x3m : arhitektura + urbanizam is a Croatian Zagreb-based architecture studio established in 2003 by architects Mirela Bošnjak, Mirko Buvinic and Maja Furlan Zimmermann.

They graduated from the Faculty of Architecture of the University of Zagreb in the late 1990s, and have received various awards and recognitions both for works built and competition projects ever since. Their office is a small practice where the three partners are also the only employees. Nevertheless, they design and manage all their projects fully in-house. Almost all of their commissions and constructed works are the result of winning the first prize in an open design competition.
