Felin-hafodwen

Felin-hafodwen is a 19th-century rubble-built structure with a slate roof. The original rectangular building was extended to the south and west around 1880, bringing the western gable close to the road. It is set into rising ground, with a central door on the north side that leads to the first floor. To the right of this door, in the added section, is a divided boarded door approached by stone steps, with a dormer gable above the doorway. The west end features a long roof slope to the right, a large four-pane window on the first floor with a timber lintel and slate sill, and a two-light twelve-pane casement window to the right with a similar head and sill.

On the ground floor, there is a boarded door to the left with a cambered brick head, a twelve-pane casement window in the center with a brick head, and another boarded door to the right with a cambered yellow brick head. The eastern end retains a cast-iron overshot waterwheel made by Jones at the Priory Foundry in Carmarthen, along with a cast-concrete launder. A large window in the gable has a timber lintel. The wheel was powered by a leat supplied from a pond above, although this system is mostly obsolete now.

The south side has an added lean-to portion from around 1880 that occupies most of its length, featuring a 20th-century first floor window and a small four-pane ground floor window. There is an open lean-to to the right at the angle between the addition and the original structure, which has a six-pane window on the first floor.

Most of the machinery inside is intact and represents the primitive pre-spur-wheel "Vitruvian" type, where the pit wheel drives the single stone nut directly. It includes an iron pit wheel with wooden teeth, a cast-iron stone nut with cast-on lugs for lifting it out of gear by a missing windlass under the hurst, and surviving chains of an oat-sieve. The setup also features a horse-frame and hopper with a single pair of stones, and a large worn detached grindstone on the first floor. The late 19th-century extensions provided a drying room to the west, along with a rubble kiln-opening and a primitive part-loft above.

The building is deteriorating in parts, particularly on the west side, as noted in January 1996.
