Bäckby was planned from the outset as a large new suburb, intended to house around 12,000 people during the first half of the 1970s. A church was included in the plans from the start, positioned next to the new shopping centre, though building work meant it was not consecrated until 1 September 1974, by Bishop Sven Silén. The architect responsible for the church, and for much of the surrounding centre, was Olle Stål.
The congregation's cooperation with EFS began in 1967, after a fire destroyed the EFS mission house in Västerås. Offered space to continue their work in the nearby Mikaelikyrkan, the two groups began working more closely together, eventually deciding to build Bäckbykyrkan as a joint venture. The arrangement proved successful, and the building was extended twice, in 1980 and again in 1996, to provide additional parish facilities.
Visitors approach through the lower parish rooms and shop-lined square before reaching the church hall itself, which rises with a sloping roof to the north. The white-panelled exterior is marked by a dark, angular freestanding bell tower built from glue-laminated timber, and by two copper crosses on the hall's façades. Inside, the walls and ceiling are lined with timber panelling, with exposed laminated beams supporting the roof and a whitewashed wall behind the chancel. The chancel is raised a few steps above the body of the church, with a plain pulpit to one side and the organ to the other; a simple wooden altar, marked by a crystal cross, stands centrally behind a right-angled altar rail. Fixed pine pews seat around 175 people.//
