The church was designed by the architect Georg Rudner and built in brick, with a rectangular plan and a steeply pitched roof covered in copper. A separate, lower parish wing is joined to the main church building.
Inside, the brick walls are painted white and the floor is also laid in brick, giving the interior a plain, restrained character typical of churches from this period. The ceiling is lined with untreated timber panelling, and the visible laminated wood beams supporting the roof are a notable structural and visual feature of the church room.
A freestanding wooden bell tower, roofed with wood shingles, stands apart from the main church building, a common arrangement in Swedish church architecture that distinguishes bell-housing from the principal place of worship.
As a relatively modern parish church, Obbola kyrka does not carry the centuries of accumulated history associated with many older Swedish churches, but its architecture reflects the functional, materially honest style favoured in Swedish ecclesiastical building of the 1960s.
