The Les Forges site in Grandvillars, with its power canal and buildings in stone and cast iron, bears witness to the town's two-century-old industrial history. Its restructuring is an opportunity to enhance this major economic space. The redevelopment project is based on several basic principles: preservation of the historic buildings, providing security for the various flows, and the desire, through the treatment of the exterior spaces as well as the buildings, to contribute to opening the site and keeping it active in the town of Grandvillars while creating quality relations with its neighbours.

For the LISI buildings, the project called for the historic building to be redeveloped into offices, as well as restructuring the process part in a compact and cohesive ensemble to the south of the building. The historic building thus becomes the figurehead of the project. This redevelopment is done using an extension that is entirely glassed in located on the northern end and which serves as the new main entrance to the office building. It is a true extension of the building, and its glass architecture, through contrast, will enhance the existing stone-and-overlay structure.

For the SELECTARC part, the process building is a light-coloured monolith of sufficient size to house all the industrial activities in a rational plan (dimensions 66 m wide by 120 m long). The height of its façades, 10 m, masks the technical roof penetrations and serves as acroterium for the technical roof surfaces. The façades are clad with a light-coloured vertical double metal skin with a foundation of light-coloured concrete. The composition pattern of the glass openings animates the façades in an abstract geometry. The small one-storey office building abuts the process building, and its volume is extended into an awning on the technical façade of the process building.
