The rehabilitation of the Norac group headquarters in Rennes, made by Maurer & Gilbert Architects, has led to an elevation of a historic building with the creation of two new levels. To do this, an immense bioclimatic glass window in the form of a vault has been built, which has required the use of 3D computer programs and circumvents numerous regulatory limitations.
