16 Tansy Lane, Drumanduff, Ballinderry Upper, Lisburn, County Antrim, BT28 2PX

16 Tansy Lane is a single-storey, three-bay hearth-lobby type vernacular dwelling with adjoining linear outbuildings, predating 1830. It is located at the end of a long lane off Tansy Lane, approximately 1.5 miles northeast of Upper Ballinderry in the townland of Drumanduff.

The building is constructed with rough-cast walling, lime rendered to the rear, and sits beneath a pitched corrugated roof with skews over the right gable. Brick chimneys rise from the structure, and uPVC rainwater goods are fixed to timber fascia boards. The principal elevation faces south and is asymmetrically arranged, with the front entrance located right of centre, flanked by two windows to the left and one to the right. Windows throughout are 2/2 timber sliding sash with horizontal glazing bars and horns. The front door is timber sheeted.

The left gable is abutted by slightly lower linear outbuildings of generally rubble stone construction with corrugated tin roofing and various openings. Further adjoining outbuildings run at right-angles to the north and south, of various styles and quality, added at a later date. The rear elevation is asymmetrically arranged with a single opening to the right and an enlarged centrally located window. A single-storey flat-roofed abutment extends from the right bay across the north face of the outbuildings to the right. The right gable is blank.

The building is in generally poor condition. Although the principal elevation retains its style and proportion, its vernacular character has been compromised by rough-cast cement rendering and flat-roofed additions. The setting has been significantly altered by an adjacent large two-storey modern dwelling. Largely overgrown vegetation surrounds and obscures the cottage on approach, though views across open rural landscape remain visible.

A building approximating to the plan form of the present dwelling is shown on the first edition Ordnance Survey map of 1832. In Griffith's Valuation of 1862, the house is listed as the residence of John Larmour and valued at £1 10 shillings, with over five acres of land attached. The farm was leased from the Marquess of Hertford, later Sir Richard Wallace. The farm remained in the Larmour family until 1874 when it passed to Henry Quigley. By the third edition Ordnance Survey map of 1900-01, the house had been extended by a single-bay outbuilding to the east. The 1901 census indicates the house was thatched at that time and had three rooms, with 72-year-old farmer Henry Quigley resident with his wife Abigail. By 1908 Henry Quigley had died and the house passed to his widow. The house is not identifiable in the 1911 census and may have been vacant at that time.

Ballinderry parish was described in Lewis's 1837 survey as a fertile agricultural area with cottage industry. The area has remained rural, with scattered farms and small settlements. The house is situated within the better arable land of the district, lying between the 100-foot and 300-foot contours. The hearth-lobby type dwelling is prevalent throughout central and south-west Ulster. The whole area experienced population decline during the second half of the nineteenth century when drift began from rural districts into Belfast, though the population began to stabilise around the turn of the twentieth century.

The building does not meet the criteria for listing and there are better examples of vernacular dwellings listed in the area.
