Trevissome House

Trevissome House is a country house dating from the early 19th century, with substantial extensions added in at least two phases during the later 19th century and into the 20th century. The building has stuccoed walls and flipped scantle slate roofs with moulded plasterwork beneath wide eaves soffits. Brick chimneys sit over cross walls.

The original plan comprised three reception rooms arranged in line facing the garden, with a passage behind leading from a side entrance on the right (east) to a stair hall, with a service room beyond at the rear of the left-hand room. A further reception room at the front left (west) is probably a later addition made in the same style, accompanied by a service room behind and an adjoining late 19th-century kitchen with a pyramidal roof. In the late 19th or early 20th century, a U-shaped service range was added to the rear of the original house, enclosing a small courtyard. Parts of an earlier house may be incorporated into the west side. A large 20th-century extension adjoins to the west.

The building is two storeys. The south garden front displays a 2:1:1:1 bay arrangement, originally probably symmetrical, with two window bays on the left added later in the same style. The south front features a stucco plinth, rusticated quoin strips, a hood string, and moulded aprons beneath most first-floor windows, with a first-floor sill string. Bays 1, 2 and 4 have recessed window surrounds. Bays 3 and 5 are broken forward and contain 3-light canted bay windows. The fourth bay, originally central, has a round-arched window surround to the ground floor. All windows are circa late 19th or early 20th-century horned sashes with plate glass. The 20th-century extension on the extreme left is set back slightly.

The east entrance front comprises an original 3-window section on the left and a circa late 19th or early 20th-century 4-window service wing on the right. The original part features similar stucco detailing to the main front. The entrance on the right has a round-arched doorway with an original 6-panel door, fanlight and panelled reveals, flanked by rusticated pilasters with a Doric distyle wooden portico in front. The original hornless sashes of the main section have had their glazing bars removed and plate glass inserted circa late 19th or early 20th century. The original horned sashes of the service wing to the right also now have plate glass.

The interior is little altered and retains most of the original carpentry, joinery and plasterwork. Mahogany 6-panel doors with original architraves give access to the reception areas. The entrance passage and first-floor area adjoining the stair hall have ceiling bands with trailing roses. The stair hall contains a geometric open-well open-string stick baluster stair with a mahogany handrail wreathed over the newel, and a moulded ceiling band with rosettes. The left-hand reception rooms were not inspected. The original middle room has an egg and dart cornice and a moulded and carved band. The right-hand room contains a fine marble chimney piece with engaged fluted columns and a festooned frieze, dentilled cornice and ceiling cornice featuring egg and dart, harvest band, and a central rose with concentric rings of carved acanthus. A doorway between the first-floor passage and the room over the entrance has pilaster jambs and a fanlight.

Despite the removal of some glazing bars and replacement of sashes, Trevissome House remains a fairly complete example of its period with some good original detail. While substantially extended, it retains strong architectural qualities to its east and south fronts.
