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

10 Main Street is a Tudoresque double-fronted two-storey house with large gabled half dormers and tall prominent chimney stacks. It was originally the smithy in a broken terrace of former estate workers' cottages built around 1840 for workers on the Forde estate, replacing modest single-storey cottages recorded in the 1836 valuation. The original grouping contained eight small dwellings, a smithy and a store.

The building is located on the south side of Main Street near the centre of Seaforde village, set back behind an open lawn with enclosed gardens to the rear. The north-facing front façade is asymmetrical and rendered with paint finish. To the left of centre is a timber-sheeted door. Immediately to its left is a casement window with four vertically-arranged panes to each light. Both door and window sit within a segmental arch-headed recess, which was originally the doorway to the forge. To the right is a larger window of similar style. The first floor has two much smaller casement windows within the large gabled half dormers, matching the style of the ground floor windows. The gabled roof is covered in natural slate with two Velux windows to the rear. A large chimney stack to the east, shared with number 12, has three tall pots positioned in diamond formation. Metal rainwater goods are present throughout.

The rear elevation has a timber-sheeted door with a casement window either side (the left one being larger), and a gabled half dormer with window to the first floor left.

By the mid-twentieth century the buildings had gradually become vacant and fallen into disrepair, with the smithy virtually derelict by 1970. By the mid-1970s the entire grouping had been acquired by Hearth Housing Trust and underwent complete renovation in 1983–84. During this work each pair of houses was combined to form four larger properties, while the smithy and store were both converted into separate dwellings. Redundant doorways to the front were converted to small windows, archways to the former store and smithy were fitted with conventional house doors, and new large gables were added to the rear of all houses.
