Description

Cefn Coch is a 17th century gentry farmhouse featuring a three-window main range that is two storeys high with attics, and a lower two-storey single window range to the left (south). At the junction of the two ranges is a gabled porch wing. The exterior is rendered over stone, with slate roofs and exposed stone stacks at the gable ends. The main range is broadly symmetrical, with a shallow central gable topped by a chimney stack above the entrance. The entrance has a doorway flanked by narrow windows. The windows in the outer bays and the narrower window above the doorway have been replaced in earlier openings. The end-wall stacks are set diagonally, with the larger principal stack on the left-hand gable. The lower range to the left (south) features an enlarged or inserted window on the right (north) and a small window alongside it, both of which are modern. The two-storey gabled porch at the junction has an arched entrance on the ground floor and a small window above, also with modern detail. The rear elevation has scattered windows and a rear doorway to the main block. At the north end of the rear elevation, against the projecting stack, there is a gravestone for Thomas Meyrick, who died in 1763 and was a former owner of the house.

Inside, the main block has a central hallway with principal rooms leading off to the left and right, and an axial corridor at the rear leading to the south wing. There is a mid-17th century dog-leg staircase with turned balusters, a moulded handrail, and square newels topped with ball-finials. The staircase continues beyond a doorway as plain oak stairs leading up to the former servants' quarters in the attics, which feature a roof with pegged and collared hewn trusses. A hewn beam runs along the length of the ground floor rooms, although it is now covered. The south block is believed by the owners to retain the original inglenook fireplace, which is now enclosed. Throughout the house, there are shallow panelled doors.
