1 Trummery Lane, Maghaberry, Moira, Craigavon, County Down, BT67 0JN

1 Trummery Lane is a detached asymmetrical two-storey three-bay farmhouse located at the junction of Trummery Lane and Maghaberry Road, south west of HMP Maghaberry. The building originated as a single-storey thatched dwelling before 1830 and was substantially remodelled in Edwardian style after 1911. It has a rectangular plan form with a subservient two-storey return and an adjacent outbuilding.

The house is constructed of exposed random rubble masonry walling with galletting, with red brick surrounds to openings, brick quoins, and chimney stacks. The pitched roof is natural slate with crested terracotta ridge tiles, overhanging eaves with timber soffits, exposed rafter ends, projected purlins to gable ends, and plain bargeboards. Yellow brick chimney stacks feature moulded cornice courses and plain pots. Cast-iron ogee moulded rainwater goods are throughout. Windows are 1/1 timber sliding sash with horns, stone cills, and smooth rendered reveals to jambs and head. The front door comprises 15 panes of timber with modern ironmongery.

The principal elevation faces south and is asymmetrically arranged. An entrance porch dating to around 1965 is positioned right of centre, constructed of red brick in stretcher bond with a gable end, fish-scale slates, terracotta crested ridge tiles, and finial with decorative bargeboards. The front door is located on the right cheek with a stained margin-paned sliding sash window to the gable end; the left cheek is blank. A single window appears to the right with two to the left, with diminished first floor openings directly above. Evidence of a blocked-up door opening is visible between the left-hand windows. The left gable is asymmetrical with single windows to ground and first floor positioned on the left-hand side. The ground floor window surround is distinctly less uniform, suggesting a later insertion, possibly contemporary with the rear return.

The rear elevation is asymmetrically arranged with a two-storey return abutting the right-hand side dating to around 1915. The right cheek of this return has two first floor windows and a large modified opening to the ground floor. The gable end is abutted by a modern flat-roofed extension that wraps around the left cheek (with a window at first floor), infilling the space between the rear of the house and the adjacent outbuilding. Two first floor and a single ground floor window appear left of the return. The right gable is blank.

The house is prominently located on a corner junction adjacent to the main thoroughfare through Maghaberry. Gardens bound the front and rear, with coniferous vegetation to the west. The east side of the site runs parallel to the adjacent secondary road and is bounded by a small parapet wall of smooth rendered masonry surmounted by iron railings and a pedestrian gate. Beyond the road is modern housing. To the rear stands a long single-storey outbuilding of rubble masonry with slated roof, recently converted into accommodation. A rubble masonry wall bounds the north of the site, running parallel to the main road.

The building first appears on the 1832–33 edition of the Ordnance Survey map, depicted as an oblong structure. The Townland Valuation of around the 1830s records that the house and its offices were valued at £4 18s and occupied by Matthew Watson. The valuer described it as a 2b+ structure measuring 46 feet by 19 feet with a height of 11 feet. The rear outbuilding measured 30 feet by 20 feet and was valued at 18 shillings and 5 pence. Watson resided there until 1874, when David Gray acquired the property, valued then at £5 10s. Annual Revisions record that Gray purchased the house from the Hertford Estate in 1895 and occupied it until 1904, when Robert Mayne, a local farmer, took possession. Census records indicate Mayne was resident by 1901 at age 65 with his wife Ann Jane, aged 58, and their five children. The 1901 Census describes the house as a thatched second-class dwelling containing four to six rooms. Mayne had vacated by 1911, when Terence Catney, a 73-year-old Roman Catholic farmer, occupied the house alone until his death in February 1914. The 1911 Census continued to describe it as a thatched dwelling with six rooms. Census records for 1911 indicate the house possessed a stable, cow house, piggery, and fowl house within the rear outbuilding.

The current Edwardian house and rear return were constructed after 1911, first appearing on the fourth edition of the Ordnance Survey map of 1920–21. Following Catney's death in February 1914, the property came into the possession of William Archer, who occupied the farm until the Annual Revisions ended in 1929. Catney's will, dated 11 February 1914, bequeathed the considerable sum of £1,778 19 shillings and 1 penny to John Heaney and Francis Mulholland, employed respectively as a builder and farmer.

The site layout remained unchanged by 1973. In recent years, a single-storey return has been constructed joining the Edwardian return to the rear outbuilding. The south half of the outbuilding has been converted into a kitchen, whilst the north half continues as a storeroom.

Early 20th-century modifications affected the interiors, windows, and roofing. The modern additions to the rear are not particularly sympathetic in detailing and detract from the overall appearance. Although interesting, the building is not considered of special architectural interest and is not suitable for listing.
