Description
Westport House is a house dating largely from the late 16th century, with alterations and extensions added in the mid-18th century and a library built in the mid-19th century. The exterior is rendered over limestone rubble, with overlapping boarding to the library, brick gable and axial stacks, and a stone slate roof. The plan is of a single-depth form, now with a rear extension. The house has two storeys and an attic and features a 2:3:2-window arrangement. A central three-window 16th-century house has a door on the right-hand side, with 18th-century extensions on either end. The left-hand extension has a doorway and 6/6-pane sashes in exposed boxes. French windows are present in a single-storey early 20th-century addition (a former studio) attached to the right-hand end. Internally, details include steep collared trusses from an earlier roof, extended in the 18th century; a good 16th-century unglazed oak window with diamond mullions, now an internal opening; a well-preserved early 18th-century panelled ground-floor room with egg and dart moulding; a winder stair leading to the attic; and an 18th-century rear stair flight. The former studio has a segmental-vaulted timber ceiling and panelled walls.
