Upper Red House, Llanvihangel-Ystern-Llewern, Monmouthshire, Wales, is a farmhouse of the late 17th century. Standing one kilometre south west of the parish church, the building is little altered from the time of its construction, although subject to restoration in the 20th/21st centuries, and has a Grade II* listing.
The architectural historian John Newman, in his Gwent/Monmouthshire volume of the Pevsner Buildings of Wales series, notes the house has two storeys and three bays, under a hipped roof. The style is "Renaissance", with a centrally positioned chimney stack, which was "rare" in Monmouthshire. The building is of English bond brick, which has been colour washed red. It is listed at Grade II* by Cadw. The Royal Commission on the Ancient and Historical Monuments of Wales (RCAHMW) holds an extensive photographic archive of the house. The house remains a private home, offering bed and breakfast accommodation.[1]
