The church was built entirely of concrete, an unusual and deliberate choice by Varhelyi, who wanted the building to harmonise with the newly constructed town centre around it. Strikingly, even the font, altar and pulpit are made of concrete, and the architect intentionally avoided decorative flourishes, aiming instead for an interior stripped of what he called architectural refinement, in order to encourage uninterrupted contemplation.
The interior runs east to west, with the chancel at the eastern end. The bell tower is built into the structure itself, and visitors can see the bells from inside the church through glass walls; the sacristy occupies the tower's ground floor.
The building suffered an interior fire in May 1985 and was subsequently restored; climbing plants were later introduced both outside and inside the church as part of its greening.
Locals have given the church the affectionate nickname "Santa Cementa", a wry nod to its uncompromising concrete exterior.
Despite the otherwise austere interior, a few notable furnishings stand out: a large textile hanging on the chancel wall, designed by Anna Lisa Odelqvist-Kruse and made in 1954, an embroidered altar frontal, a rölakan-technique carpet from 1973 by Birgitta Modig laid before the altar, and a set of silver communion vessels supplied in 1962 by silversmith Carl Nyströmer. The mechanical organ, built in 1964 by Åkerman & Lund, has eleven stops.
