Mostyn House

Mostyn House is a large, three-story town house built of brick with stuccoed and pebbledashed elevations, dating from the 18th century. It has a medium-pitched slate roof hidden behind a stuccoed brick parapet. The symmetrical facade has five bays, with stucco string courses, quoins (likely over an earlier stone base), and decorative architraves to the windows. The ground floor now features large modern double doors and shop windows. The first floor retains its original 12-pane sash windows to the four outer bays, while the upper floor has three, smaller 12-pane sashes. A rectangular, projecting oriel window with tripartite 20th-century glazing and a hipped slate roof is centrally positioned on the first floor; this has a heraldic plaster cartouche on the apron.

The original, fine oak staircase remains, consisting of a narrow “well” design. It features fluted and turned balusters, an exaggerated swept handrail, and fluted columnar newels. A large, fielded panel dado runs along the bottom flight, with fluted pilasters having rustic Ionic capitals. The first-floor landing has six-panel fielded doors and plain moulded architraves. One first-floor chamber retains large-field panelling to its road-facing wall, along with fielded panelled window reveals and seats. Decorative plasterwork including acanthus and palmette motifs on the ceiling and egg-and-dart to the cornice is contained within three compartmented bays, separated by lateral beams.

The front right-hand chamber retains its full raised and fielded large-field panelling, window seats, reveals, and a deep moulded cornice. A contemporary stone fireplace with fielded sides, a frieze, and a basket arch with simple panelled pilasters is also present. Bolection-moulded architraves frame two-panel doors with fielded reveals. Pegged doorcases and the original two-panel door to the second floor remain, along with a simple stone fireplace matching the style of the other. The brick barrel-vaulted cellar is accessed by stone steps. Ground-floor panelling was reportedly removed in 1981, although some moulded cornicing survives.
