54 Main Street, Moira, Craigavon, Co. Armagh, BT67 0LQ

A two-storey, three-bay mid-terrace Georgian townhouse built around 1735 as part of the early development of Moira, centrally located on the north side of Main Street. The building is constructed of natural finished coursed rubble basalt with brick surrounds to windows and doors, though the brick around the windows and doors is distinctly newer Victorian brick rather than Georgian, dating from around 1915 when the building underwent modernisation.

The pitched roof is covered in natural slate with clay ridge tiles and a clipped verge to the right-hand gable end. Galvanized ogee rainwater goods with uPVC downpipes serve the main elevation, while a cast iron soil and vent pipe, painted green, is located at the rear. A brick chimney with a single clay pot sits to the right side of the coach entrance.

The principal south-facing elevation is symmetrically arranged across three bays. Windows are generally early 20th century single-glazed 1/1 timber sliding sash with smaller top sash, horns, and painted white finish, set beneath rectangular stone cills with 1½ red brick flat arches. The principal entrance is a six-panelled timber door with a fixed light over. To the right of the front entrance is a double-width opening with a single-glazed timber casement window. The left gable forms a sidewall of the adjacent carriageway at street level and abuts number 52 Main Street at first floor level.

The rear elevation is symmetrically arranged, with a new door formed in an original window opening to the left. The central first floor window is a single-glazed opaque sliding sash with blue-coloured marginal panes. A masonry constructed shed with pebbledash finish and tile roof encloses the rear garden on either side.

The building was originally residential, appearing on the 1833 Ordnance Survey map as part of two long rows of terraced houses. By the 1858 edition, it is shown with a small return and extensive formal gardens to the rear, though later maps suggest these gardens were lost by the early 20th century. Throughout the 19th century it functioned as a townhouse with multiple tenants, with Reverend Sam Graham serving as landlord from 1866 until 1908, when Reverend Robert McFarland took over.

A significant change occurred around 1915 when the building converted to a post office, an alteration reflected in the replacement of its original Georgian windows and door surrounds with newer early 20th century designs. The 1916 Ordnance Survey map identifies the building as a post office, though formal records do not refer to it as such until the 1935 Rateable Valuation Binders valuations, which note the property comprised a kitchen, scullery, and post office on the ground floor with three bedrooms on the first floor. The post office remained in operation until around 1976, when the 3rd General Revaluation Lists indicate it functioned only as a shop. It is currently in use primarily as two shops.

The building retains urban vernacular proportions and possesses group value with other listed townhouses on Main Street, including numbers 76-80. Despite loss of interior fabric due to modernisation, the plan form and internal character illustrate the historical transition from residential to commercial use. The building is street-fronted, with access through the adjoining carriageway leading to the rear of number 52 Main Street only. It is located within a conservation area.
