This exhibition, sponsored by the city of Barcelona following its designation as World Capital of Architecture 2026, presents the outcomes of an international competition aimed at transforming the party walls of ten districts into innovative facades. It showcases the proposals from both emerging architects from around the globe and established designers. The project illustrates the evolution of these designs from initial concepts to concrete implementations, reflecting a collaborative effort to enhance urban aesthetics and engage the community in a dialogue about architectural identity and urban revitalization.
