Westabrook Farm and threshing barn

Westabrook Farm is a two-storey farmhouse with attached workshop and animal pens, originating in the 14th or 15th century, with substantial alterations in the 16th century and later periods, including 19th-century extensions and reroofing in the 1920s. A separate threshing barn of late 17th-century date stands approximately 20 metres to the south.

The farmhouse is constructed of granite block and rubble with rendered south elevation and a 20th-century pitched slate roof (originally thatched). The barn and ancillary buildings are also granite with corrugated iron roof coverings.

The farmhouse plan is rectangular, three bays east to west, and takes the form of an open hall house with a hall (now containing an inserted first floor), a solar wing, and a cross passage. A double-height workshop and animal pens are attached to the east, with single-storey lean-to extensions to the rear (north) of the house and workshop, and to the front (south) of the workshop.

The principal south-facing elevation has three window bays. On the first floor, the western window is corbelled at the head, marking the position of a guardrobe. The eastern bay is obscured by a 20th-century porch leading into a 19th-century extension on the workshop's south front. A disproportionate gap between the window heads and eaves marks the position of a raised roof. The west gable-end has a chimney stack, with a 17th-century extension to the flue visible on the west elevation, where earlier roof-height can also be traced in the stonework. A lateral stack (rendered) is centrally placed on the north elevation, below which is a single-storey 19th-century extension with pitched roof and 20th-century roof lights, with a further flat-roofed extension and lean-to. The east elevation of the house is tile-hung above the workshop roof. The workshop's east elevation has a high-level window opening with pigeon holes above.

Internally, the farmhouse is entered centrally on the south side into a cross passage with a granite screen to the east and a 19th-century timber door giving access to the workshop. To the west, the hall is screened from the passage by a 20th-century stud wall, with a 20th-century staircase to the north of the hall doorway. A bridging beam spanning north to south on the east side of the hall probably dates from the 17th century when the first floor was inserted. On the north wall of the hall is a 16th-century corbelled granite fireplace with a tapered hood rising in steps against the inside of the north wall, visible on the first-floor landing. Within the fireplace is a cloam oven, and to its right is a small lamp or candle shelf. To the right of this is a blocked square opening marking the position of a laver (for hand washing), infilled when the present staircase was inserted in the 1970s. Within a partially-revealed cobbled floor below is a slot marking the position of an earlier staircase. The remains of a 14th-century first-floor jetty can be seen at wall-plate level on the west wall. To the west of the hall is the chamber below the solar, with an alcove in the north-west corner marking the position of a 14th-century newel staircase. A 16th-century fireplace on the west wall was altered in the 19th century with a brick lintel below the granite lintel.

The 20th-century staircase leads to a small landing on the first floor, with a blocked early 17th-century window in the north wall. The upper level of the former hall contains mid-20th-century partitions and is divided north to south by a 14th-century open truss with smoke blackening at the apex. Above the south window is a reused timber thought to have come from a wind-brace in the 14th-century roof. The east wall is boarded up to the roof. To the west, the solar is partitioned from the former upper level of the hall by a 14th-century trussed and half-timbered screen rising from the jetty below. Although the roof was raised in the 20th century, historic slots for the rafters remain visible. The screen is punctured by a ceiling structure inserted in the mid-20th century and is wholly infilled with 19th-century lathe and plaster, but early peg-holes marking the position of a 14th-century window overlooking the hall remain. The solar is accessed at its north-east corner, opposite which is the stone tower of the newel mural stair. On the west wall is a hooded and corbelled fireplace (currently infilled) with a lamp shelf to its left. Adjacent to the window on the south wall, more apparent externally, is the position of a 14th-century guardrobe. Floors are concrete screed on the ground floor and 19th-century timber boards on the first floor. All windows are set within deep canted reveals with openings reduced to accommodate late 20th-century uPVC casements. Single-storey extensions to the north of the house date to the 19th century and are of little architectural or historic interest.

The workshop (or attached barn) is accessed internally through double-doors from the cross passage and externally from the south through a 19th-century single-storey lean-to. Roughly square in plan and double-height, it has a timber mezzanine floor across its west side reaching the position of the removed 14th-century external east wall, which retains its cruck-beam scars; the space was extended in the 16th century. The south wall has been rebuilt several times, and a high-level window on the east wall has reused granite-block jambs. A small covered yard is on the north side of the workshop. Attached to the east side is a single-storey animal pen with timber cross beams and a curved wall at the north-east corner. The base of the east wall contains substantial earth-fast granite boulders.

The threshing barn is a double-height structure of granite rubble construction with an 18th-century half-hipped collared-truss frame replacing a late 17th-century thatched roof. The north and south openings (out and in respectively) have timber ledge and brace double-doors within altered openings. A further double-height double-door opens on the west elevation. Timber single-storey lean-to structures on the north elevation probably date to the late 19th century and show timber marks typical of Baltic imports.
