The church center consists of roof surfaces of different heights. The façade, made of washed waterstruck bricks, gives the building a uniform appearance, which also suggests that the buildings represent the union of the two churches (St. Peter and St. James). It is also intended to stand for New Architecture in Karlsruhe, as the building's function is at the forefront. The church center received an award for "exemplary building" from the Baden-Württemberg Chamber of Architects in 2018.
