Designed in 1936 by Georges Hennequin for Marcel Bloch-Dassault, this aeronautical factory in Déols combines red brick and glass half-roofs in a unique industrial modernism that bears witness to a pivotal period in French aviation.

History
At the heart of the industrial zone of the aéroport de Châteauroux-Déols, in the Indre, stand the remains of an exceptional industrial past: the former usine Marcel Bloch, the cradle of an aeronautical adventure that would shape France's destiny in the skies. Built hastily between 1936 and 1937 in a context of national rearmament, this factory immediately strikes one with the coherence of its modernist industrial architecture, conceived by the architect Georges Hennequin with functional rigour coupled with genuine formal ambition. The site is distinguished by the striking complementarity of its two great assembly workshops. One, austere and massive, presents itself with blind walls clad in red brick that evoke the robustness of northern industrial architecture. The other, more surprising, unfolds four glazed half-rotundas that flood the interior space with generous light, lending this production building an almost unexpected lightness. Together, they bear witness to a mature architectural vision addressing the demands of the nascent aeronautical industry. Beyond the workshops, the ensemble forms a veritable self-contained industrial microcosm: power station, heating plant, garage, canteen, water tower — so many satellite buildings that reveal the logic of a factory town conceived to operate autonomously during the years of urgency preceding the Second World War. This overall coherence is rare and constitutes, in itself, a lesson in industrial and social history. Bombed in March 1944, these buildings were reconstructed to their original design, thereby preserving the architectural integrity envisioned by Hennequin. Listed as a Monument Historique in 1991 and 1992, the site continues today to house industrial and tertiary activities, weaving a living link between a glorious past and a functional present. For the attentive visitor, each brick façade and each glazed rotunda is an open chapter in the history of French aviation.
Architecture
The Marcel Bloch factory in Déols is a remarkable example of French functionalist industrial architecture from the inter-war period, designed by the architect Georges Hennequin. The architectural approach is based on a clear duality between two main workshops, each expressing a different response to the constraints of aeronautical production. The first workshop is distinguished by its long blind walls of red brick, a traditional material from the north of France reinterpreted in a modernist industrial context, giving the building a massive, almost defensive presence. The second workshop is the centrepiece of the site: its four glazed half-roofs, set against the main volume, provide abundant zenithal light, essential for the meticulous work of the workers on the airframes. This discreetly elegant architectural solution testifies to the mastery of metal structures characteristic of the architect-engineers of the period. The metal framework forms the structural skeleton of these two large workshops, freeing up vast, uncluttered interior spaces with no intermediate posts likely to impede the flow of aircraft being assembled. Around these two central buildings are a series of ancillary buildings - the power station, heating plant, garage, refectory and water tower - whose sober architecture echoes the brick and steel vocabulary of the main workshops, ensuring the visual coherence of the whole complex. The identical reconstruction after the 1944 bombings preserved all of the formal language intended by Hennequin, making the Déols site one of the rare surviving examples of industrial aeronautical architecture from the inter-war period in France.
