ATTA is an international architectural practice based in Paris, founded by Tsuyoshi Tane in 2017. We are a collective of architects, designers, and creative professionals united by a shared vision of architecture that responds to memory, place, and the future. Our practice operates across a wide range of scales and typologies, with a portfolio that spans public and private projects in Europe, including France, Italy, Switzerland, and Estonia to Japan and other parts of Asia, as well as Brazil and the USA. Engaging deeply with multicultural contexts, we explore themes of archaeology, anthropology, and collective memory to construct architecture that are locally resonant and forward-thinking. Our team—comprising individuals from diverse cultural, academic, and geographic backgrounds—represents a truly multicultural generation, enriching our approach through lived global experiences.

In an era marked by rapid transformation, environmental crisis, and shifting identities, ATTA is committed to a long-term horizon in architecture. We approach each project as an act of excavation—uncovering the deeper narratives embedded in place. Rooted in our philosophy, "Archaeology of the Future," our practice seeks to create architecture that is grounded in memory and projects a vision forward—architecture that have never been seen, experienced, or imagined before.

Our major works include the internationally acclaimed Estonian National Museum (34,000m2), the Hirosaki Museum of Contemporary Art (3,500m2), The Al Thani Collection - Hotel de la Marine (760m2), Tane Garden House at Vitra Campus (700m2), and the Furoshiki Pavilion at the Hotel de Ville de Paris (500m2), as well as artistic installation "LIGHT is TIME" at Milan Design Week in 2014.
Currently, we are commissioned to design the 2.6 km long urban farm project - 388 FARM in Shibuya City, and the Imperial Hotel Tokyo, be completed in 2036.

ATTA’s work has been widely recognized, receiving numerous honors such as the Grand Prix of French Architects for Export (AFEX) in both 2016 and 2021, the Grand Prize of the Estonian Cultural Endowment, the 67th Japanese Award for New Face in the Arts by Japan’s Ministry of Education and Fine Arts, the Silver Medal of the Jean-Dejean Prize from the French Academy of Architecture, and the NAJAP 07–08 from the French Ministry of Culture and Communication.

Since 2018, our exhibition "Archaeology of the Future"—showcasing ATTA’s philosophy and recent works—has been presented in Japan, Brazil, Switzerland, Czech Republic and France.
