The grassy platform measures 6.5m (E-W) by 3.5m, cut back to 1.5m deep and built out to 1.3m high.
The platformed area has been extended to the north with material dumped around the north, west and east sides to bound a sloping enclosed area measuring 7m (NE-SW) by 6m within a stony bank 1m-1.5m wide and 0.3m high. This `paddock? lies just below the building platform. The enclosure entrance was probably in the NE corner where the bank is lowest.
This is part of a larger group of features, mostly platforms, strung out along a steep SE-facing slope below the ridge of Cefn Cul at around 360m above OD (NPRN 409251).
