In a context characterized by transformed or entirely replaced industrial buildings, the project preserves and extends by one floor the existing HEAD-Geneva building, built by architect Jean Erb in 1948 and classified as a 20th century heritage site.

The additional floor of 800m2 contains workshops, classrooms and offices. It adopts a simple, orthogonal and free plan, whose specificity lies in the alteration of the existing structural rhythm. In doing so, the new floor plan frees itself from corridors and offers a generous and continuous living space, and consequently, flexibility in the interior design. 

The extension is organized under a large metal frame that gives rhythm to the interiors. The project is defined by a perimeter, a simple limit that draws generic and efficient spaces. The rationality of the project is questioned by precise moments, where controlled irregularities are found.
