4 Church Street, Greyabbey, Newtownards, Co. Down, BT22 2NQ

4 Church Street is a plain two-storey terrace house of possible pre-1834 construction, situated on the eastern side of Church Street in Greyabbey. It includes a single-storey section to the south-east which formerly served as a blacksmith's forge.

The entire front facade and gable are finished in rough-cast render with plain quoins, a tall plinth, and an eaves course. The roofs are pitched and covered with a mixture of mineral fibre cement and asbestos cement slates, particularly to the rear elevation of the main roof. Three brick chimney stacks rise from the main roof, and cast iron rain-water goods are present.

The front, south-west elevation is asymmetrical, with a left-of-centre doorway positioned slightly above pavement level and accessed via three stone steps. The door is plain timber-sheeted, set within a smooth cement render surround. A sash window with Georgian panes and smooth cement render surround stands to the left of the door, with two further similar windows to the right. Five matching windows occupy the first floor, positioned directly above the ground-floor openings. The south-east gable features a single-storey section with two windows of slightly differing heights, also with Georgian panes. The window to the right of this section was formerly a doorway to the blacksmith's forge until approximately 1987. A small roundel window with brick dressings sits at the gable apex of the single-storey section.

To the rear of the main house stands a large two-storey hipped-roof return. A large single-storey outbuilding or greenhouse with a mono-pitch roof is partly attached to the north-east side of the return. To the north-west side of the return, the main house roof extends below eaves level to form a small extension with one rear chimney, enclosing the space between the return and outbuilding and the boundary with the neighbouring property.

The return and rear elevations feature windows and doors of various sizes, with some openings enlarged. Many windows have been reconstructed to resemble sash-and-case windows, all with Georgian-style panes. French doors are present at the rear of the single-storey section. The rear and return are finished in rough-cast render with smooth cement render surrounds to openings and a smooth cement render plinth to the return.

A building is recorded on this site on the Ordnance Survey map of 1834, which likely corresponds to the structure visible today. The single-storey section was formerly used as a blacksmith's forge.
