Causilgey

Causilgey is a country house built in the late 19th century, likely around 1870, and designed by G Devey. It is constructed primarily of killas rubble with granite quoins, sills, jambstones, mullions, lintels, and arch stones, potentially incorporating reused dressed stone from Tregavethan Manor. The roofs are of scantle slate, with gables except for a canted bay and a hip roof to the rear. The irregularly positioned rubble stacks sit over cross walls and gable ends, some featuring moulded strings or cornices.

The house has a very irregular plan, forming a shallow 'H' shape with further projections towards the north east and a lean-to to the rear, mostly one room deep. It is built in a Tudor vernacular style, with two storeys plus an attic. The south east front is irregularly arranged, consisting of a 1:2:1 bay arrangement, with a roughly central two-window main range flanked by projecting one-window gable ends. The main range has a roughly central entrance within an open, gable-ended porch with side walls of rubble. All windows feature granite mullions, with 20th-century glazing; ground floor windows incorporate transoms. A three-light bay window is located to the left of the doorway, above which is a two-light window. A large quadrant projection, likely an original bread oven, is situated at the left-hand angle. To the right of the doorway is a three-light window and a six-light window above, continuing to the left over the entrance; the middle two lights of the six-light window are 20th-century insertions. The projecting taller gable end to the left has a canted bay window to both the ground and first floors, featuring three lights in the middle and one light to each side, with a hipped roof and a two-light window to the gable. The projecting gable end to the right has three-light windows with transoms to both the ground and first floors. The rear elevation is also very irregular, with a canted bay towards the left, featuring a three-light transom window to the first floor, and a projecting entrance porch with a parapet and a basket-arched doorway, along with two small, single-light windows above. A gable roof dormer with a two-light window over the porch is linked to the rear gable of the taller front wing.

The interior was not inspected at the time of listing. Causilgey is described as a deliberately irregular and romantic composition, with the roof materials and their juxtaposition significantly enhancing the overall effect.
