Coed-y-Ffrnnon

Coed-y-Ffrnnon is a two-storey farmhouse built from local rubble that has been limewashed, topped with a modern slate roof. The building features 19th-century bargeboards on the main roofs and dormers. The original 16th-century block is aligned north-south and includes a porch on the east side. The north gable displays a projecting shouldered chimney with a tall square stack, while the south gable has a rectangular stone chimney. The porch is flanked by upper and lower windows on each side; the upper windows are located in 19th-century dormers, with a small pane vertical sash on the left and a horizontal sash on the right. On the ground floor, there is a vertical sash window on the left and a broad casement window on the right, along with a small ground floor window in the south gable. The central gabled porch has large windows on both floors, and the entrance on the south side features a segmental arch. The north side of the porch includes an unusual blind dormer that incorporates a chimney.

At right angles to the rear is a block dating from around 1700, which has a square stone chimney on the west gable. On the north elevation, there is a door set to the left, with a dormer window above a small pane ground floor window with a simple stone lintel to the right. At the rear, there are two first-floor windows set at the eaves (with the left window deepened) and two square ground floor windows with simple stone lintels.

The ground floor of the 16th-century block consists of four bays featuring stop-chamfered beams and joists. The beam to the right of the entrance has mortices for an in-and-out partition. Two beams on the north side have intermediate stops on the chamfers that form faceted lozenges. There is a massive lintel above the fireplace in the north wall. The two rooms to the left have relatively modern partitions. The roof of the 16th-century block has three collar-beam trusses and two tiers of purlins with cusped windbraces, which are ceiled at the level of the lower purlin. The cusped windbraces on both tiers of purlins likely indicate decorative treatment for the first-floor rooms rather than an open ground floor hall. On the south wall of the first floor, there is a complex plaster heraldic shield from the 16th century. The 18th-century block at the rear has a ground floor with a chamfered beam and joists, along with a large fireplace featuring a wooden lintel in the west wall.
