Sion Mills Recreation Club, 151 Melmount Road, Sion Mills, Co Tyrone, BT82 9EX

Sion Mills Recreation Club is a detached, symmetrical two-storey building of considerable architectural distinction, built around 1895 as a Working Mens' Institute in the designed industrial village of Sion Mills. Designed by the important architect W. F. Unsworth and built by contractor Joseph Ballantine of Londonderry for the Herdman family, proprietors of the Mills, the building exemplifies Arts and Crafts principles and remains one of the more notable structures within the conservation area.

The rectangular building faces east on the west side of Melmount Road. Its construction combines random coursed rock-faced sandstone ashlar walling to the ground floor and staircase with applied timber framing and pebbledash rendered panels to the upper storey. The pitched roof is covered in terracotta tiles with roll-moulded ridge tiles, sprocketed eaves with exposed rafter feet and timber bargeboards to the gables. Steel rainwater goods are fitted to the rafter feet.

The symmetrical front elevation displays four square-headed window openings to the ground floor with stone relieving arches and timber casement windows with lead-lined timber sills. The first floor features a series of tripartite timber casement windows with leaded glazing and some steel casements. Dominating the centre of the front elevation is a large redbrick chimneystack, laid in Flemish bond, which projects beyond the stone wall as a narrow flue at ground floor level. The stack is corbelled out in redbrick to form a large blind breakfront at first floor level, before narrowing again above the roof. This feature chimneystack is a hallmark of the building's Arts and Crafts character.

The south gable is pebbledash rendered above ground floor and is abutted by an external stone staircase built on a T-plan in random course rock-faced sandstone ashlar with tooled stone ashlar coping and concrete steps. The staircase leads to a single door opening to the first floor with a vertically-sheeted timber door. At ground floor level a round-headed door opening features a voussoired stone arch and vertically-sheeted timber door.

The rear elevation is abutted by a large flat-roofed extension with a decorative single-pitched terracotta tiled canopy. Ten tripartite windows with leaded lights are visible to the first floor, set within a timber-framed wall with continuous timber sill and pebbledash render below. The gable-ended north elevation features a large landscape window opening to both floors with timber casement windows having leaded lights, and displays elaborate timber framing and pebbledash render with overhanging eaves and carved timber barge-board above a ground floor of random coursed rock-faced sandstone ashlar.

The building is set back from the road with a paved front area enclosed by a low rubblestone wall with stacked coping, continued to the north forming the boundary with the adjacent Church. To the centre of the front area is a semi-circular concrete paved area open to the street with low concrete block wall and war memorial stone. To the rear stands a small single-storey gable-fronted structure marked as a Telephone Exchange.

Originally comprising a billiard room on the ground floor and a reading room or library on the first floor, the Institute was built in response to the Herdmans' temperance principles—until 1896, when they lost a court case, there was no public house in Sion Mills village. The provision of recreational facilities was intended to offer improvement and recreation to mill workers without resort to alcohol. An effusive article in The Irish Builder of 1 July 1895 described the newly-opened building as "a thoroughly picturesque work of art". By 1934, the Institute comprised two billiard rooms, with one table on the first floor. The occupiers were subsequently changed to the Sion Mills Amalgamated Sports Club, and it is now known as Sion Mills Recreation Club.

While the interior has lost much of its original appearance, the exterior remains largely intact. The building has significant group value with other listed buildings of similar Arts and Crafts style within Sion Mills and constitutes an important architectural contribution to the conservation area.
