XTU is an award-winning architecture and design firm founded in 2000 by principal architects Anouk Legendre and Nicolas Desmazieres. Located in Paris, France, XTU specializes primarily in academic and environmental research in addition to residential and cultural buildings.

The portfolio of the firm displays several museum projects beginning with the Jeongkok Museum in South Korea followed by the Museum of Civilizations on Reunion Island and the Cite du Vin Museum in Bordeaux. The firm is also responsible for the French Pavilion at the Milan Expo in 2015. In these projects, XTU explores complex geometries with the integration of parametric design. A free and organic approach encourages the use of a wooden structure synchronized in 3D.
