Marjetica Potrč (pronounced ; born 1953) is an artist and architect based in Ljubljana, Slovenia. Potrč's interdisciplinary practice includes on-site projects, research, architectural case studies, and series of drawings. Her work documents and interprets contemporary architectural practices (in particular, with regard to energy infrastructure and water use) and the ways people live together. Background and early career Potrč was born in Ljubljana, the capital of the Socialist Republic of Slovenia, which was then part of the Socialist Federal Republic of Yugoslavia. Her parents were both writers. Potrč's father, Ivan Potrč, was a well-known Slovene social realist novelist and playwright from the Styria region, and the main editor at the publishing house Mladinska Knjiga. Her mother, Branka Jurca, was a teacher and magazine editor and also a well-known author of children's literature, who was born in the Karst region of western Slovenia but moved to Maribor, where she met Marjetica's father. Marjetica Potrč received degrees in architecture (1978) and sculpture (1986, 1988) from the University of Ljubljana. In 1990, she moved to the United States. Her installations from this period often involved walls of various kinds; for example, Two Faces of Utopia (1993, made for the Slovene Pavilion at the Venice Biennial), and the series Theatrum Mundi: Territories (1993–1996). A statement she made at the time—"I don't make objects. I build walls"—positions her work against object-based sculpture. In 1994, she moved back to Ljubljana. Since then, Potrč's work has developed at the intersection of visual art, architecture, and social science. Participatory design and sustainable solutions In 2003, Potrč was invited to spend six months in Caracas, Venezuela, as part of the Caracas Case Project, and carry out research on the informal city. There, in collaboration with the Israeli architect Liyat Esakov and the residents of the La Vega barrio, she developed the project Dry Toilet: an ecologically safe, waterless toilet was installed in the upper part of the La Vega barrio, a district in Caracas that has no access to the municipal water grid. Dry Toilet is one of a series of community-focused on-site projects by Potrč that are characterized by participatory design and a concern with sustainability issues, particularly in relation to energy and water infrastructures. Other important projects are Balcony with Wind Turbine (Liverpool, 2004), Power from Nature (Barefoot College, Rajasthan, India, and the Catherine Ferguson Academy, Detroit, Mich., USA, 2005), and A Farm in Murcia: Rainwater Harvesting (Murcia,
