At La Fonderie, architecture is as much an object of study as a framework for work. It is an everyday material, lived by those who draw it, anticipate it, and at times pass judgment on it. Home to the City of Strasbourg's Directorate of Construction and Built Heritage — the client body responsible for every building project across the city — La Fonderie is designed by architects and for architects. It is a vast inhabited studio, a collective and collegial practice where design, research, delivery, management, and heritage protection converge. The project occupies a singular built environment: on the street side, a German building dating from 1892, altered in the twentieth century, and at the rear, an older half-timbered structure belonging to a seventeenth-century Alsatian tradition. Between the two, and above all, a residual courtyard in the form of a narrow lane — destined to become the heart of the project.
The restructuring undertakes a radical heritage restoration of the German façade, brought as close as possible to its original truth. The stonework is repaired and completed; the shopfronts, balconies, and ironwork are reinstated. Inside, the focus shifts toward a more subtle work on uses, atmospheres, and the legibility of workspaces. The interior street becomes the architectural lever of the project, and the nerve center of La Fonderie's life. It serves at once as entrance hall and reception space, a place of exchange and conviviality, of passage and of both vertical and horizontal circulation. Offices open onto it via galleries, and walkways span across it to connect the two buildings.
It develops a vocabulary of clarity, transparency, and lightness, and the variety of its luminous whites becomes the backdrop against which the city's built production is displayed. In contrast, Prouvé's red furniture pieces and oversized Tolomeo lamps accompany the scale of the space and offer a knowing nod to the architects it houses. Plants climb along cables up toward the skylight, intertwining with a cloud of suspended light fixtures. The architecture here is as rigorous as it is airy — a faithful image of a place devoted to concentration, but equally to creation and inspiration.
