A rectangular long hut, 7.5m northwest-southeast by 6m. It was defined by grass-covered stones set in a sunken hollow. The hollow was in the southeast corner of a field that appears to have been added to the field systems east of Pentre Dolau Honddu after the time of the 1840 Merthyr Cynog parish tithe map, so the field is probably not associated with the long hut.
