59a Old Mountfield Road, Omagh, Co Tyrone, BT79 7ET

Detached multi-bay one-and-a-half-storey house, formerly a stable block, built circa 1875. Located on the north side of Old Mountfield Road, Omagh, the building is rectangular on plan and comprises a three-bay house to the south, with a coach house and store to the north.

The roof is half-hipped natural slate with crenellated terracotta ridge tiles over a brick cogged eaves course. Three red brick corbelled chimneystacks are positioned across the roof. The walls are constructed of squared-and-snecked rubble stone with stepped tooled sandstone quoins. Windows are replacement uPVC casements set within stepped tooled sandstone surrounds with projecting stone cills.

The principal elevation faces west. The three-bay house at the left contains a central replacement entrance door with a window to its left. Two pitched wall-head dormer windows light the attic storey; the left dormer features wrought iron finial detail centred with the letter 'S'. The right bay is blank. A single-storey west wing (former stable block) abuts the coach house. This section displays a segmental-headed coach arch, a square-headed timber sheeted door with transom light, and three square-headed loophole openings at attic level. The left (north) gable is abutted by a single-storey extension built circa 1995, forming a courtyard housing block to the north. Its exposed section contains two attic windows flanking a central chimneystack.

The rear (east) elevation is partly abutted by a single-storey extension. The exposed section to the right contains two original timber sliding sashes at ground floor level, each protected by cast-iron bars, and two pitched wall-head dormers to the attic. The right dormer contains a replacement metal casement window with partially blocked opening, suggesting it originally held a timber sheeted loft door. The central dormer has paired windows, and a third wall-head dormer at the left features a flat roof. Various square-headed ventilation openings occur at ground and attic levels.

The right (south) gable contains a blocked door opening and a window at the left, with two first-floor windows; the left window is diminished in size and retains an original timber top-hung casement. A single-storey lean-to extension built circa 1995 is attached to the east, with an asbestos tiled lean-to roof, smooth rendered walling, and replacement uPVC windows. Its east elevation contains a replacement door at the right and a window at the left; the left cheek is blank, the right cheek contains two windows (left diminished).

The single-storey west wing (former stable block) built circa 1875 is detailed as the main house. Original door and window openings have been largely altered. The south elevation originally comprised three square-headed door openings: that at the left has been blocked; two at the right are now half blocked and replaced with two uPVC windows. The original carriage arch at the right has been entirely blocked and now contains two replacement timber casement windows, though arch timbers remain visible.

The house and west wing are surrounded by a cobbled perimeter. The north gable has been extended to provide a housing courtyard accessed through original entrance piers, incorporating the renovated west wing. The house is enclosed to the west by high squared-and-snecked rubble walling. Access is through replacement cast-metal gates supported on square-plan roughly coursed sandstone piers with pyramidal coping.
