Trewollack House

Trewollack House is a house dating from approximately 1830 to 1840, with alterations from the later 19th century and subsequent changes. The front facade is granite ashlar with granite dressings; the right side is granite ashlar, while the remainder is stone rubble. It has a hipped slate roof with stacks at the left side and to the rear right, featuring stone and rendered shafts.

The house follows a double-depth plan, with a central entrance leading to an entrance hall and a stair hall situated to the rear centre. Principal rooms are located to the front right and left, and another is found to the rear right on the garden front. Service rooms are positioned to the rear left.

The exterior presents a symmetrical three-window front on a plinth, incorporating pilasters and deep eaves. A central granite Tuscan portico, with a flight of three granite steps, a cornice, and a blocking course, provides access. Within the portico are half-glazed double doors with margin glazing typical of the 19th century. Tall 30-pane sashes are on the ground floor, flanked by windows with cambered arches and voussoirs. The first floor has a cill band course and three 20-pane sashes, also with cambered arches and voussoirs. All windows visible externally date to the 19th century.

The right side features a symmetrical three-window front consistent with the main facade, containing 19th-century windows, a plinth, and a band course with pilasters. It includes three tall 30-pane sashes on the ground floor and three 20-pane sashes on the first floor. The left side has an external stack to the right, a 20th-century door, and a 20th-century greenhouse attached. The first floor features a 19th-century round-arched 12-pane sash with radial glazing bars (formerly a taller window) and a 12-pane sash with a brick cambered arch.

At the rear, two 20th-century 12-pane windows are visible on the ground floor, with brick cambered arches, accompanied by two similar windows on the first floor, and a central 12-pane sash.

The interior, which was not fully inspected, includes a stair hall with a moulded cornice. Six-panelled doors, set within moulded architraves, lead to the principal rooms. An open-well staircase is present, with stick balusters and a moulded wreathed handrail.
