According to the main designer, Architect Sauli Havas, the building has an invisible theme of breaking or decomposition and becoming whole. Surfaces and various parts of the building highlight different transitional lines. The main door is surrounded by a scene in graphic concrete where rocks split apart and the temple's curtain was turn apart. A 100 meter long concrete wall, 6-7 meters high, runs through the L-shaped building.
Walls are designed by Professor Tapani Aartomaa and Architect Sauli Havas with Professor Vesa Nikunen as specialist of symbols.
Using graphic concrete, the walls contain coloured and embrossed pines, christian and medieval historic symbols.
