Description

Calthorpe House is a detached house dating from the early 19th century, with a later 19th-century addition at the rear. It is constructed of stone rubble, rendered at the front and roughcast on the left side; remnants of slate hanging were visible on the right side wall in 1987. The roof is covered in asbestos slates. The property has a double-depth plan with an added closet wing.

The two-storey house, with a semi-basement and garret, sits side-on to Belmont Road, with a gabled two-window north-facing front. The ground floor features a rusticated facade with fluted Ionic pilasters and three round-arched openings. The right-hand opening contains a doorway, the middle an 6-paned sash window, and the left-hand opening a pair of French windows, both also with 6-paned glazing bars. A glazed verandah with twisted cast-iron columns stands in front of the ground floor; a solid wall is located on the left, with late 19th-century glazing infilling on the right. The upper floor is flanked by panelled pilasters supporting a triangular pediment. Windows have moulded architraves and 6-paned sashes. A pair of plain sash windows are set into an elliptical-headed recess in the pediment's centre. A barred sash window is visible on the upper storey of the left side wall. The closet wing has two windows with coloured glass.

The interior was not inspected. The house appears on the 1840 tithe map of Ilfracombe situated in an isolated position surrounded by fields.
