Osty and Associates

What Osty and Associates does

Osty et Associés (Atelier Jacqueline Osty et Associés) is a French landscape architecture and urban planning firm founded in 1983 by Jacqueline Osty, headquartered in Paris with a secondary office in Nantes. The firm designs parks, public spaces, urban districts, zoos, waterfronts, and ecological corridors for municipal and metropolitan governments across more than 40 French cities, with additional international work in Oman, China, and Benin. Its practice is organized around four integrated design principles: a multi-scale geographic approach tying each site to its neighborhood, city, and broader landscape; ecological design that integrates living systems, water management, and biodiversity into urban projects; scenographic landscape composition emphasizing staged visual sequences; and urban public space design centered on collective life. The firm competes almost exclusively for French and international public-sector commissions through design competitions and public tenders, frequently partnering with architectural firms (François Grether, Bernard Tschumi, Encore Heureux, Ellipse), engineering consultancies (INGEROP, Magéo-Morel), and metropolitan development agencies (SAMOA, SORELI). Osty and Associates operates as a private partnership with no disclosed external investment, subsidiaries, or M&A activity, monetizing entirely through project-based professional services fees determined by public procurement processes.
