Boskennal Farmhouse, Including Adjoining Outbuildings and Rear Garden Walls

Boskennal Farmhouse, together with adjoining outbuildings and rear garden walls, is a building that dates primarily to the 18th century, with alterations and extensions made around the late 18th or early 19th century, and again in the mid-19th century. It is constructed mainly of granite rubble with granite dressings, with a dressed granite front. The roofs are covered in both Dry Delabole slate and scantle slate, and brick chimneys are located on the gable ends. The house has an overall U-shaped plan with an additional service wing to the front of the left-hand side. The main house contains two front parlours flanking a wide entrance hall, which leads to a large stair hall. This stair hall features an 18th-century staircase with a moulded closed string and column-turned balusters. To the right of the stair hall is a dairy projecting to the rear, which adjoins a granary running parallel with the rear of the house. To the left of the stair hall is a back kitchen, and then a mid-19th century servants’ hall or kitchen with servants' chambers above. A large, single-storey service wing, likely a former dairy, sits in front of the kitchen wing, and the granary has granite steps leading to a doorway in its northeast end. The rear dairy has particularly thick walls, likely dating to the 17th century. The front of the farmhouse is symmetrical, with three windows and a central doorway with a narrow window above. A plinth and flat arches with projecting keystones are visible. The front features a circa late 18th or early 19th century four-panel door and hornless sash windows of the same date with glazing bars. The rear of the kitchen wing has a three-window front. The stair hall contains a brick wall between two stone walls, with granite quoins. The interior is largely unchanged since the 19th century and retains many original features, including the 18th-century open-well staircase, 18th-century two-panel doors to first-floor rooms, mid-19th century panelled doors to ground-floor rooms, mid-19th century plaster ceiling cornices in the parlours, and a mid-19th century cast-iron horseshoe grate in the left-hand front chamber.
