Glenmore Cottage, 57 Trassey Road, Clonachullion, Newcastle, County Down, BT33 0QB

Glenmore Cottage is a mildly picturesque one and a half storey gabled house with half dormers, located in a slight hollow to the north-west side of Trassey Road, approximately 4.5 miles west of Newcastle in County Down. The building assumed its present appearance around 1912 when the roof was raised.

The north-facing front façade is asymmetrical. To the left stands a small single storey gabled porch with a four-panelled timber front door and heavy barge boards with finial. To the left of the porch is a small 2 over 2 sash window with decorative painted surround, with a further two similar windows to the right of the porch. The first floor features four almost evenly spaced gabled half dormers, each with sash windows and painted surrounds. The dormer gables have heavy barge boards and small wooden finials matching the porch detailing. A painted plaque inscribed "Glenmore Cottage" is positioned to the right of the dormer above the front door. The far left of the façade merges with a gabled garage featuring a decorative barge board and painted timber sheeted gable. To the right, a two storey outbuilding with stone steps leading to a first floor timber sheeted door adjoins the main structure; this outbuilding was raised in height so its ridge line coincides with that of the main house.

The west gable contains a small first floor window opening without frame, and a plain timber door to the left of centre at ground floor level. The south rear elevation shows a large window opening with modern steel frame on the first floor of the outbuilding, and to the right a small single storey lean-to extension with a frameless south-facing window opening and plain sheeted door to the west. A 2 over 2 sash window sits immediately to the left of the extension.

The main roof is finished in natural slate with parapets to the gables. Three evenly spaced yellow brick chimney stacks with decorative pots project from the roof. The front north wall is finished in lined render; the remaining walls are rubble finished. Most galvanised rainwater goods are now missing. Two circular stone gate posts with cut stone and precisely moulded circular caps mark the road frontage; the date "1903" is inscribed on one post.

A house has occupied this site since at least 1834, as evidenced by Ordnance Survey mapping. The valuation returns of 1863 record Jane Edgar as occupant. Around 1912, both the main house and attached outbuilding were raised in height by the present owner's grandfather, giving the building its current appearance. The building was last occupied in the 1980s. A modern dwelling stands immediately to the north.
