Bossiney Court and Outbuilding Adjoining on North West

Bossiney Court and an adjoining outbuilding date from around the mid-17th century and are now divided into two houses. The building is constructed of local slate-stone rubble, with a slate roof featuring gable ends and a hipped end to the central two-storey porch. Brick end stacks are present. A lower slate roof with a hipped end covers the outbuilding on the left-hand gable.

The interior has undergone considerable remodelling in the 19th century and late 20th century, obscuring the original layout. It likely originally comprised a two-room plan with a cross or through passage, and a central two-storey porch. An outbuilding was added in the early 19th century to the left-hand gable end, and a single-storey outshot was added in the late 19th century to the right-hand gable end. Rear outshots to the main range were probably added in the early 19th century and subsequently remodelled in the late 20th century. It may have originally been larger and served as the manor house for the Borough Manor of Bossiney.

The front of the house is symmetrical, with three windows on each floor. Dressed slate-stone arches with keystones frame the renewed 20th-century 12 and 16-pane horned sash windows. A straight joint in the masonry is visible near the right-hand gable. The central two-storey porch has a hipped end, a chamfered granite entrance with a flat lintel and diagonal cut stops to the jambs, and a 20th-century glazed door. A slate string is positioned above the ground floor, and an escutcheon sits above the entrance. The first floor features a 12-pane sash window. The two-storey outbuilding on the left-hand gable end displays 20th-century fenestration. A single-storey outshot is present on the right-hand gable end.

Inside, the left-hand room contains a circa 17th-century oak chimney-piece, partly reworked in the 19th century. The overmantle is reported to have been lost in a fire. The chimney-piece jambs are fluted and carved with a floral motif; the lintel features an escutcheon with a Duchy crest on the left and a castle (the insignia of the Borough seal) carved in relief on the right. On the first floor, a circa late 18th-century segmental arch with fluted pilasters spans the wide opening from the central bedroom into the room over the porch. The right-hand side of the house was not inspected.

The Borough of Bossiney received a charter from Richard, Earl of Cornwall, possibly around 1253. Sir Francis Drake represented the borough in the Parliament of 1583. By 1831, the number of eligible voters had reduced to ten despite the borough returning two Members of Parliament, leading to its placement on Schedule A of the 1832 Reform Bill and subsequent loss of its parliamentary privileges.
