H3o architects is a Barcelona-based architecture firm formed by Adrià Orriols, Joan Gener and Miquel Ruiz. Their practice promotes innovative and speculative designs in the fields of architecture and urbanism facing the challenges of contemporary society. Climate change, social responsibility and the hybridization of human and non-human realities are at the core of each project. In the field of theory, the studio investigates the membrane as the epidermis of architecture and its social, political, and ecological implications. Among its projects are the conversion of the Convent of the Poor Clares into the new library in Arenys de Mar, the 155- unit housing block at Kop-Dakpark (Rotterdam), winner of the Europan 15 Rotterdam Award, the renaturalization of the square in Castell d'Aro, and the new residence for the elderly in Es Migjorn Gran, Menorca, all of them ongoing projects.
