Trehill

Trehill is a house dating to approximately the late 16th century, with significant alterations and additions in the 17th century. It is constructed of stone rubble with an asbestos slate roof, featuring gable ends. The rear wing on the southwest and the lower end on the northwest (left) have a lower roofline, while the roof above the hall and inner room was raised on the southeast (right) at some point. The building has rubble stacks in the gable ends, with brick, stone rubble, and stone/brick combinations as shafts. The original plan has been considerably altered and probably re-oriented, resulting in a 'T' shape. The southwest rear wing may be part of an earlier range, featuring a late 16th or early 17th century doorcase, which was the probable original entrance. A partly blocked opening on the southeast side remains as evidence of a former through passage. The northeast end was likely rebuilt in the early 17th century and extended with a three-room range and cross passage leading to the rear wing. The room to the northwest of the cross passage became a service room, containing an end stack. The hall stack and fireplace have been removed.

The north-east front has two storeys, with the left-hand range taller than the right. It features an asymmetrical facade with three windows. The left-hand range has four large stone rubble buttresses. The first floor windows include two 20th-century casements with glazing bars. The right-hand range has a 20th-century stone rubble and glazed porch on the left, extending forward to connect with a 20th-century garage. A 2-light casement with a timber lintel and slate hood is to the right of the porch, and above it, a 20th-century 2-light casement sits on the first floor. Single-light casements are present in the gable end on the northwest, on both ground and first floors. A projecting wing extends to the southwest at the rear, and a 20th-century kitchen extension connects to the northwest. A 20th-century glazed door is in the gable end. On the southeast side, a 20th-century window is set within a partly blocked earlier opening with granite, chamfered jambs.

Internally, the left-hand range’s ground floor retains heavy, chamfered ceiling beams with scroll stops. A fireplace has been partly blocked with a later replacement. The right-hand range also features chamfered ceiling beams, but no stops are visible. A chamfered lintel is visible at a doorway on the rear, now partly blocked. The rear wing incorporates a chamfered granite segmental arch on the northwest, which was originally an exterior entrance and now forms a door arch from the kitchen extension to a rear sitting room. A fireplace with a chamfered granite lintel is located in the gable end on the southwest. Roof timbers include heavy, slightly curved principals with trenched purlins in the left-hand range on the southeast. An early 18th-century cellar rafter roof is found in the right-hand range on the north, and a light collar rafter roof is present in the rear wing on the southwest.
