Description
St John's Mount and Mews Cottage is a two-storey villa with Gothic features, built in the 19th century. The exterior is finished in pebbledash with a slate hipped roof, featuring a band at the first-floor sill level and a plinth. The northeast entrance elevation consists of three bays, with the centre bay projecting over an open porch. This bay includes a cantilevered four-light bay window supported by corbelling, with buttresses extending to the ground. Beneath the porch is a doorway with a four-centred head leading to the rear, featuring a shallow Gothic fanlight with tracery and a door with Gothic panelling. The centre bay is flanked on the left by a two-light casement window above and a three-light casement below, and on the right by a two-light casement above and a three-light casement below. The southeast elevation has three widely spaced window bays, each projecting forward, with first-floor windows of two lights topped by gables and transomed two-light French casements on the ground floor.
Adjoining the house at its northern end is Mews Cottage, which is of similar date. The forecourts of the house and cottage are separated by a stone stub wall. Mews Cottage is also two storeys, rendered with a slate roof. The first floor features two two-light casement windows set across the eaves with gables, while the ground floor has a two-light and a three-light casement window. The entrance is located in a single-storey, two-window exposed stone wing that is at right angles to the main structure.
Inside, the villa boasts fine interiors in the Gothic style, including Gothic cornices, doors, shutters, arches, and chimney pieces.
