Derives its name as a former monastic grange to the nearby Abbey at Parc Grace Dieu. At the Dissolution, the grange was granted to Sir Thomas Herbert of Wonastow, Monmouthshire and William Brett. Although the present Renaissance farmhouse is largely early C18 in character, the basement contains C17 sunk chamfer mullion windows, suggesting that an earlier house may have been rebuilt on the site. In the C19 the external fenestration was changed and sash windows, some with marginal glazing bars, inserted. The present house was probably built by the Grayhurst family, silversmiths of the Strand, London, who owned the house in C18.
The attached cowhouse (bounding the E side of the lower yard) dates from the early C19.
