mobile architectural office created in 2012, by Fabien Brissaud, has been recognized and awarded through several international competitions and has won many competitions in France. Our studio seeks to create a quality architecture, contemporary and timeless at the same time in direct link with our theoretical research on architecture, society and our preoccupation on the implementation of a particular constructive device. MAO develops each project "in situ", studying and drawing inspiration from the existing architecture to create a project that respects its environment. Our work is based on a contextual approach that is not satisfied with a stereotyped response. Each territory has its own history, geography, materiality and constraints. Our work is based on the concept of "critical reuse", which implies always starting from the existing state in order to design a contemporary project in adequacy with the environment. It is a question of introducing into the project process a material part such as history, cartography, heritage, economy, the human element and the insertion acquired over the years and another immaterial part such as the notions of scale, limit, mobility and place. In today's globalized and generic world, we strive to create architectures specific to each territory. The credo of the agency is not only to respond to a commission but, above all, to re-question the problematic for each project through a strategic discussion with the actors of the project and more widely of the territory.
