Redhill House, 15 Bottier Road, Dromore, Co.Antrim, BT25 1RN

Redhill House is a detached three-bay two-storey rendered farmhouse built circa 1850, set within its own landscaped grounds on a large farm holding to the west of Bottier Road in Dromore. The building is rectangular on plan, facing east, with a three-bay two-storey return forming an overall L-plan. To the rear yard stands a U-plan range of two-storey arcaded rendered outbuildings, built circa 1930.

The house has a hipped natural slate roof with black clay ridge tiles to the apex and rolled lead ridges to the remainder. There are a pair of rendered chimneystacks with terracotta pots, and a further rendered stack to the return. Cast-iron rainwater goods are mounted on iron drive-through brackets.

The walls are painted with ruled-and-lined lime render with rusticated quoins. Window openings are square-headed with painted stone sills and contain 6/6 timber sash windows without horns and some cylinder glass. The three-bay symmetrical front east elevation features a central elliptical-headed door opening with a replacement hardwood panelled door, sidelights and fanlight inserted circa 1980, opening onto concrete steps to a front bitumac area. The south side elevation, running flush to the rear return, forms a five-bay elevation with a central elliptical-headed door opening containing a replacement timber panelled door, sidelights and fanlight inserted circa 1990.

The cement rendered rear elevation is abutted by the return, which has a single round-arched window opening to the stairhall containing an Art Nouveau style stained glass window. A flat-roofed extension was added to the rear elevation circa 1980. The two-bay two-storey north side elevation is abutted by a tall rendered screen wall containing an elliptical-headed carriage arch opening into the rear yard. The yard is enclosed by the U-plan range of cement rendered outbuildings with a series of elliptical-arched openings, some now closed, pitched natural slate roofs, steel casement windows and vertically-sheeted timber doors with first floor loading bays.

The house was built within the Clanwilliam Estate and first appears on the 1858 Ordnance Survey map with two oblong outbuildings creating an open-ended courtyard. Between 1867 and 1929, James Agnew is identified as the occupier, with the house valued at £15 and associated land at £40. The Agnews added further outbuildings to the rear, fully enclosing the courtyard as shown on the 1903 Ordnance Survey map, which also named the building Redhill House. The house remained in the Agnew name until John McClelland took tenancy in 1914, followed by Moses Patterson in 1921. Valuations from 1933 to 1957 record Joshua Alex Trimble as tenant, who appealed the first revaluation, describing it as situated "in a backward country place not convenient to town or bus". Following an inspection, the valuer noted it was an "Old farm house…not a superior farmhouse", and the value was subsequently reduced from £69 to £63. At the time of survey in 2010, the dwelling was still operating as a farmhouse under the same family name. The house retains many characteristic mid to late nineteenth-century elements including its 6/6 timber sash windows and ruled-and-lined rendered walls. Despite the loss of its original door case, its plain but well-proportioned façade and rural setting add to the architectural interest of the locality.
