Attached Outbuilding at Holy Hill House, 78 Ballee Road, Artigarvan, Strabane, Co Tyrone, BT82 0AA

Attached Outbuilding Range at Holy Hill House, Artigarvan, County Tyrone Grade B1 — Dating from approximately 1810

This is a single-storey range of vernacular outbuildings forming part of an extensive farm complex within the demesne of Holy Hill House, and dating from around 1810. The complex as a whole has Plantation-era origins. The listed extent includes the outbuilding range itself, a former dog house, an ash pit, the farmyard walling, and the entrance gates.

The building is rectangular on plan and aligned east–west, positioned to the north-east of the farmyard and immediately west of Holy Hill House. All roofs are pitched natural slate. There are no rainwater goods. Walls are of thick rubble stone, limewashed, with a painted base course. Window openings are multi-pane timber with contrasting frames and no cills.

The main range faces south and originally comprised a slaughterhouse and an apple house, with a stick house at the left (western) end. The west elevation is blank and is abutted by a low whitewashed rubble-walled enclosure that formerly served as an ash pit — used to collect offal from the slaughterhouse for use as fertiliser. The north elevation is abutted by a lean-to structure set against the farmyard wall, containing an entrance door only, which formerly served as a dog house. The east elevation abuts the rear extension of the main house.

The farmyard setting to the west of the main house is of rubble stone construction throughout. The farmyard wall on this side terminates at the byres building at a gated access, with painted cast metal gates hung on rubble stone piers. The piers are topped with painted cast metal cockerel finials, installed by the current owner. The wider setting consists of a concrete farmyard with associated outbuildings, all set within a demesne of parkland, pasture, and gardens.

The outbuildings appear on all three editions of the Ordnance Survey map (1833, 1854, and 1905). Griffith's Valuation of 1856–64 records the following outbuildings with measurements across the wider complex: two dairies, a granary house, a coach house, a fowl house, a boiler shed, two stables, a shed, a cow house, and two offices. From physical inspection it appears that the farmyard was largely constructed in a single phase of improvement, with some later additions. Although the vernacular character of the buildings makes precise dating difficult, their appearance is consistent with an early 19th-century date.

The history of the estate supports this dating. In 1736 John Sinclair commissioned William Starrat to draw up a map of the estate, which unfortunately omitted all buildings. An estate map in the Abercorn papers, dated 1804, identifies the property as belonging to George Sinclair but again shows no buildings. The estate is understood to have been cultivated and improved, and the house enlarged, during the 1730s and 1760s under John Sinclair, who owned it from 1718 to 1770. His son George, who had trained as a linen merchant and owned the estate from 1770 to 1804, continued cultivation and established a mill after 1779. Under James Sinclair, justice of the peace, who owned the estate from 1804 to 1865, the estate was greatly developed and many estate buildings were erected. It is the construction activity under James Sinclair that most plausibly accounts for the present farm range.

The Ordnance Survey Memoirs give an unusually detailed account of James Sinclair's agricultural achievements and his influence on the surrounding parish of Leckpatrick. The Memoirs describe him as "the only resident proprietor" in the parish and praise his "skill in every department of agriculture," noting that the woods of Holy Hill yielded timber for his tenants' houses and farming implements, and that its nurseries supplied plants and trees for their gardens and fences. The Memoirs comment that "it would afford a good practical lesson to many of our proprietors to visit these newly formed farms," and record in detail his use of turnip cultivation, irrigation of meadows, burning of clay for manure, and employment of oxen in husbandry — practices noted as exceptional in the district at the time. James Sinclair and a neighbouring resident incumbent, Mr Brownlow, are credited with setting a standard of agricultural improvement that their neighbours progressively adopted.

The building is a relatively rare surviving example of a complete farmyard group associated with a large landed estate of this period. It retains its early proportions and style and has been well maintained, with only isolated sympathetic replacements. It makes a positive contribution to the demesne and carries group value in association with the other listed structures at Holy Hill.
