This long hut is one component of a group of structures which forms a deserted rural settlement on Llain Wen (NPRN 418534).
It is a two-bay structure with long axis aligned with the contours. It is defined by spread rubble walls of large stones and small boulders, 1m+ wide and 0.6m high. It measures internally 6.2m long (NE-SW) and 3m wide. A narrow partition wall lies about 2.4m from the south end. No obvious entrance is visible.
