De Pas, D’Urbino & Lomazzi is an architecture and design studio founded in Milan in 1966 by Jonathan De Pas (1932–1991), Donato D’Urbino (1935), and Paolo Lomazzi (1936). Active across architecture, product design, and theoretical experimentation, the group emerged within the radical research climate of the 1960s and 1970s. Their work challenges the boundaries between function, language, and behavior, using objects as critical and narrative tools. De Pas, D’Urbino, and Lomazzi conceived design as an open practice, capable of reflecting on social and cultural changes and anticipating new ways of inhabiting and interacting with space.
