Architectural visualizations for the competition proposal for the restructuring and extension of the historic Hôtel-Dieu hospital on the Île de la Cité, Paris, developed for Architecturestudio as part of the SPIE Batignolles team. Selected as one of three finalist teams in the AP-HP competitive dialogue, the proposal addressed the transformation of approximately 28,000 m² within one of Paris’ major 19th-century heritage landmarks, combining restoration, extension and contemporary healthcare requirements while preserving the architectural identity of the historic complex and opening it more strongly to the city.
