6 Hanover Square, Coagh, Cookstown, BT80 0EF

This is a well-proportioned and detailed house built around 1884, larger than its neighbouring Victorian terraced properties. Two-storey canted bays were added in the early twentieth century, which do not significantly detract from its character, though rear alterations are less sympathetic. It remains one of the more significant buildings in Coagh.

The house is an attached two-storey structure of roughly rectangular plan with a two-storey return to the rear (south-east) and a further two-storey extension to the rear (south) built around 2000. A shallow lean-to open car port, timber clad, stands at the south-eastern gable. The building occupies the eastern end of Hanover Square near the junction with Urbal Road.

The front north elevation is three bays wide. The ground floor contains a central timber-panelled door with a rectangular overlight, flanked by two projecting canted bays on either side. Windows throughout are 2/2 timber sliding sash on cut-stone sills. The canted bay roofs are hipped with natural slate. First-floor windows are square-headed 2/2 timber sliding sash on painted cut-stone sills. External walls on the front are rendered and painted, with chamfered quoins at the edges.

The gable-ended east side elevation has no openings, only a large brick chimney at the apex. The west elevation adjoins the adjacent terrace and contains a single small square-headed door opening to the left of the gable, with a matching chimney at the apex. Both side elevations are unpainted.

The rear south elevation is partially obscured by the return and extension and features square-headed timber casement windows at ground and first-floor levels. External walls here are rubble and snecked stone with brick dressings to windows and edges. The pitched roof carries natural slate. Two-storey matching chimneys stand at each gable end, constructed of red clay brick with yellow brick diamond shapes to their centres and yellow brick stringcourses at the top and bottom. Rainwater goods are cast iron.

The two-storey return has square-headed timber casement windows on the west elevation. External walls are unpainted render to the rear south and side east elevations; the west elevation is rubble and snecked stone with brick dressings. The roof is pitched with natural slate, and there is a simple brick chimney to the rear south gable.

The early twenty-first-century extension features square-headed timber casement windows at ground and first-floor levels, with unpainted render walls and a lean-to roof with aluminium rainwater goods.

The house sits back from Hanover Square behind a low rendered wall with painted cut-stone capping, set near the junction with Urbal Road. A small front garden and rear yard with garden complete the setting.

Historically, the site was previously occupied by a pre-1833 low thatched dwelling of one-and-a-half or two storeys, which by 1838 was noted as containing a shop. The present house was built in 1884 by Hugh Stewart. In 1926 the lease was sold to William J. Duff, a member of the local mill-owning family whose factory stood to the south off Urbal Road, and it has remained with his descendants. The canted bays are recorded as having been added early in the twentieth century; the present owner attributes them to William Duff in 1920, though valuation records only list him as occupant from 1926 onwards.
