Hafan Deg forms one of a Mid-C19 pair of cottage built in the simple 'vernacular revival' style particularly favoured by the Penrhyn Estate for its workers. They were probably built by the Penrhyn Estate as part of Edward Douglas-Pennant's considerable efforts to improve the estate, to which he had succeeded in 1840.
