Glengeen Lodge, 61 Killyfuddy Road, Trillick, Omagh, BT78 3PN

Glengelen Lodge is a detached symmetrical three-bay two-storey farmhouse built c.1860, located on the south side of Killyfuddy Road, Trillick, on an elevated site within the rural landscape. The house was under construction in 1864, designed by architect Fitzgibbon Louch of Sackville Street, Londonderry, and built by contractor George Armstrong of Brookborough. Contemporary press accounts describe it as "a handsome mansion with extensive offices" in the Italian style.

The house is rectangular on plan with a central single-storey entrance porch to the front (east) and a central two-storey return to the rear. The roof is hipped natural slate with lead-capped ridge, fitted with two smooth-rendered corbelled chimneystacks with clay pots and a third to the rear. Deep overhanging eaves are supported by original joinery; replacement aluminium rainwater goods have been installed throughout. The walls are ruled-and-lined rendered with droved finish, featuring projecting quoins over a projecting chamfered plinth.

The principal east elevation is abutted at the centre by a square-plan entrance porch with flat roof and sandstone ashlar walls with pilasters to the corners supporting a moulded cornice. The porch contains replacement rainwater goods and is accessed by two stone steps. Two replacement four-panelled doors with segmental-headed fanlights are set into the cheeks of the porch. The main façade displays two windows on either side of the porch at ground level and five windows at first floor. Windows are square-headed 1/1 timber sliding sashes with ruled-and-lined voussoirs and droved finish projecting cills; first floor windows are slightly diminished in height.

The east elevation contains a single segmental-headed 1/1 timber sliding sash window with margin lights, surmounted by a crested keystone bearing a lion rampant motif and a banner inscribed 'AD/ASTRA/SEQUOR'. Both the left gable (south) and right gable (north) contain two windows at each floor, detailed identically. The rear elevation is abutted at the centre by a two-storey return with flat roof; the exposed section to the left contains a dipartite 1/1 timber sliding sash at ground floor and two windows at first floor, while the exposed section to the right has a chimneystack with two windows at ground floor (the left window narrower) and a single window at first floor. The west elevation contains a single square 2/2 timber sliding sash at each floor, with a timber-sheeted door in sandstone surround set into the left cheek; the right cheek is blank.

The house retains its original plan-form and proportions. The two-storey return is detailed as the main block with flat roof and replacement aluminium rainwater goods.

The house is set within a formally arranged quadrangular farmyard, with well-constructed outbuildings that together form a good example of a 19th-century working farm. The farmyard is enclosed to the south and east by a high random rubble wall with segmental rubble coping. At the south, square piers with pyramidal caps support replacement cast-metal gates. The north of the farmyard is enclosed by a two-storey block with central double-height bay, pitched natural slate roof with blue-and-black clay ridge tiles, and walls detailed as the house; original timber fenestration is largely intact with 2/2 timber casement windows and timber-sheeted doors. The west side is enclosed by a single-storey outbuilding with corrugated metal roof and doors. Further outbuildings to the west include one detailed as the formally arranged farmyard outbuilding to the north, with exposed random rubble walling and timber fenestration intact.

According to the Annual Revision Records, in 1877 the occupier was William Brien, with the Tottenham family as lessors. This arrangement continued until 1918, when the Allinghams became occupiers and held the property in fee. The buildings were valued at £29 15 shillings throughout the revision period (1860–1923). In March 1922, the property was the scene of the fatal shooting of a special constable employed on the estate.
