What makes this ruin quietly worth attention is the precision still visible in its stonework, despite the vegetation and decay. The building is modest in scale, roughly fourteen and a half metres east to west and just over seven metres north to south, yet it retains a set of architectural details that suggest it was once finished with some care.

The most distinctive feature is the window in the east gable: a single ogee-headed light set within a splayed embrasure and pointed arch. An ogee arch, characterised by its double curve, one concave and one convex, is a form associated with late medieval ecclesiastical building, and its presence here hints at a period of construction or refurbishment somewhere in that era. The doorway in the south wall also has a pointed arch, and four of its stones are punch dressed and chamfered on the exterior, meaning they were worked with a tool to give a slightly textured face, then cut at an angle along the edges. The south wall carries a single-light window near its east end, and the west gable, standing to a height of 5.3 metres, is plain and unornamented. Inside the north wall, three niches are set about 1.8 metres above ground level; one of them has a corresponding niche directly opposite on the south wall. The function of such paired niches is not always clear, though they sometimes held liturgical objects or lamps.
