Cities worldwide face increasing pressure to adapt to rapidly changing climatic, demographic, and economic conditions. While the overarching goal of enhancing liveability is widely shared, the unique characteristics of each urban context demand customised approaches tailored to specific local conditions, histories, and social dynamics. Barcelona, a Mediterranean metropolis with a rich cultural heritage and a consolidated urban fabric, exemplifies these complexities. The city currently faces two interconnected and critical challenges. First, it must redefine the elements that constitute the new urban quality—rethinking public spaces, environmental performance, social inclusion, and economic vitality. Second, Barcelona needs to adapt its existing built environment to align with these redefined urban quality objectives.
