19 Ranaghan Road, Maghera, Co. Londonderry, BT46 5ND

19 Ranaghan Road is an early 19th-century, single-storey, four-bay direct entry house situated approximately one mile west of Maghera in County Londonderry. Built between 1820 and 1839, it appears on Ordnance Survey maps from 1832 and 1854.

The house faces east and is constructed of limestone chips above a recessed, blackened base. The original thatch roof is now covered with corrugated iron. Two plain chimneys serve the kitchen and parlour fireplaces respectively. A projecting porch with shallow pitched corrugated iron roof provides entry through a two-panel timber door; a top-hung window to the left of the porch is now partially glassless. The main elevation has four windows with top-hung timber frames of traditional sill depths, all currently without glazing.

The primary architectural interest lies in the retention of the original roof construction, including scarfed crucks, which remain clearly visible despite the external alterations. Although the layout has been altered, the original form and internal arrangement are readily discerned.

Adjoining the house to the north are a corrugated iron-roofed store and shed. A connecting section with vestiges of natural slate roofing links the dwelling to a two-storey barn with natural slate roof and random rubble stone walls, roughly plastered. The barn is divided into two sections. The front has two entrances, with a timber ledged and sheeted door on the right and an open entrance on the left. The upper floor features a large loading bay-type opening flanked by smaller openings with brick sills, with a further two small openings at intermediate level. The end gable displays alternating brick quoins at its corners and a plain timber bargeboard. The rear elevation of the barn has a window and door opening on the ground floor and two openings on the upper floor.

The building represents a rare survival of vernacular construction with structural evidence of traditional cruk roof framing, though later alterations have impacted its historic character.
