Sotirios Kotoulas is the founder of Sotirios Corp, an architecture and design studio based in North America with projects around the world. He received his professional degree in architecture from The Cooper Union in New York City and completed his M.Arch at McGill University in Montreal, studying history and theory of architecture with Alberto Pérez-Gómez. His book Space Out, published by Springer-Verlag and edited by Lebbeus Woods, explores the spatial and material dimensions of invisible and immeasurable electromagnetic phenomena.

Recently, Sotirios completed Sherbrook Flats, a structural masonry mixed-use apartment building in downtown Winnipeg, Canada, which is currently being researched with engineer John Wells for its dynamic thermal resistance. A house for artist Katherine Bernhardt is under construction in Old San Juan, Puerto Rico. Recent projects include the design of the Kaari Upson exhibition and bookstore for the DESTE Foundation in Athens, Greece, and the renovation of an existing structure on an 84-acre property near Ojai, California, for Kyle DeWoody.

Sotirios has designed and built artist studios for Garth Weiser and Francesca DiMattio in upstate New York, and subsequently created the exhibition design for Garth Weiser: Paintings 2008–2017 at The Contemporary Austin in Texas. Additional work includes a house for Max Snow on the Snake River in Jackson Hole, Wyoming; an artist studio for Mickalene Thomas in New York City; and a pool pavilion and pool house in Connecticut.

Sotirios also collaborated with the late Elder and Knowledge Keeper Dr. Dave Courchene, Nii Gaani Aki Innini (Leading Earth Man) of the Anishinaabe Nation, on a new architectural space for ceremony, ritual, and education at an ancient sacred site in Manitoba.

More recently, Sotirios and artist Jamie Diamond collaborated on a conceptual Chase Manhattan Bank branch for Albuquerque, New Mexico. The project was on view from April to November 2024 at the Prada Foundation in Venice, Italy, and an exhibition catalogue is now available worldwide.

Working with his family’s construction and restoration firm, Alpha Masonry, Sotirios oversees and manages new masonry construction as well as major historic restoration projects for Parks Canada, the Judd Foundation, and the Sun Tower in downtown Vancouver for Allied REIT. The Sun Tower heritage conservation and seismic stabilization project recently received the Outstanding Achievement Award from the City of Vancouver. He is also currently involved in the restoration of the Manitoba Legislative Building. The exterior and interior masonry restoration of Donald Judd’s Architecture Office Building was recently completed for the Judd Foundation. The building was officially dedicated on September 19, 2025. The restoration was carried out with disciplined precision to maintain Judd’s original architectural intent.

Sotirios specializes in the full rehabilitation and preservation of modern architecture at multiple scales. He teaches an architectural design studio and seminar at Rensselaer Polytechnic Institute, and has previously taught at universities across Canada and the United States.

Sotirios served as a research consultant at the Cooper Union Institute for Sustainable Design in New York City for the Lessons from Modernism exhibition, which examined sustainable details and environmental strategies in early modern architecture. The exhibition traveled across the United States, and its accompanying book, Lessons from Modernism: Environmental Design Strategies in Architecture 1925–1970, is published by Monacelli Press.

Sotirios currently serves as the board chair of Anthology Film Archives in New York City and sits on the board of the International Peace Garden, located along the shared border between the United States and Canada. He has completed long-term leadership roles at several cultural institutions, including a ten-year term as board chair of Basilica Hudson in Hudson, NY, a full nine-year board term with the Winnipeg Symphony Orchestra, and a full nine-year term as board president of the Plug In Institute of Contemporary Art in Winnipeg, Canada.

Sotirios exhibited a new body of work titled Star Stories in the exhibition, Conceiving the Plan: Nuance and Intimacy in the Construction of Civic Space, at the 2021 Venice Biennale of Architecture, Italian Pavilion, curated by Yael Hameiri Sainsaux and Alessandro Melis. The exhibition is on tour, and the book is published by Skira and is available worldwide.
