Trevales House

Trevales House is a small country house dating from around the middle of the 18th century, with a substantial extension added in the late 19th century. The front of the house is built with granite ashlar, while the extensions are of dressed granite and painted rubble. The roof is covered in Delabole slate, with a half-hipped section over the original part of the house and hipped or pedimented gables elsewhere. Rendered brick stacks are visible above the original main section, at the rear of the extension, and over a window bay at the right-hand end.

The house was originally laid out as a double-depth plan. The original part comprises two reception rooms at the front—a parlour on the left and a former parlour on the right that was remodelled in the 19th century to create a two-storey galleried hall, incorporating a former central entrance hall. The original stair hall sits between the rear rooms, which include a stone-flagged kitchen to the left. An integral service wing runs along the left side, and there are two cellars: a large vaulted cellar beneath the left side of the house and a smaller cellar under the staircase. A large cross wing was added to the right side of the original house in the late 19th century, set two rooms deep and featuring projecting two-storey bay windows.

The south-west front has two storeys and a 1:3:1 bay arrangement. The left bay is lower and forms a coped gable end of the service wing. The central three bays are symmetrical with three windows, including a central doorway. The front has a plinth and a parapet string, with an ashlar parapet (extended in the 19th century over the extension) that now forms the eaves of the roof. The windows are shallow-keyed arches. An original panelled door is set within a circa early 20th-century glazed porch with a low-pitched gable and shaped bargeboard. The windows are late 18th-century paired 12-pane sashes, with some original glass, except for a horned copy at ground floor level on the left. The 19th-century wing projects forward on the right and has a central four-light mullioned window with side lights within a two-storey projecting bay, topped with a triangular pediment and moulded cornice. A similar bay window is on the return wall, lighting a rear room. The rear elevation has three 18th-century paired sashes and one replacement. A large four-light transommed window with round-arch-headed lights and coloured glass has been built out in front of the former stair window.

The interior was largely remodelled during the 19th-century extension, featuring plaster ceiling cornices, chimney pieces, and a cantilevered gallery over the hall. However, some original 18th-century features remain, including a dog-leg staircase with a closed string and column-turned balusters, a stone-flagged kitchen floor, and brick vaulted cellars with original storage compartments.
