Llennyrch is a substantial house of Snowdonian plan-type of c. 1600 with fireplace stair, former post-and-panel partition between entrance passage and outer rooms (moritices in the beam only now), and a rear kitchen wing. It was remodelled in the C19th when new partitions were created including an astonishing slate partition between parlour and service-room. There are collar-beam trusses I think but concealed by C19th ceilings. Acquired by the Woodland Trust in 2015. Noted RFS/RCAHMW/2015.
