. To the right, there is a 19th-century 12-pane casement window, also in an original opening. There is a reduced bay to the left, which is flush and has a corrugated asbestos roof, along with characteristic long quoins at the corner. Adjoining the right gable is a 19th-century lean-to with a slated roof and an open entrance, featuring a lintel similar to the others.

Inside, the main room, which was formerly the hall, has a beamed ceiling with a wide chamfered transverse beam and finely stopped-chamfered joists, although a quarter of the ceiling has been removed. There is a wide inglenook fireplace with a stopped-chamfered bressummer and a 19th-century bracketed mantelshelf, along with a 19th-century cast-iron range. To the right of the fireplace, there is a primary 'salt cupboard' niche with a contemporary pegged oak surround. To the left of the fireplace, the original stone corkscrew stair leads to the first floor, with its lower steps slightly projecting into the room. There are blocked primary windows in the stair (on the gable end) and the rear wall, both of which are small. The floor is covered with 19th-century Buckly tiles. Unusually, there is a similar but smaller primary fireplace on the first floor. The roof features a chamfered collar truss with a two-bay structure, along with modern purlins and rafters.
