Cadw's description

In an isolated rural location within private grounds, set back from the E side a country road leading N off the B5111. The garage/coach house lies at the S side of an enclosed cobbled courtyard to the S of the house.

C19 threshing barn, contemporary with the adjacent stable range, built in 1836, and coach house, built in 1839 for Admiral Lloyd, the owner and occupier in the Tithe Apportionment of the time. The estate was a substantial holding of over 158 acres (64 hectares) which employed 7 servants in the house as well as labourers housed in the servants quarters, outbuildings and Upper and Lower Lodges.

Three bay threshing barn built of rubble masonry, the principal elevation facing the enclosed cobbled courtyard to the NW of dressed coursed stone with slightly advanced plinth and eaves course. Wide opposing doorways have shallow basket arched heads with slightly advanced keystone and chamfered jambs; flanking ventilation slits. Shallow pitched gable roof of large slates laid to diminishing courses.

A modern agricultural lean to addition has been built to the rear; with profiled roof on timber and metal uprights.

The roof has 2 king posts trusses, the floor could not be seen at the time of the survey.

Included as an exceptionally well-preserved C19 threshing barn which forms an important component part of the estate buildings at Plas Tregayan. Built to a coherent design along with the adjacent courtyard buildings and echoing the C19 character of the house for which they were built; together a reflection of the expanding fortunes of the estate at that time.
