The building is constructed of Oamaru stone, set on foundations of basalt breccia from Port Chalmers, with details carved by Louis Godfrey, who also did much of the woodcarving in the interior. The use of "cathedral glass", coloured but unfigured glass pending the donation of a pictorial window for the rose window is characteristic of Otago's 19th-century churches, where donors were relatively few reflecting the generally "low church" sentiments of the place. Similar examples can be found in several of Lawson's other churches throughout Otago.
