The district was built up mainly during the post-war era, and Söderkyrkan is today surrounded by residential buildings typical of the period, constructed mainly during the 1940s and 1950s. The church replaced a building from 1969, a so-called 'vandringskyrka' (wandering church), which was moved to the Lunedet outdoor recreation area.
Söderkyrkan was designed by the architect Janne Feldt from Karlstad. The church forms the centre of a complex, in which the parish hall and other premises for church activities are housed in angled, lower buildings. Externally, the facades are of light brownish-red brick with roofs of light grey sheet metal.
The church hall has an original five-sided floor plan with a deliberate architectural design of light, with daylight entering through a windowed roof lantern. In the main, all the fittings were created by the architect. The chancel wall of the church hall and the wall facing the church square are built of whitewashed brick. Otherwise, the walls of the church hall are clad with white-glazed, veneered wooden panels, which have been divided into fields to break up the large surfaces.
The chancel is dominated by an altarpiece, a triptych with painted and carved wooden reliefs depicting Jesus in Gethsemane, the Revelation, and the Great Commission. The altarpiece was made by Harry W. Svensson in Fägre, near Töreboda. The church's fittings—altar table, pulpit, font, kneeling rail/altar rail and hymn book storage—were designed by the architect Janne Feldt. Light-coloured beech has been used as the material; the design is simple and understated, and all the furniture is movable. The font's basin is of brass.
