Much of the enclosure here had been removed by later ploughing. A short undamaged section of bank and internal ditch survives and suggests that the enclosure once encompassed an area to the south of Nant Criafolen, within which two buildings 3m apart were situated.

Excavation of the buildings revealed a more complex structural sequence than seen over the rest of the hafod site (NPRN 409468). Not only had a later prehistoric roundhouse (NPRN 409469) stood on the site, but one of the two rectangular houses had been radically altered. The eastern hut measuring 7.5m x 4m had been badly damaged by ploughing but also earlier robbing. Its hearth remained, composed of two gritstone slabs and several smaller edge-set stones, set at the centre of the west wall. The western hut originally measured 6m x 4m but had been enlarged at its east end to 12m x 4m with an entrance located in the centre of the north wall; it is thought that this building would have been partitioned. Within the building was a beaten earth floor, at the centre of which stood the hearth, a stone bench had also been constructed against the south wall. A series of postholes and water gullies were excavated outside both huts and a midden was located to the north of the west building, refuse in the form of pot-sherds and objects of metal and stone provided good dating evidence which indicates occupation here in the 15th or 16th century.
