12 Main Street, Seaforde, Naghan, Downpatrick, Co Down, BT30 8PA

12 Main Street is a Tudoresque, double-fronted two-storey house with large gabled half dormers and a tall prominent chimney stack. It forms part of a broken terrace of former estate workers' cottages built around 1840 on the south side of Main Street in Seaforde village.

The terrace originally comprised eight small dwellings, a smithy, and a store, built for workers on the Forde estate. These replaced modest single-storey cottages recorded in the 1836 valuation. By the mid-twentieth century, the buildings had gradually become vacant and fallen into disrepair, with the smithy virtually derelict by 1970.

In the mid-1970s, Hearth Housing Trust acquired the entire grouping. A comprehensive renovation took place in 1983-84, during which each pair of houses was amalgamated to form four larger properties, and both the smithy and store were converted into two additional dwellings. Redundant doorways to the front were made into small windows, and new large gables were added to the rear of all houses.

The north-facing front façade is asymmetrical. To the right is a timber-sheeted door within a segmental arch-headed recess, originally the door to the forge. Immediately to its right is a casement window with four vertically arranged panes to each light. To the left is a larger casement window of similar style. On the first floor, within the large gabled half dormers, are two much smaller casement windows matching the ground-floor style. The west gable is blank.

The rear has a timber-sheeted door with a casement window to either side, the right-hand window larger. The first-floor right features a gabled half-dormer with window. The façade is rendered and painted. The gabled roof is covered in natural slate with two Velux windows to the rear. A large chimney stack to the west, shared with No. 10, has three tall pots positioned in diamond formation. Metal rainwater goods are present. The building is set within an open lawn to the front and enclosed gardens to the rear.
