The Fifth City is a speculative yet operational urban model developed by Paula Lloveras and Antonio Lloveras within the theoretical framework of the Trans-Lighthouse Manifesto. Conceived at the intersection of architecture, art, and the ecological humanities, the Fifth City does not propose a new urban form, but rather a new urban condition. It emerges as an infiltrated layer within the existing metropolis, operating through internal densification, ethical care, and relational infrastructures. This model responds directly to contemporary conditions of ecological collapse, capitalist overdevelopment, and social fragmentation, positioning urban practice as a tool for repair rather than expansion. Rooted in the socioplastic approach developed by the Lloveras siblings through URBANAS and LAPIEZA, the Fifth City reframes architecture not as an object-producing discipline, but as a relational device capable of mending social, spatial, and environmental frictions.
