The main building materials in the church are copper, concrete and rock. The dome is built of copper both on the inside and on the outside. Also the gallery wall and other minor details are clad with copper.

The interiors of the church - in red, purple and grey observe the colour tones of granite, Finland's most common type of rock. The church floor is polished concrete, and the pulpit is made of reinforced concrete. The pews are made of birch wood. The cross on the altar, baptismal font and votive candle reck have been forged by artist Kauko Moisio.

The church hall textiles have been designed by textile artist Tellervo Strömmer, and the green plantings in the Rock Garden on top of the hill have been designed by garden architect Erik Sommerschield. The stone wall encircling the church has been assembled with rock excavated on site.
