Trebisken House

Trebisken House is a farmhouse, now a house, likely built around 1700, with an outshut added in the mid 18th century and some 20th-century alterations. The building is constructed of painted stone rubble with brick dressings, and the outshut is made of stone rubble and cob. It has a bitumenised slate roof with ridge tiles, including some surviving handmade crested ridge tiles, and features gable ends. There is a gable end stack with brick shafts, one of which was rebuilt in the 20th century.

The layout consists of a two-room plan, with a large kitchen on the left, a passage, and a smaller parlour on the right, each room heated by a gable end stack. The outshut runs along the entire rear and is single-storey with a loft; it includes a heated room on the left with a stack at the left end and an unheated room on the right that contains an oven. A straight stair was added in the rear of the passage in the 19th century, and a partition wall on the left side of the passage was removed in the 20th century.

The exterior is two storeys high and nearly symmetrical with a three-window front. The ground floor features a 20th-century gabled porch with glazed double doors, a late 19th-century four-pane sash window on the right with a cambered brick arch, and a 20th-century two-light six-pane casement window on the left, also with a cambered brick arch. The first floor has three 20th-century two-light casements with six panes, eight panes, and six panes. The left end of the building is blind, showing a straight joint in the masonry where it connects to the outshut, while the right end is also blind. The rear has a variety of casements, including a first-floor two-light nine-pane and six-pane casement, a two-light four-pane casement, a single casement, and a six-pane casement. The ground floor features a 19th-century two-light eight-pane casement, a 20th-century door, and a two-light four-pane casement with a timber lintel. To the left, there is a later outshut behind the parlour with a door, and a 20th-century glazed conservatory.

Inside, the ground floor room on the left has a large fireplace with a roughly hewn chamfered timber lintel and a cloam oven to the rear left, along with 19th-century ceiling beams.
