Trevince House

Trevince House is a country house situated on the site of an earlier manor house. The house was largely rebuilt and remodelled around 1870, although it incorporates elements dating back to the 17th, 18th, and early 19th centuries. The construction utilizes various walling materials, including granite ashlar on the south side, squared killas brought to course with granite dressings on the west side, and killas rubble with granite quoins, jambstones, sills, and lintels on the east side. The roofs are hipped to the south and east, with gable ends to the north, covered in dry Delabole slate, and with a grouted scantle slate roof over the east wing. Axial and gable brick chimneys are also present.

The house has a complicated, irregular plan, possibly built around an earlier core, with a two-room double-depth farmhouse wing to the right (east). A single room from the early 19th century, originally a two-room house, projects forward to the left of the middle section (south). A later room is situated in the angle between this and the east wing. Around 1870, the house was extended to the far left with a three-room garden front range built at right angles, facing west, along with rear service rooms.

The house is two storeys high, with an attic in the later additions. The south front is irregular, with a canted three-window bay from around 1870 on the left, adjoining a two-window ashlar front, likely surviving from a former five-window front of the early 19th century. A later or remodelled two-window rendered front is located to the right, slightly recessed, and in the angle between the main part of the house and the earlier 19th-century three-window south front of the east wing. The south and west fronts of the main house primarily feature horned four-pane sashes, with two courses of dentil-like bricks to the eaves. Louvered shutters are present to the southwest ground floor rooms, and French windows with marginal glazing, progressing to arched overlights, are found in the ground floor openings of the ashlar front. A roof dormer over the middle section has a gable pediment. The south front of the east wing retains original hornless sixteen-pane sashes with lintels incised to resemble voussoirs.

The west four-window entrance front has a tetrastyle granite Tuscan porch to the entrance in the second opening from the left. The porch features a granite plinth, a mid-floor string, and voussoirs to shallow arches. Four roof dormers with gable pediments and horned six-pane sashes are present. The interior was not inspected but is said to feature a fine stair hall and some panelled rooms. One of the farmbuildings is topped with a clock.
