The History

Maïra, Ludovic and Grégoire meet in 2002 on the campus of the California Polytechnic University. Their ways drawn by a lot of projects in common will construct quickly a road that will take them to the foundation of the agency MU during spring 2009.

From the beginning of his creation, the team MU insisted on the quality of the exchanges between the players of the project and the users.

In order to reply to the requirements of the project, and to encourage the explorations, MU took the opportunity of surrounding itself with numerous partners with a known expertise. A little bit more every day, it strengthens its partnerships project management team coherence, putting in synergy every skill and creating constant emulations.


After 6 years of existence, MU has already completed lot of projects as a “Fertile” House, a Bio Cooperative shop, two sport centers with their solar walls, a Children House which received a prize from the government for its innovation, a sport venue, a fire station,  and many others.

The office is currently working on several public institutions as a media library but also on several housing buildings as two wooden constructions or two large housing blocks with an experimental 70 apartments tower in Paris (with XTU office) selected by a jury of experts.


MU has been invited to many public competitions and took part to workshops as the “unsustainable architecture” conference, during the 10th architectural Biennale in Sao-Paulo.

The office received in 2012 from the French Cultural Ministry the prestigious price of “Les Albums des jeunes Architectes et paysagistes” (AJAP) which reward every two years the young emerging architecture and landscaper offices.
