One of two house platforms (the southernmost) located on ground falling away to the west, and part of a larger grouping on Mynydd Machen (NPRN 15507). The platform terrace measures 13m east by west by 6.5m, is cut back 1m deep and built out 1.3m high. A slight inner scarp is visible on the lip despite overgrowth of heather and mosses.
Some damage has been caused by footpath/vehicle erosion.
