Stable Block, Carnell House

The Stable Block at Carnell House is a mid-19th century, two-storey, U-plan neoclassical building that was originally a stable and coach house but has since been converted into flats. It features a central high segmental-arched entrance with a pediment, and a single-storey gabled block that once served as a loose box, cheese house, and scullery, attached to the fourth side of the courtyard by coped screen walls. The building is constructed of sandstone ashlar, with red sandstone ashlar pilasters and a pediment on the principal northern elevation, and roughly coursed sandstone with raised polished ashlar dressings on the side and courtyard elevations. It has a base course and an eaves course, with regular fenestration featuring raised ashlar margins.

The entrance has a recessed arch with half-columns that extend to the soffit roll and a low pediment above. The main elevation has three bays on either side of the entrance, arranged in a 1-2-2-1 grouping, with wide plain pilasters. The eastern elevation has three bays, including a central doorway and a bipartite stone-mullioned window on the ground floor to the left. The western elevation is roughly four bays wide. The courtyard elevations display irregular fenestration, including two segmental-arched former coach house openings to the right of the entrance, which are now glazed, and a 20th-century timber porch supported by timber columns in the northwest corner. The single-storey southern block features timber-boarded sliding doors.

The windows are predominantly timber sash and case, with eight-pane glazing on the ground floor and four-pane glazing on the first floor. The building has ashlar-coped skews and predominantly coped sandstone ashlar stacks with a string course and buff clay cans. The roof is covered with grey slate.
