Renzo Piano Building Workshop Redesigns Montparnasse Commercial Centre as a Pedestrian District
During a presentation to the press held at Paris City Hall on January 7, 2026, architect and Pritzker Prize laureate Renzo Piano released the first images of the transformation of Montparnasse's emblematic shopping center and CIT Tower into a pedestrian-focused district in Paris, France. The project, commissioned to Renzo Piano Building Workshop (RPBW) in 2022 by the co-owners of the commercial complex, proposes both a visual and functional transformation of the 1970s low-rise retail development into a more traversable space characterized by transparency and openness. The design was developed in parallel with the redevelopment of the Montparnasse Tower, led by Nouvelle AOM, to reshape the broader tertiary complex into a contemporary Parisian block oriented toward public life, environmental performance, and everyday use. The project reopens the site to the city, reconnecting streets and restoring continuity between Montparnasse and its surrounding neighborhoods through new public spaces.
