Nantybanw, Llantrisant

Nantybanw has a datestone of 1625[1] and was long-thought to have been constructed entirely in that mid-17th century period. Recent research shows a more confused genesis. RCAHMW suggests that a reconstruction c.1600 of an earlier house, was continued by the addition of extensions dating from 1625.[2] The house was reconstructed in the 19th century and fully restored in the 20th. This restoration saw the inclusion of doors and doorcases from a demolished house, Graig Olway, Llangeview, and the insertion of a new staircase modelled on that at Upper Dyffryn House, Grosmont.[1] Nantybanw remains a private residence.

The house is of two storeys, with attics, and is constructed to a T-plan. It is built of whitewashed rubble.[2] The architectural historian John Newman, notes the "typical but not especially rich timber fittings" of the interior.[1] Peter Smith records the house as possessing examples of the "typical Welsh ornate doorheads" in his work Houses of the Welsh Countryside.[3] The house is listed Grade II*, its listing record describing it as "an important early 17th century house (with a) great deal of surviving original detail".[2] The associated barn range,[4] cider barn[5] and mill house have their own, Grade II, listings.[6]
