Langstone Court was built c.1700 by the Guillym family. A five-bay house, it is noted for its panelled rooms with plaster ceilings. At the front of the house is a grassed court d'honneur, surrounded by a wrought-iron screen with gates and piers. A stable block lies to the N. To the S, an iron gate gives access to an orchard and flower garden. The garden is terraced. A park is first shown on maps in the late 19th century, when it is a modest, crescent-shaped affair at the front of the house. There are some mature native trees and some specimen exotics. An avenue has been planted along the Llangarron lane. The park features a stone structure of unknown function - the park is not large enough to need a viewing platform, and in any case such features tend to be of 17th century date. (3)
