Polonia: Ampliación del Museo de Arte Moderno de Poznan

A roof top extension by London based architect Claudio Silvestrin to the National Modern Art Museum of Poznan in Poland, providing access to the newly converted into gallery space on the top floor of the museum. The building arrangement expresses the contemporary and future architectures clearly identifying the three construction dates of the museum 1900, 1976 and 2006.
