Spain confronts a widening housing crisis with mass protests and a landmark eviction case that became a national symbol. The cooperativist group Sostre Cívic promotes a right-to-use housing model where members have long-term residence rights while the property is owned by the cooperative, funded by public, cooperative and European sources. Projects like Ca l’Ordit in Barcelona illustrate a scalable alternative, though critics say public land and funding remain insufficient for rapid expansion without stronger political commitment.
