Atelier Ad Hoc is a Bucharest-based architecture practice focused on the relation between public space, informality and living conditions manifested in different situations around the city. Founded by Maria Daria Oancea (*1987) and George Marinescu (*1989) as a dual practice consisting of a design studio and an NGO, Atelier Ad Hoc engages with situations associated with social and spatial vulnerability. They develop support structures and spatial prototypes that extend resources available to communities, testing alternative visions for an inclusive city.
