The Lodge, 21 Main Street, Seaforde (Seaforde Demesne), Downpatrick, County Down, BT30 8PA

The Lodge is a single-storey over basement Regency style villa with an overhanging hipped roof and stylised classical porch. It is believed to have been built c.1837 as a two-storey structure, but was reduced to a single storey—and probably extended—c.1840, with a possible further extension c.1860. Built as an agent's residence, the property is located within spacious grounds on the south side of Seaforde Demesne, approached by a drive opening from the north of Main Street, to the northwest of Seaforde village.

The front elevation faces roughly south and is asymmetrical. To the right of centre is a small stylised classical projecting porch reached via three stone steps. The porch contains a six-panel timber door with a simple rectangular fanlight and moulded surround. The corners of the porch are framed with simple stylised moulded pilasters. The porch gable has an overhanging roof and a gable tympanum supported on paired brackets. Each of the east and west faces of the porch has a centred semicircular arch-headed window with timber sash frame in Georgian panes (9/6). Either side of the porch is a window with Georgian paned timber sash frame (6/6), each with moulded surrounds whose side panels drop slightly to rest on a broad string course. The porch and these windows sit within a projecting bay with a shallow hipped roof, framed with raised plain pilaster-like panels. To the left of the bay are two windows as before; to the right is a single similar window. The entire front elevation sits over a basement ravine, with the porch acting as a bridge into the house. Basement level windows sit directly beneath each upper level window, each with a timber sash frame (6/3). The ends of the elevation are finished with raised plain pilaster-like panels.

The west elevation is blank at upper level, with two plain doors to the right side of the ground level. The left side of the ground level is abutted by a single-storey outbuilding. The east elevation has a centrally positioned canted bay with windows on each face. The north elevation is two storeys with a wide bay projecting forward slightly left of centre, and a small two-storey canted bay to the left. The ground floor of the main bay has a glazed and panelled door, with windows to each side face featuring six-pane fixed light timber frames. At first floor, each face has a timber sash window (6/6, with those to outer sides much narrower). To the right of the bay on the ground floor is a timber casement window. Further right is a c.1980s replacement window with top opener above a fixed light; its lower section has been blocked, leaving the old sill in place. Directly above is a timber sash window (6/6). To the left and right of the bay the elevation sets back slightly. To the left is another sash window. To the right is a tall sash window (6/12) lighting the stairwell, deepened in the 1960s and now cutting through a string course. Further right are two ground floor windows with timber sash frames (6/3) and two first floor windows with similar frames (6/6).

The façade is finished in lined render and painted. The roof is hipped and slated with an overhang supported on paired brackets. Four irregularly positioned rendered chimney stacks are present, with matching octagonal pots to three. Cast iron rainwater goods are fitted throughout.

To the west and partly attached to the house is a collection of single-storey outbuildings with a screen wall creating a small courtyard. To the west is a two-storey stable block, rendered with in and out stone dressings to some door openings. The interior of the stable block still retains all original stalls.
