The church was designed by Nyréns arkitektkontor and consecrated on 19 June 2005 by Bishop Caroline Krook. Built entirely in wood, with a white facade both outside and in, it has a bright, open interior featuring exposed beams and pillars. The nave is arranged crosswise, with the altar set against the long wall rather than at the traditional east end.
Before this building existed, the congregation worshipped in a so-called 'travelling church' or studio church, a prefabricated timber structure designed by the church architect Rolf Bergh. Erected in 1971 on the site of former stables and farm buildings at Viksjö gård, it had earlier stood at Barkarby from 1969 while the medieval parish church at Järfälla was being restored. This temporary building remained in use for over three decades, right up until the Sunday before the new church was consecrated in June 2005.
The altar, font and lectern in the present church were all designed by Nyréns arkitektkontor, giving the interior a unified, contemporary character. The organ, however, has an older history: built by Walter Thür and inaugurated in 1981, it was brought over from the earlier studio church. The bell tower, dating from 1977 and holding two bells, likewise once stood beside the old church before being relocated to the new site.
The church can seat around 250 people, with an adjoining parish hall accommodating a further 70, reflecting its role as a working community church as much as a place of historic pilgrimage.
