PAU won the invited global competition to design an expansion of I.M. Pei’s original building, completed in 1995. Competing against an exclusive list of invited architects, including several Pritzker laureates—PAU’s design was selected on the strength of its distinct palimpsest design approach that reimagined and extended Pei’s architecture. Instead of creating a wholly separate object, PAU’s design brings new life and dimension to Pei’s original pyramid as well as the larger site, with new internal and external public spaces intended to immerse visitors in the future of Rock & Roll. The expansion will roughly double the size of the museum, including a new entry lobby and public space; an acoustically-designed and sub-divisible performance, classroom, and 1,350 person event venue; reinvented permanent and temporary exhibition space; new food and beverage offerings; replacement office space; and a complete rethinking of circulation systems that extend into the landscape.
