46 Castle Street, Ballycastle, Co Antrim, BT54 6AR

This is an early 19th-century house, likely built between 1840 and 1859, situated within a terrace in Ballycastle. It is a three-bay, two-and-a-half-story building with an interesting roofline visible from the street. The building has undergone substantial renovation, resulting in the loss of much original historic material and the addition of a dominant shopfront, which diminishes its architectural interest.

The front elevation, facing Castle Street, has a ground floor with a doorway leading to the dwelling, topped with a fanlight. To either side of the shop door are two narrow display windows, set within a framed and glazed shopfront. The shopfront incorporates a decorative French-style awning and a projecting plastic sign with painted lettering. A segmental arched gateway is positioned to the left of the entrance. The first floor features three vertical windows, each with a small night vent. A lower window is situated above the gateway. The roof is in two sections, with the portion over the gateway having a lower ridge line and a different pitch. The walls are roughcast and finished with large coloured tiles beneath a name fascia. The roof is slated, with a small chimney stack at the ridge where the roof pitches change. A Velux-style window is visible on the main roof.

A two-bay long rear return is finished with a wet-dash render and painted. Single-story, flat-roofed extensions project from the eaves, extending further with a secondary flat roof. The building aligns with the established terrace building line, with a change in level between the gateway and the dwelling's entrance, where two steps are present. The building is currently used as a florist and plant business.

The 1832 Ordnance Survey map indicates its presence, and early surveys show Victorian details on the shopfront. It’s likely the building was renovated during the Victorian period, like many of its neighbors. A survey from October 1972 described the building as a two-bay rendered block with plain sash windows on the first floor, a vertical division between them, a pilastered entrance surround, triple windows, and a modern display window.
