Trevenson House

Trevenson House is a house, built in 1797 and remodelled around the early 19th century. It is constructed of pink Tolgarrack stone, with an ashlar front and granite dressings. The roof is slate, with a granite parapet to the front and granite eaves cornices to the sides and rear. The stacks have been truncated below the roofline.

The house has an L-shaped layout, with the main rooms and staircase in the front range and a service wing at the rear. It exemplifies a Neo-Classical style.

The south-east front has two bays to the left, one bay in the centre, and two bays to the right. It features a granite parapet, cornice, stringcourses, and rusticated quoins. The central bay projects forward and contains a Neo-Classical Venetian window. The windows are four-pane sashes. The ground floor has early 19th century granite bay windows with tripartite sashes and glazing bars. A large granite porch has pilasters, a cornice, a semi-circular fanlight, and tall sashes with glazing bars on splayed sides. The north-east return front has three bays to the left and two bays to the right; the left bay is blind. A single-storey stone canted bay window is located to the left of centre.

The interior, only partly inspected, includes an Edwardian staircase with a timber balustrade. The handrail is heavily moulded and ramped up to the newels, with an arcaded screen on the landing.

Trevenson House was built in 1797 for Thomas Kevill, the steward of the Tehidy estate, and it replaced an earlier house on the site.
