Where the side walls are plain rendered masonry punctuated by pointed window openings with hood mouldings and pinnacled buttresses between them, the gable facing the road is a different proposition entirely: a central breakfront rises to a tower with a belfry and small spire, flanked by pointed niches and narrow lancet windows arranged with real compositional care. The whole facade is covered in carvings, the work of a local sculptor named Charles O'Connell, and the effect is of a front elevation that has been given considerably more attention than the budget or scale of the building would ordinarily justify.

An inscribed stone set into the facade records the circumstances plainly: the chapel was rebuilt in 1833 under the direction of the Reverend John Barry, and the site itself was donated by a man named Nicholas Leader. The date places the building firmly within the period of Catholic Emancipation, when newly confident Catholic congregations across Ireland began investing in permanent, expressive church architecture after generations of legal restriction. The coursed ashlar limestone of the southwest and southeast walls, ashlar meaning carefully cut and laid stone rather than rough rubble, speaks to that ambition. An apse, the semicircular or polygonal extension typically housing the altar end, was added to the northeast. The church bears a close resemblance to Dernagree church nearby, which suggests O'Connell or the same architectural sensibility was at work in the area more broadly.
