Ilias Papageorgiou has stepped away from SO-IL, after having been a partner at the New York–based firm for five years. During Papageorgiou’s tenure, SO-IL developed itself into an internationally recognized design firm, completing projects in Paris, Seoul, and Milan, working with Mini Living, Versace, the Guggenheim Museum, and other clients. SO-IL’s more recognizable projects include the Kukje Gallery, the Frieze Art Fair pavilion in Chicago, Pole Dance in New York, and the Jan Shrem and Maria Manetti Shrem Museum of Art in Davis, California. To add to this list of accomplishments, SO-IL published its “visual and textual manifesto,” entitled Solid Objective: Order, Edge, Aura, co-authored by Papageorgiou in 2017.

Jing Liu and Florian Idenburg, SO-IL cofounders, will be staying at the firm.

Papageorgiou, an Athens-born architect, is a graduate of Aristotle University in Thessaloniki, Greece, and Harvard University’s Graduate School of Design. Papageorgiou is an adjunct assistant professor at Columbia University’s School of Architecture and Planning, having previously taught at Tulane and University of Thessaly in Greece.

Papageorgiou is starting PILA, an Athens and New York–based architecture firm.
