20 Hayes Park, Lurgan Road, Banbridge, Co Down, BT32 4PF

20 Hayes Park is a semi-detached single-bay one-and-a-half-storey house built around 1912 in concrete block, with a two-storey extension added to the east gable around 1970. It was constructed as one of a pair within a cul-de-sac of 28 similar houses designed by William Larmour. The development is located on the east side of Lurgan Road opposite the former Seapatrick Mills and is laid out as a garden village with a winding bitumac road.

The house has a steeply pitched natural slate roof with terracotta ridge tiles and a decorative finial. A shared rendered chimneystack with capstone and terracotta pots is positioned centrally. The building features a single cat-slide dormer to front and rear with exposed timber rafter feet to the overhanging eaves throughout, timber bargeboards, and cast-iron rainwater goods.

The walls are of rock-face moulded concrete block with a projecting concrete plinth course. Window openings are square-headed with flush concrete lintels and sills. The single-bay front elevation displays a tripartite window opening to the ground floor with rock-face moulded concrete mullions and original half-timber sash windows. A central dormer rises above the eaves with a catslide roof and tripartite timber casement window. The west elevation is abutted by the adjoining property. The rear elevation mirrors the front with a matching dormer and a single square-headed window opening to the ground floor. The east side elevation is abutted by the 1970 extension, which is built in rock-face moulded concrete block with square-headed window openings containing timber casement windows. The current front entrance is located on the north elevation of the extension with a flush concrete lintel and surround and a timber panelled door.

The house sits in a cul-de-sac of 28 similar dwellings accessed via a winding bitumac road, with a raised front garden enclosed by a concrete brick wall and a large rear garden.

Hayes Park was built by F W Hayes & Co, proprietors of Seapatrick Spinning Mills, to house their workers in a garden village setting. Numbers 19 and 20 were among the first eight houses constructed, entering valuation records in 1912. The development continued between 1912 and 1919, with additional phases in 1913 and 1914. Originally costing £300 per pair and renting at 3 shillings and sixpence per week, the houses were described as "English-style" and carried a certain status, being intended for foremen rather than ordinary workers. Early photographs show the houses originally had small side porches and separate store and lavatory buildings, most of which have since been replaced or extended. The rural character of the development was emphasised by the absence of roads initially into the site, giving rise to the local saying "Hayes by name and a maze by nature."

William Larmour of Banbridge designed the estate, said to have been inspired by ideas promoted by one of the Barbour ladies of Hilden. The development was influenced by the contemporary garden city movement, which sought to provide spacious, low-density housing surrounded by green spaces for industrial workforces. Seapatrick Mills itself had a longer history: Frederick William Hayes built weaving sheds on glebe land in 1834, later converting the mill to linen thread production as "Royal Irish Linen Threads." His son William Hayes continued the business and initiated earlier phases of workers' housing, including terraces on Kilpike Road around the mid-nineteenth century and management housing on Lurgan Road circa 1865. Milfort Terrace, a red-brick terrace of management houses, was erected around 1890 opposite Seapatrick Rectory, followed by Bannview Terrace, a red-brick workers' housing terrace. The semi-detached dwellings at Seapatrick Villas were built in 1908–9, preceding the Hayes Park development.

The house continues in use as a domestic dwelling. Although the building survives as an early twentieth-century example of suburban design within a paternalistic industrial housing scheme, it has been compromised by alterations and extension and does not represent the best examples of the type.
