The church was originally built in 1886–87 as a chapel for the seaside health resort of Nordanskär, in the Kalix archipelago. After the resort fell into disuse and stood empty for some years, the chapel was dismantled and re-erected inland at Björkfors in 1944. It was consecrated as Björkfors kyrka on 14 October 1945 by Bishop Bengt Jonzon, giving the building a second life far from its original coastal setting.
Constructed from horizontal log timber, the church has a rectangular nave with a five-sided chancel at the east end and a tower at the west. A sacristy is attached on the north side. The exterior walls are clad in white-painted timber panelling and pierced by pointed, Gothic-style windows, while the whole building is topped with a metal-clad saddle roof.
Inside, the ceiling is arranged with a higher central vault decorated with trefoil (three-lobed) ribbing, flanked by lower side aisles separated by slender pillars — a modest but carefully detailed piece of church carpentry. The chancel is decorated with wall paintings by the artist Alvar Granström, adding a distinctive decorative focus to the east end.
According to one source, the church is today run by a foundation rather than directly by the parish, though details of this arrangement are not further described in the material available.
