New design of Notre-Dame de Paris surroundings unveiled for the first time

Paris City Hall, in collaboration with Autodesk, announces the winner of a design competition to reimagine the area around Notre-Dame Cathedral

In 2021, while the restoration of Notre-Dame de Paris was underway, the City of Paris launched an international design competition to rethink the urban environment surrounding the iconic cathedral. Four multidisciplinary teams from around the world—comprising architects, urban planners, and landscape designers—were invited to submit their vision for the space. The project encompassed the cathedral’s courtyard, underground areas, and the riverbanks along the Seine.

Today, Paris City Hall revealed that the team led by Bureau Bas Smets had been selected as the winner of the competition by an expert jury. The announcement was made by Mayor Anne Hidalgo and Emmanuel Grégoire, the first deputy mayor of Paris.

Digital tools are driving the future of heritage preservation in France

Autodesk, the official technology partner of the competition, played a key role in supporting the City of Paris. The company provided advanced Building Information Modeling (BIM) solutions to create a detailed 3D model of the area around Notre-Dame, helping participants understand the site’s constraints and possibilities.

Throughout the competition, Autodesk worked closely with all four teams to help them produce realistic visualizations of their proposals. Digital models and documents were also shared on the Autodesk Construction Cloud, enabling real-time collaboration between the teams, the city, and Autodesk.

The use of 3D visualization allowed the jury to better understand the designs and make an informed decision. Once completed, all designs will be publicly accessible, offering Parisians a glimpse into the future of this historic district.

“The 3D visualizations of the competing projects, powered by Autodesk technologies, gave the jury a deeper insight into the proposed transformations of this historic area,” said Emmanuel Grégoire. “We hope that millions of visitors will enjoy this renewed space once the work is done.”

Charlotte Fagart, a landscape architect from Bureau Bas Smets, added: “Our project reimagines the public spaces around Notre-Dame as a series of climatic environments. Working with the Autodesk team helped us refine our initial concepts and ensured the jury could fully grasp the project through immersive experiences.”

Nicolas Mangon, VP of AEC Industry Strategy at Autodesk, said: “Paris continues to lead in digital transformation, positioning itself as a ‘city of the future’ by integrating advanced technologies into its urban planning. This competition demonstrated how intelligent 3D modeling and collaborative tools can accelerate decision-making and enhance public engagement with cultural heritage.”
