In November 2014, the Bundestag, Germany’s parliament, resolved to assign 200 million euros to the Stiftung Preußischer Kulturbesitz (Prussian Cultural Heritage Foundation) for a new building to show twentieth-century art at the Kulturforum. The new building is needed because for decades it has only been possible to exhibit small selections from the Nationalgalerie's comprehensive collection of twentieth-century art.

The new building will allow several internationally significant art collections to be displayed together permanently for the first time: the Nationalgalerie's collection of twentieth-century art, the Marx and Pietzsch collections, parts of the Marzona collection, which is embedded inthe Staatliche Museen, and works from the Kupferstichkabinett (Museum of Prints and Drawings). They will be shown both on the lower level of the Neue Nationalgalerie and, above all, in the exhibition spaces of the new building.
