The planned design has three defining basic units: the church, the bell tower, and the congregation house, which also contains the pastor's office. Of these, the congregation house and the bell tower were built in the first phase. The architectural concept was to create a pure building radiating simplicity, a “dwelling” of biblical clarity. With its open and transparent yet sheltering architectural design, the congregation house serves as a worthy place for community life. The building consists of a single-storey, cantilevering gabled volume and a bell tower, which is an organic and symbolic part of the ensemble. The timber-clad terrace wedged between the congregation hall and the tower extends the interior community space through a door that can be opened across its full width. The cantilevering roof forms a transition between outside and inside. The facade opening to the south is shaded in summer by the strongly projecting roof, while in winter it lets in the low-angle sunlight. The garden completes this unity. The heating of the energy-efficient, low-energy building is provided by an air-to-water heat pump with surface heating and cooling.
