Llanfair-fach House

Llanfair-fach lies to the north-west of Cardiff, near to the hamlet of Capel Llaniltern in the community of St Fagans. The house dates from the early 17th century. In 1670 it was recorded as a "tenement in the parish of St Fagan". The Royal Commission on the Ancient and Historical Monuments of Wales undertook an internal survey in 1995, and holds a large collection of photographs taken at that time in its Coflein archive.

The building is of two storeys and built to a cross-passage plan. The construction material is local rubble under a Welsh slate roof. The architectural historian John Newman, in his Glamorgan volume of the Buildings of Wales, noted the "status-giving porch". Peter Smith, in his study, Houses of the Welsh Countryside, records that access to the upper-floor was by way of a staircase next to the hall fireplace. Cadw lists the house at Grade II* as "an important gentry house with much surviving detail".
