Cadw's description

Set back below the SW side of the A487(T) by the junction with the road leading into the village of Gellilydan. The outhouse is located directly to NE of the house at Tafarn-helyg.

Late C18 or early C19 outhouse, probably contemporary with the adjacent house at Tafarn Helyg and formerly used as a forge.

Single storey outbuilding, originally in use as a forge. Built of rubble masonry including large boulders; slate roof with stone gable stack to R (SE) gable with dripstones and capping. The principal elevation faces the house to SW and has a boarded stable door to L, 2-light casement window to R; single window in NW gable.

The interior was not inspected at the time of the survey (June/July 2003). Said by owner to retain original forge fittings.

Included as a little altered outbuilding that forms a group with the adjacent house and outhouse at Tafarn Helyg.
