The Old Rectory, 17 Dunderg Road, Macosquin, Coleraine, Co. Londonderry, BT51 4PN

The Old Rectory is a symmetrical three-bay, three-storey-over-basement rendered former rectory built around 1780, situated on the south side of Dunderg Road in Macosquin. The building has a rectangular plan with a flat-roof single-storey projecting porch to the front and a two-storey-over-basement extension to the southwest. The southwest gable is abutted by a two-storey rendered servant's block. The pitched natural slate roof has red-brick chimneystacks to the gables. Plastic rainwater goods run along the projecting eaves, whilst cast-iron ogee rainwater goods with hopper and downpipes serve the porch. The walling is ruled-and-lined cement render with a rendered string-course between the basement and first floor of the porch.

Windows throughout are timber sash with 6/6 glazing at upper floors (not all with horns) in simple painted rendered reveals with projecting painted sandstone sills; 6/3 sash windows to the second floor; and 6/3 and 3/3 sash windows to the basement. The principal elevation faces northwest and is symmetrically arranged about a later central projecting porch. Three windows are positioned wide at the upper floors, with a window to either side of the porch at ground floor level. The porch opens to the northeast, accessed by a set of eight original sandstone steps with a modern metal handrail. A replacement six-panel timber door with brass door furniture sits within a deep round-headed recess. The porch is lit to the southwest by a 6/6 window and to the northwest by a bipartite 6/6 timber window. The basement of the porch is lit to the southwest by a 2/2 fixed timber window. The extension to the right is two windows wide at each floor. The northeast gable is blank. The southeast elevation has five evenly-spaced windows at each floor with metal bars to the basement windows. To the right of centre at ground floor is a set of replacement timber steps. The extension to the left is two windows wide at each floor. The southwest gable is abutted by the extension, which has a 6/3 window to the first floor left of centre.

The building sits on approximately an acre of mature land. Access from Dunderg Road to the northwest is via a gravelled driveway flanked by curved ruled-and-lined entrance walls with square stone piers having corniced caps and supporting replacement cast-iron gates. The site is bounded to Dunderg Road at the northwest by a coursed rock-faced stone wall with coping topped by metal railings (taken from Terrace Row Presbyterian Church); to the north is a modern timber gate on tall red-brick piers with pointed concrete caps. The southern boundary, adjoining the three-span rubblestone Macosquin bridge, is marked by a low rubblestone wall. The entrance leads to an informal yard at the southwest side of the house.

Adjoining the southwest gable is a two-storey roughcast rendered servant's block with rendered chimneystacks and plastic rainwater goods. It is enclosed with rendered walls and accessed via a round-headed cast-iron gate. The northwest elevation of the servant's block contains 6/3 timber sash windows in simple rendered reveals with projecting stone sills, with an 8/4 sash to the ground floor right, and two timber-sheeted doors at ground floor in simple rendered reveals. The southeast elevation shows exposed areas of rubblestone and brickwork and contains replacement fixed timber windows at ground and first floor levels. The interior is plain with a partially quarry tiled floor and quarter-turn timber stairs to the former kitchen. The servant's block is abutted at the southwest by a single-storey slated render outbuilding with 4/4 timber sash windows and timber-sheeted doors in simple painted reveals. The southeast elevation has two bipartite round-headed windows with projecting stone sills and two slender red-brick vents. The southwest elevation contains a window as described at the southeast. The outbuilding interior comprises one large room with a coved timber-sheeted ceiling; walls are plastered and painted, and floors are timber-boarded and laid with carpet. The northeast wall features a simple open hearth with a projecting chimneybreast.

To the southwest side of the yard is a two-storey roughcast rendered slated stable-block with a square-headed carriage-arch entrance containing timber-sheeted doors to the southwest elevation. The first floor has 6/3 timber sash windows and a timber-sheeted loading door; the ground floor has 6/6 sash windows and a replacement timber-sheeted door. The northeast elevation has a timber-sheeted door on a rubblestone and concrete plinth with steps to the first floor left; the southeast gable has windows at ground and first floor. The interior has cobbled flooring and timber partitions to stalls with metal rods, slated tack room, and a cobbled stone floor to the carriage room.

A large garden to the south contains a variety of mature trees and plantings. An original wall to the northeast gable encloses a paved patio area with original cast-iron gates on polygonal cast-iron piers.
