20 Tamlaghduff Road, Bellaghy, Magherafelt, Co. Londonderry, BT45 8JQ

This single-storey house at 20 Tamlaghduff Road, built between 1820 and 1839, stands facing east approximately one and three-quarter miles north of Bellaghy village in County Londonderry. It is a four-bay, direct-entry dwelling of rendered and whitened roughcast with a black base of slight projection. The roof is thatched between parapet gables, with rendered and corbelled chimneystack serving the kitchen fireplace and the wall dividing the living room from the bedroom; each stack carries two plain pots.

The front elevation features a timber-framed and sheeted half-door with a six-pane glazed upper panel, flanked to the south by two and to the north by three pairs of vertically sliding sash windows with central mullions. The window frames are exposed, sash stops are moulded, and sills are set at traditional depths. The right-hand gable contains a similar sash window. The rear elevation shows a complex sequence of openings: from the north end, a vertically sliding window of increased width, a pair of vertically sliding windows, a timber-sheeted door with a six-pane glazed upper panel, two pairs of vertically sliding windows, a matching door, and a pair of vertically sliding windows. All windows share the same characteristics as those on the front.

The house and an adjacent roadside structure appear on the Ordnance Survey map of 1830, with further extensions to the south end and to the rear of the roadside block shown by 1856–57. The 1858 valuation records Patrick Scullion as the occupant, with Sir John Pares as immediate lessor and a rateable value of 15 shillings. Patrick Scullion was the father of James Henry Scullin, Prime Minister of Australia from 1929 to 1931. Scullion emigrated to Australia as a railway worker in 1848 at age twenty and his son was born on 18 September 1896 near Ballarat, Melbourne. The future Prime Minister visited his father's birthplace during a visit to Ireland in 1933.

Inappropriate replacement windows were installed with Northern Ireland Housing Executive grant assistance. A grant for re-thatching was paid in 1994, followed by a further grant in 1996 for replacement windows and doors. A thatched barn that stood in front of the house between it and Tamlaghduff Road was demolished in early 2006.
