Comprigney

This is a country house dating from the 18th century, with a possible core from the 16th century, and extended in the early 20th century for George Coulter Hancock. It is constructed of stucco or render on masonry, with hipped roofs covered in Delabole slate and rendered axial stacks. The house has a fairly large, rectangular double-depth plan and incorporates classical-style features.

The southeast front is nine bays wide. The right-hand side represents the original 18th-century house, symmetrical with seven windows, and the left-hand side is a two-bay return of the early 20th-century projecting wing. A plinth is visible, along with moulded architraves with pediments to the ground floor windows, a moulded string, and an eaves cornice. The windows are early 19th and early 20th century sashes with glazing bars. A central, round-headed doorway is recessed, with panelled reveals and a spoked fanlight above a six-panel door. The left-hand return shows an early 20th-century three-bay garden front, with the central bay broken forward and topped by a triangular pediment with modillioned cornices and an oculus above a small nine-pane sash window on the first floor and a Venetian window on the ground floor. Other elevations remain largely unaltered since the early 20th century.

The interior retains many high-quality features, likely from the mid-18th and early 20th centuries, including a dogleg staircase with a closed string, column-turned balusters, and a moulded mahogany handrail. Round-headed doorcases with panelled reveals, panelled doors and shutters, moulded architraves, moulded plaster ceiling cornices (some carved), and numerous chimney-pieces are also present.

Historically, Comprigney was a 24-acre manor in the 16th century, part of the Duke of Arundell's estate. In 1718, it was the birthplace of the Reverend Thomas Vivian; his son, John Vivian, is believed to have established the Cornish copper trade, and his son, Sir Richard Hussey Vivian, distinguished himself at Waterloo and became Baron Vivian of Glynn and Truro, and served as MP for Truro. The house remained in the Vivian family's possession until it passed to William Mitchell, who died there in 1845. During World War II, the house was used by the American Forces.
