On behalf of the Stiftung Preußischer Kulturbesitz (Prussian Cultural Heritage Foundation), the Federal Office for Building and Regional Planning had invited fourteen international architectural firms to a restricted competition for the comprehensive and landmark-conform repair and restructuring of the Potsdamer Straße branch of the Staatsbibliothek zu Berlin (Berlin State Library), in which the architects von Gerkan, Marg und Partners (gmp) were awarded first prize for their design. The jury saw it as a strength of the design that additional space is gained by expanding the areas that are freely accessible to the public – thereby doing equal justice to Scharoun’s original concept and the demands of a contemporary, open library. The Potsdamer Straße branch of the Staatsbibliothek zu Berlin is located in Berlin’s Tiergarten district. As part of Berlin’s Kulturforum, the so-called Bücherschiff, or “ship of books,” was built from 1967 to 1978 according to plans by the architect Hans Scharoun, with decisive input from his employee Edgar Wisniewski. With its significant holdings of scholarly and scientific literature and its valuable collections, the research library has national and international significance far beyond Berlin’s borders. The building is protected by landmark status and is considered an icon of postwar modernism. The Berliner Philharmonie is another prominent building by Hans Scharoun in the immediate vicinity, also on the Kulturforum.
The redesigned building will be barrier-free. The lobby will be reorganized, and the former open-plan office in the eastern part of the building will be expanded into a publicly accessible area. Next to the new entrance at the northeast corner of the lobby, directly opposite Marlene-Dietrich-Platz, will be a cafeteria with 140 seats; south-facing reading terraces with views of an expanse of water located there establish fluid transitions between inside and outside. This opening out to the city is a response to the present-day urban conditions. The ground floor is also further enlivened by the placement of fixed and movable furniture that revives the building’s original spatial concept. The lobby will be expanded to include an exhibition from the collections. In addition to the conventional reading room and the rooms for group study, new event spaces, workshop areas, and informal work islands offer diversified spatial options.
