Trevan House

Trevan House is a house dating from the early 18th century, located on Dolphin Street in Port Isaac. The exterior is rendered stone rubble with a slate roof, featuring gable ends and asbestos slate on the rear. A 20th-century brick chimney stack is situated on the right-hand gable end.

The house likely has a double-depth plan, with two reception rooms on the front and two smaller service rooms towards the rear. The front facade is a regular two-window design, although the left side is partially hidden by a later adjoining building. The ground floor features a tall, narrow 12-pane sash window on the left, positioned next to the adjacent property; a 20th-century four-panel door with a moulded cornice and slate hood; and a 19th-century 20-pane hornless sash window with crown glass and an exposed moulded sash box to the right. The first floor has two sashes similar to those on the ground floor. The timber eaves cornice is elaborately carved with a high-quality Doric frieze.

The rear elevation is rendered and has 20th-century windows and dormers. The interior is not accessible, but the quality of the eaves cornice carving suggests the possibility of other interesting features within. The house was the home of Frederick Trevan, a local doctor and author of The History of Port Isaac and Port Quin (1833-1834).
