The Camille Bloch production building site at Courtelary is now entering its final phase. The architectural concept of this industrial structure is based primarily on solutions which have been strongly marked by spatial and constructive rationality, while at the same time meeting high morphological, architectural and logistical requirements. Expansion of the production building has notably provided an opportunity to reconsider the chocolate factory's façade, improve the efficiency of internal processes and develop additional storage capacities.
