The Church building is made of clinker bricks. “Clinker refers not to a style, but to a construction material that proved quite popular in Edmonton. Clinker bricks were bricks that were overfired when being made. The excessive temperatures caused minerals in the clay to form a natural glaze, with hues of red, green, yellow, and purple. Some bricks also fused together in clumps, adding to their unpredictable appearance. Unlike elsewhere in Alberta, builders in Edmonton came to value these unique bricks for the aesthetic quality they provided.” (Taken from the Edmonton Historical Board)
