Hillville, 19 Ballyblack Road, Ballyhaft, Newtownards, Co Down, BT22 2AP

Hillville is an irregularly shaped, roughly 'L'-plan farmhouse situated on a slight rise at the end of a lane off Ballyblack Road, approximately 2 miles southwest of Newtownards, Co Down. The building comprises two distinct sections of different periods and architectural character.

The eastern section, facing onto the lane, is one storey with an attic and displays late Victorian styling, likely dating from the 1880s–1890s. The front elevation is notably decorative, featuring a timber and glazed central double door with sidelights and an elliptical arch fanlight with gothic tracery, all set within an elliptical arched opening. On either side of the doorway is a single sash window with horizontal astragals, set within a segmental arch head and surmounted by a cornice hood on brackets. Directly above the doorway is a pointed arch window with horizontal astragals, positioned within a gabled half dormer with decorative barges and finial.

The northern facade of this section has a similar half dormer with window to the right on the ground floor, though smaller and without the cornice hood and brackets of the front elevation. The southern facade also features a ground floor window matching the front design and a half dormer directly above it.

The western rear section is a two-storey, gabled structure which may date to the 18th century, though this is now difficult to confirm given extensive modernisation. The northern facade contains three modern first-floor windows to the centre and left, with a ground floor single-storey lean-to projection to the left, featuring small and larger modern windows either side of a flat-roofed porch containing a modern glazed door. A further modern window lies to the right of the lean-to. The western gable is blank. The southern facade displays a large single-storey flat-roofed extension to the left with large modern window, another large modern window to the right, a glazed door to the far right, and three modern first-floor windows. An extremely narrow sash window marks the junction between the two sections at the rear of the Victorian portion.

The entire building is finished in lined render. The Victorian eastern section is distinguished by a yellow brick dentilled eaves course, chamfered plinth, and vermiculated quoins. Its roof is hipped, covered with Bangor blue slates and carrying two yellow brick chimney stacks with cast iron rainwater goods. The rear section has a roof partly hipped, partly gabled, also in Bangor blue slates, with one rendered chimney stack and PVC rainwater goods.

Historical evidence from Ordnance Survey mapping indicates a building occupied the site of the present rear section in 1834. The revised map of circa 1860 shows the building much as it stands today, with both sections present, though the eastern portion's late Victorian appearance suggests it may have been renovated or rebuilt after 1860. The current owner in 1998 believed the rear section to be 18th-century in origin. Valuation records from circa 1835 and 1861 are listed among historical sources.
