Built between 1935 and 1937, St. Martin's Church was badly damaged during the war. The wooden roof truss above the nave and the false ceiling in the sacristy area were rebuilt in 1950. The church has a gross floor area of 2,327 m² and consists of a nave and aisle, an extension and a tower building. The building has a full basement and originally served as an air raid shelter.
The construction measures include the interior conversion and the technical modernization of the listed church. A community hall, various group rooms, an exercise room as well as administration and storage areas will be created for community life and the diverse church activities. A bistro area will also be set up as a meeting place.
To create and enlarge door openings in the basement, load-bearing walls are removed and supports for the vertical loads are created in the form of steel girders. The ribbed ceiling above the former confirmation hall was constructed in deviation from the planning and the rules of technology applicable at the time of construction and will therefore be demolished. The reconstruction of the gallery, including an extension, will be carried out in steel construction. It will be supported by wall-like lattice girders, which will be cantilevered between the load-bearing interior wall in the basement and the gable wall. This avoids interfering with the existing supporting structure of the basement.
