Y Coed including attached former byre

Y Coed is a two-storey farmhouse with a lower former byre, generally constructed of random rubble sandstone and topped with a slate roof, although the byre roof has been recently renewed. The house features a three-window front from the 19th century made of coursed rubble, with larger quoins and stone lintels and sills. To the right, there is a 17th-century stone stack, while a 19th-century stone stack is located to the left. The upper storey contains 9-pane hornless sash windows on the left and right, with a similar window on the lower left and a later horned sash window on the lower right. A boarded lean-to porch with boarded doors is situated at the extreme right. The left gable end has an infilled former doorway on the upper right and an inserted attic window on the upper left. The rear elevation has three windows with late 19th-century casements and an added lean-to on the left.

The byre, which is lower and built on a sloping site, features a wide cross passage doorway to the left under a timber lintel. Immediately to the right of this doorway is a recently inserted door in place of a window. To the left of centre is a modern window in an earlier opening, and to the right of centre is a boarded stable door under a timber lintel. Further to the right is a similar stable door with a modern window to its right in a 19th-century opening. There is a loft opening to the left of centre that has a replaced window. The right gable end has an added lean-to at a low level, below the yard in front. In the lower storey, there is a 17th-century window with a timber surround, above which is a loft window with diamond mullions, of which two out of four survive. The rear of the byre has a lean-to kitchen clad in corrugated iron sheets.

The only remaining feature of the original long house is a single cruck truss, which has been later incorporated into the cross passage wall. This truss includes a collar beam and stands on timber sills above floor level. Inside the hall, there is a post-and-panel partition that contains a doorway to the parlour, featuring a segmental pointed head and an original boarded door with strap hinges. The partition also remains between the parlour and the dairy, which has a single salting slab and a flagstone floor. A fireplace stair includes an original ledged and battened door from the hall.
