Alphonsus House

Alphonsus House is a large house, originally the Dower House, dating to the late 18th century with additions in the late 19th century. The main structure is built of Malmstone ashlar walls with Bath stone dressings, featuring quoins, bands marking the first and second floors, a plinth, and window openings set within oval arched recesses. It has a low-pitched slate roof with wide eaves supported by carved brackets. The building is of symmetrical classical design, with extensions on three sides in an Arts and Crafts style.

The west front is three stories high and symmetrical, featuring three windows. It has sash windows in reveals; two windows now occupy the space previously held by a central porch. The north elevation displays the end of the main block with similar detailing and a two-story wing projecting from its east side. This wing has a steep tiled roof, tile-hung upper walls with scalloped bands, a lower brick wall, and a two-story gabled porch at the junction. The south elevation shows brick and tile service wings attached, of a lower height and complex form.

The rear (east) elevation presents a section of the main block built of brick in English bond, with blue headers. Two late 19th-century extensions are separated by a yard; the northern extension is larger and features a prominent gable above a two-story, splayed bay with mullion and transom windows.
