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

Holy Hill House is a detached, symmetrical five-bay, three-storey house built around 1670, set over a concealed basement. The house is square in plan and faces east, with a full-height canted bay projecting from the north elevation. Several extensions project from the rear, creating an irregular plan at the back. The roof is pitched with natural slate in M-profile, slightly sprocketed, with angled clay ridge tiles and roughcast chimneystacks topped by polygonal terracotta pots. Cast iron gutters run along the eaves, with internal downpipes not visible on the front elevation.

The walls are painted roughcast, with a smooth rendered plinth visible at basement level on part of the south elevation. Windows are generally timber sliding sash of varying configurations, diminishing in size towards the upper floors on the front elevation. The principal east elevation is symmetrically arranged about a central entrance door, which has a lugged sandstone surround and threshold. The entrance comprises double-leaf timber glazed doors in Dutch style with a timber shutter behind, divided horizontally into three sections. The ground floor has 9/6 sash windows (replacements), the first floor has 6/6, and the second floor has 3/3.

Lean-to additions flank either side of the main block, screened by painted roughcast flanking wing walls surmounted by a masonry cap with decorative scroll detailing and a ball finial at the outer edge. The south wing features a timber and stud double door with concrete threshold. The north wing door is currently boarded up.

The south elevation is asymmetrical, with painted weather slating to the first and second floors on the right side. There is an 8/8 window on the left and two 6/6 windows on the ground floor. A modern metal bridge with concrete steps projects from what was formerly a door at second floor level and bridges over the coal cellar. A single-storey lean-to extension with natural slate roof (replacing an earlier glazed roof) projects from the right, while a dipartite side-hung 12-light window sits to the left with a 3/3 sash to the right.

The north elevation features a full-height canted bay to the right, with 3/3 windows on the second floor, 6/3 on the first floor, and 9/6 on the ground floor either side of a 9/9 window extending to ground level with a stone slab threshold. To the left is a 6/3 window on the second floor and a single-storey lean-to extension with UPVC gutters.

The rear elevation is abutted by several extensions. At the left is a double-height gabled extension dating from around 1850. The centre has a one-and-a-half storey gabled extension linking to an attached outbuilding at the rear and accessed from the main block by a short skewed link. A twentieth-century lean-to sanitary extension rises from the scullery, supported on the right by a straight pier. The exposed section has single windows at first and second floor levels to the left of the sanitary extension. The double-height extension features double-glazed French doors with a large toplight, accessed by four stone steps bridging a ditch, and three 1/1 windows with horns. The central extension has an original four-pane window to the attic storey and a replacement 3/6 window, accessed by a timber-sheeted door with brass furniture at the south side, with a further gabled addition to the south. The skewed link has a single 3/6 window. The sanitary extension has 3/6 windows. The scullery features a timber-sheeted door at the right cheek and two six-light windows.

Holy Hill House occupies an extensive demesne consisting of lawns, mature parkland, and pasture on undulating land to the north-east of Strabane town. An extensive farm complex with rubble walling stands to the rear. The house is accessed from the road via wrought and cast iron gates set between square stone rubble gate piers to the west, which would formerly have been the back avenue.
