38 Trassey Road, Clonachullion, Newcastle, County Down, BT33 0QB

This is a two-storey, gabled vernacular house likely built in the mid-19th century. It stands at the end of a long lane rising up Clonachullion Hill, approximately four miles west of Newcastle, County Down. The building is situated on a slope running east to west.

The asymmetrical front façade faces north. A small gabled porch with a modern half-glazed door and scalloped timber fascia is located to the right of the façade. To the left are three evenly spaced openings containing modern two-pane timber windows. Four squat, evenly spaced, sash windows (two panes over two) are positioned on the first floor. The east gable is blank.

The south façade has a single-storey gabled return on the left side; the rest of the south face is blank. The south face of this return has no openings but incorporates an external chimney to the right of the apex. The west face of the return features a modern timber window to the left of centre, while the east face has a plain timber door to the right, alongside a two-pane modern window to the left. A gabled outbuilding with two painted timber doors (the one on the right set at a slightly lower level) adjoins the west gable. An additional, lean-to outbuilding with a corrugated iron roof is situated to the far right. Two small sheds are set well back and to the west of the main house.

The façade is primarily cement rendered, although evidence of earlier harling is visible on the east gable and the porch. The roof is covered in natural slate and includes two rendered chimney stacks, one central and one on the east gable.

A building is depicted on this site in Ordnance Survey maps of 1834 and 1859, potentially corresponding to the current structure. The building's present two-storey appearance may reflect a later 19th or early 20th century raising of the roof. In 1863, William Kane was listed as the occupant, with the building’s assessed rateable value at £2-10-0.
