The building did not begin life as a church at all. It was originally constructed as accommodation for workers, likely connected to the hydroelectric development at Porjus in the early twentieth century. In 1928 the barrack was handed over to the church youth circle in Porjus, and on the initiative of curate Axel Löfqvist it was converted into a place of worship. A further restoration in 1957 gave the interior much of its present appearance.
The church is a rectangular timber building, its outer walls and roof covered in dark brown wooden shingles, giving it a modest, functional appearance that reflects its practical origins. Inside, a wooden floor and fixed pews in enclosed sections lead towards a chancel raised one step above the rest of the room. The ceiling is a coved timber construction, and both walls and ceiling are lined with light brown wood panelling, creating a warm, simple interior in keeping with the building's utilitarian roots.
A short distance east of the church, on a small hill, stands a separate wooden bell tower dating from 1921, older than the church building itself and a reminder that the site was already in some use before the church was established.
Among the church's fittings are a font of hammered granite and a plain, unpainted wooden crucifix hanging above the altar. An oil painting by Syster Marianne depicts Mary with the infant Jesus set against a mountain landscape, a detail that ties the church visually to its northern, Sápmi-adjacent setting.
