Lisnastream House, 32 Lisnastream Road, Lisburn, County Antrim, BT27 5JJ

Lisnastream House is a symmetrical detached three-bay two-storey redbrick house built around 1900, facing east, with an L-shaped plan that incorporates a multi-bay two-storey rear wing built around 1800. The house stands on a large working farm on the southwest side of Lisnastream Road, accessed via a long bitumac avenue that opens into a bitumac yard to the north side of the house. The yard is lined with lofted outbuildings of varying dates. A single-storey gate lodge with a hipped natural slate roof stands at the road end.

The main house has a hipped natural slate roof with roll-moulded terracotta ridge tiles and profiled redbrick chimneystacks with terracotta pots. Cast-iron rainwater goods sit beneath overhanging eaves with exposed rafter feet. The walling is redbrick laid in Flemish bond with a projecting redbrick plinth course and decorative moulded brick courses at sill and impost levels to both floors. Windows feature segmental-headed openings with stone sills and single-pane timber sash windows with ogee horns; some retain historic glass.

The symmetrical three-bay two-storey front east elevation displays paired window openings to the ground floor and a central segmental-headed door opening with terracotta hood moulding. The original timber doorcase comprises a flat-panelled timber door flanked by a pair of bipartite sidelights with leaded coloured glazing and a tripartite overlight, opening onto a concrete paved platform with steps. The single-bay two-storey south elevation is abutted by a single-storey three-sided canted bay with a hidden roof behind moulded coping. A further single-bay two-storey recessed section has paired windows to each floor; those to the first floor feature decorative leaded Art Nouveau glazing. The rear lower two-storey rendered wing has a hipped natural slate roof and two redbrick chimneystacks with cast-iron rainwater goods. The north side elevation has horizontally-glazed 2/2 timber sash windows with a flight of stone steps to the west end section, while the south elevation is abutted by a modern conservatory and largely glazed with replacement steel or hardwood casement windows.

The gate lodge is a single-storey building with a hipped natural slate roof, terracotta ridge tiles, a redbrick chimneystack, and cast-iron rainwater goods. Its walls are finished in flint-dash render with replacement timber windows and door.

The earlier two-storey rear wing of the house first appears on the first edition Ordnance Survey map of 1833, depicted as an oblong building with two large outbuildings to its north and several smaller offices. By 1861, Griffith's Valuation records show the house and outbuildings were valued at £10 and let to William Graham by the Marquis of Downshire. The townland of Lisnastream was occupied by members of the Graham family from at least the end of the 18th century; a William Graham was recorded as a tenant in 1796, and during the 1798 Rebellion, Wolsey Graham of Lisnastream was noted as a minor leader of the uprising in the area south of Lisburn before being apprehended. However, no evidence links these earlier figures to Lisnastream House specifically. The gate lodge first appears on the second edition Ordnance Survey of 1858 as a square building at the end of the road to the house, and was originally constructed by the Graham family around 1840 as a modest two-roomed single-storey lodge with a hipped roof.

Field research suggests the two-storey redbrick house was added to the earlier wing around 1900; the fourth edition Ordnance Survey map records that the new house had been constructed by 1919–20. The farm buildings situated to the north and west of the house were constructed between 1858 and 1919–20, when they first appear on the maps. The Graham family had vacated Lisnastream House by the beginning of the 20th century, though the identity of subsequent occupants is unknown. The farm continues in operation and the house remains occupied; the gate lodge currently lies vacant.
