Plans for a church at Slagnäs date back to 1950, when a chapel foundation was formed to make the project possible, with drawings following a few years later. Although villagers largely agreed on the need for a church, they disagreed sharply over where it and its churchyard should stand. The site eventually chosen was opposite the local football pitch and dance floor, a neighbour some felt was less than ideal. After lengthy discussion among municipal and church officials and residents, building went ahead. Master builder Sigurd Ejederud of Stensele was contracted to erect the church, with timber supplied by the chapel foundation and much of the labour provided by volunteer villagers. The architect was Bo Grefberg of Stockholm.
The church was consecrated on 3 August 1958, with Bishop Ivar Hyllander, provost Oreland and the parish's own priest, Alvar Boström, among those taking part alongside churchwardens and a large gathering of parishioners. Demand exceeded expectations: the 300 seats prepared for the occasion proved too few, and many attendees had to stand.
Architecturally, the church is simple and functional in style. It has a rectangular plan and a hipped roof covered in shingle, with exterior walls clad in horizontal white-painted timber panelling. Inside, the walls are finished with lightly stained wood panelling, and the ceiling is an open-trussed, stained pine construction. The wooden floor holds fixed pews arranged in open sections, and the chancel features a white-painted niche housing the altar. An organ by the Swedish organ builder Grönlund stands on the gallery at the rear of the church. A separate bell tower, clad in red-painted timber, stands apart from the main building; it was inaugurated in November 1958, at which point the parish mortuary also came into use.
