No. 17 with Walls and Gatepiers

No. 17 is a coach house and garden building constructed in 1843, with 20th-century alterations, designed by James Wilson. The building is made of limestone ashlar and features a slate roof with two moulded ridge stacks. It has a U-shaped plan with two forward wings.

The exterior is two storeys high. Each wing has an open pediment at the gable end supported by paired brackets at the corners. The wings project slightly, with smaller pediments above first-floor six-over-six pane sash windows that have segmental arches and large keystones. The central, set-back range contains two six-over-six pane sash windows with hoods on brackets at eaves level. There is a 20th-century slate-roofed lean-to on the ground floor with 20th-century doors.

The gatepiers at the front of the courtyard feature cornices on paired brackets and pyramidal caps, flanked by walls that enclose the courtyard. The three-bay garden front has dentil cornices on the stacks flanking the central bay. The parapet has moulded coping and vertically pierced panels over each bay. The returned cornice has paired shaped brackets at the corners and similar brackets above raised surrounds and to the sills of the six-over-six pane first-floor windows in the outer bays, with moulded archivolts, impost string courses, and large radial fanlights above 20th-century half-glazed doors on the ground floor. The central bay is slightly recessed and features moulded archivolts and imposts above three full-height semicircular arches, with the impost cornice continuing under pierced stone radial fanlights and over tall small-paned 20th-century glazing. The interior has not been inspected.
