Located on the site of an old factory, this archive harbors a major collection of original documents and books of the Evangelical Lutheran Church of Bavaria – including letters written by Martin Luther to the popes and emperors of his day – as well as a restoration workshop and didactic areas. The program is distributed in the three parts that make up the building. First is a large plinth clad with local sandstone, a finish that resonates with the context and with the materials of the adjacent building, a seminary. Over it, on a transparent level, are two intersecting cubes. On a structure of pillars of reinforced concrete, the two prisms hover a meter above the ground floor to form a continuous surface that opens only to take in views of the surroundings, in particular the nearby lake, the Wöhrdersee.

From a constructional point of view, the building’s main point of interest is its ventilated facade, formed by panels of folded copper, 15 millimeters thick, which cover a layer of wool rock insulation 20 centimeters thick and are held up by a metallic subframe anchored to the loadbearing skin.The complex presents varying finishes, with different textures and colors ranging from brownish matte to shiny metal tones, all resulting from the pre-oxidation treatment given to the copper panels.
