Rewilding is the act of returning a built environment to its natural ecological state. MataAlta’s mission is to bring back green living spaces to densely populated urban areas. Our work is characterized by a strong environmental and social sensitivity. The spaces we design integrate biophilia, landscaping, architecture, urban planning, and engineering, with solutions guided by nature. Led by Sergio Carratalá, MataAlta is a Barcelona-based design studio established in 2017.
