Established together with Stéphanie Bru in 2007, BRUTHER works in the fields of architecture, research, education, urbanism and landscape. The practice develops national and international projects such as the Cultural & Sport Center Saint-Blaise, Paris, France (2014); Helsinki Central Library, Finland (2013); and the New Generation Research Center in Caen, France (2015). BRUTHER won the international competition for the Swiss Federal Institute of Technology (EFPL Lausanne) Life Sciences Center, UNIL Campus, which is under development with Baukunst (2016-24). BRUTHER stands for a specific architecture, adapted to the needs of each project in order to offer maximal living conditions. Adaptability and evolutivity of the building are fundamentals in the office practice.
