Trevacoon

Trevacoon is a two-story house, likely dating from the late 17th to early 18th century, with later alterations. The front facade is painted roughcast with a painted ashlar plinth and features a three-window arrangement. It has 12-pane sash windows set in plain reveals with slate sills. The roof is a broad, grouted slate hip with a pair of ridge stacks, capped by an eaves cornice with mutules. A long, pointed stair light with intersecting tracery is located on the west side. The east side has a two-window range with a window to the right and a six-panel door with a beaded frame and a fanlight, set within a large stone Greek Doric flat porch featuring two baseless columns with fluted necks and pilaster responds.

Attached rear buildings form a three-sided narrow court, and behind the main house is a steep-roofed range with end stacks and a two-story front to the court. This section appears to originate from the late 17th to early 18th century, despite having 20th-century windows. A painted rubble stone range, built in two stages, runs westwards, with ridge and west stacks, and is two stories high with irregular fenestration to the north and rear. To the rear southeast of the main house is a truncated block with a corrugated asbestos roof, followed by a low, two-story, L-shaped range of outbuildings, some of which were derelict in 1989, all with grouted slate roofs. A west-facing range includes a lean-to with a 9-pane window, a metal-clad door, and a blocked arch-headed doorway.

The internal layout includes a dog-leg closed-string stair at the north end, featuring turned balusters. Various small rooms are present, along with large meat-hooks in the joists of a southeast room, alongside a domestic fireplace. A north-facing range has three arched entries with keystones; two provide access to a tunnel-vaulted space partially divided by inserted lateral walls, while a third gives access to a largely collapsed conventional two-story range. A sash window and two small loft windows are also present. A massive ivy-clad chimney at the west end contains a correspondingly large fireplace. A straight joint in the ground floor aligns with the stack, leading to an end section with a door, window, and a boarded loft opening. An external west-end stair leads to a loft door. The condition of the outbuildings is poor.

Inside the main house, a spine passage extends from the east door to the west stair hall. This passage features two bays of plaster quadripartite vaulting on molded brackets; the first bay opens to the south onto a shallow, half-elliptical recess with an arched head. The stair hall has a large dog-leg stair with plain stick balusters, fan molding in the spandrels of the stair light, and a coved plaster ceiling. Two principal ground floor rooms have six-panel doors, although their surrounds have been removed. The northwest room has a vine cornice and a segmental arched recess on the east wall; the northeast room has a plaster-molded cornice. Fireplaces have been removed from both rooms. Broad, collarless roof trusses are also present. An older range behind the main house, accessible via a servants’ stair with reused turned balusters, has a six-bay hewn timber collar-truss roof.
