Shellmouth United Church

• its location on the southern edge of Shellmouth and the building's north-south placement on a large plot with panoramic views of the Assiniboine River valley

Key exterior elements that define the church's restrained Gothic Revival style include:

• the simple rectangular form set beneath a tall, steep, forward-facing gable roof, with a flat-roofed tower centred on the front (north) facade and a small basement entrance porch on the rear
• the orderly fenestration featuring tall rectangular windows with Y-tracery in plain pointed wood arches on the front and side elevations and a multi-paned oculus in the south gable
• the tower fenestration with two pointed windows in the entrance porch, louvered openings near the mid-point and screened openings near the top revealing the still functioning bell
• the unpretentious materials and finishes, including the horizontal wood siding, panelled exterior wood doors, brick chimney, etc.

Key elements that define the church's handcrafted wood interior include:

• the open plan with a small entrance porch, a nave with three sections of pews between two aisles and a low pulpit and choir platform fronted by wood panelling and balustrades
• the modest materials and finishes, including vertical wood boards on the walls, horizontal boards on the high truncated ceiling, the painted wood floor, the double arched nave doors of light-stained horizontal wood panelling, etc.
• furnishings and fixtures such as the light-stained wooden pews, each numbered, a fine oak pump organ and pulpit, iron heating vents, etc.
