After designing the Serralves Museum in the 1990s, the venerable architect Álvaro Siza has created an extension for this Porto institution. For this project, the architect, who won the Pritzker Prize in 1992, added over 4,000 square meters of space, requiring eighteen months of planning and construction. Organized over three floors, this extension dedicates one level to the museum's archives and two others to contemporary art and architecture exhibitions. As a result, the museum gains 50% more exhibition space and 75% more storage space, allowing for new acquisitions. 

This new wing is located in Serralves Park, on the west side of the existing building. The structure is made of reinforced concrete, with an exterior cladding of granite and painted plaster, and inside the building, the galleries feature white walls and oak flooring adorned with marble baseboards.

To mark this expansion, two exhibitions have been planned. The first, "Improbable Anagrams," is a permanent exhibition showcasing the Serralves Foundation's collection spanning more than sixty years. The second, "CAS A.," an acronym for "Coleção Álvaro Siza, Arquivo" (Álvaro Siza Collection, Archive), presents works from the Siza archives, curated by António Choupina. The exhibitions are open to the public until August 24.
