The main section of the church measures 58 by 30 feet (17.7 by 9.1 m), with its longer axis running west-east parallel to 51st Avenue.
The facade is composed of cement asbestos shingles over wood shingles.
The northern and southern facades each contain three round-arched window openings outfitted with lancet windows, while the eastern facade contains two round-arched window openings.
The front entrance is on the eastern facade, facing Broadway, and is composed of double doors underneath a circular window measuring about 5 feet (1.5 m) in diameter.
The roof is a gable roof with overhanging eaves supported by flared brackets.
A brick chimney is located above the western section of the roof.

The annex to the west measures 25 by 15 feet (7.6 by 4.6 m).
As with the main portion of the building, it has a gable roof with eaves overhanging the northern and southern facades.
There are two lancet windows on the northern, western, and southern facades, as well as a semicircular window beneath the gable on the western facade.
However, the material used in the facade is slightly different, with cement asbestos shingles on the northern and western facades, and plywood on the southern facade; the brackets beneath the roof are not flared.
A basement is located underneath the annex.
The western annex occupies the site of the church's former tower, which was topped by a steeple and a weather vane.
