20 Ballygillen Road, Cookstown, Co Londonderry, BT80 0AJ

20 Ballygillen Road, Cookstown is a detached two-storey farmhouse built around 1858 by Robert Browne, constructed of snecked and rubble stone. It is well preserved and picturesquely sited within a rural cluster of stone outbuildings and modern sheds accessed via a long private lane off Ballygillen Road, northeast of Cookstown.

The house is long and rectangular in plan with a single-storey pitched return to the rear northwest. The front southeast elevation is four bays wide. Windows on both floors are square-headed with painted cut-stone sills and red brick voussoirs over. The ground floor contains 6/6 timber sliding sash frames, while the first floor has 3/6 timber sash frames. A replacement timber door sits in the third bay to the right, with an original rectangular overlight above, set upon a concrete step. A cut-stone datestone set at the top left of the door is inscribed "R. BROWNE A.D. 1858".

The side southwest elevation is gable-ended with roughcast render finish and no openings, with a chimney at the apex. The rear northwest elevation features square-headed windows on plain cut-stone sills: 18-light timber casement windows to the ground floor and 9-light timber casement windows to the first floor. External walls are snecked and rubble stone to the front elevation and roughcast render to the sides and rear. A continuous projecting red brick eaves course runs around the building. The pitched roof is covered in natural slate with four simple brick chimneys with profiled stepped capping. Cast-iron rainwater goods are fitted throughout.

A single-storey outbuilding is attached to the northeast along the same building line. The single-storey return to the rear has an 18-light timber casement window to the rear gable and an external timber door to the northeast elevation, with roughcast render walls and a pitched natural slate roof. The attached northeast outbuilding is whitewashed stone and render with two square-headed openings to the rear fitted with timber sheeted doors, pitched natural slate roof, and replacement uPVC rainwater goods. A further single-storey pitched outbuilding to the northeast and another to the west feature metal sheeted roofs; the western outbuilding has an elliptical headed opening with timber-sheeted door to the south gable and a small round-headed opening to the gable above. Remaining outbuildings are pitched with metal roofs and whitewashed stone and render.

A cast-iron water pump, installed around 1858, stands in the rear north yard. It features a slender round fluted pedestal with an elongated rounded cap and a downturned spout to the northwestern side with a downward-projecting handle. The pedestal is fluted to top and bottom, with a square cast-iron base plate bolted to a stone base. The manufacturer's stamp embossed to the cap reads "W J SCOTT COOKSTOWN". The cap is fluted with an oval-shaped finial on top.

A building was shown on this site on the Ordnance Survey map of 1832 but was not recorded in the contemporary valuation, suggesting a modest single-storey structure below rateable value. The present dwelling was constructed in 1858 by Robert Browne, who remained in residence until 1893. He was succeeded by John Browne, who acquired the freehold in the same year. The property remained with the Browne or Brown family until at least 1957. The rural setting and cluster of outbuildings are well preserved and add significantly to the heritage value of this vernacular farm complex.
