The sanctuary room is in the form of a transverse square, with the entrance and the altar in opposite corners. The interior can be characterised by a use of natural materials. The aisle is floored with slate slabs, which lead towards and encircle the altar ring. Wood is the dominating material utilised in the interior - on the wall, ceiling and furniture. A cross motif is silhouetted by light that is emitted from the field of windows located behind the altar.
