SEURA Architects, France
David Mangin is a Practicing Architect and co-partner of SEURA Architects in Paris, France since 1996. He is a Professor of Architecture in the School of Architecture at the University of Marne-La-Valle and the ENPC (The National School of Bridges and Roadways). He has formerly undertaken the role of visiting Professor at various universities around the world including Venice, Singapore (NUS) and Versailles. He is a member of the Scientific Councils for various urban committees and has co-authored various learned publications and popular books on urban underground space. He was instrumental in producing the “Mangroves Urbaines”, a book outlining the urban connectivity and opportunities of the metro to their surrounding urban areas in Paris, Montreal and Singapore. He has a modern grasp of the complexity of our urban spaces and how they can benefit communities and provide spaces for enjoyment both aesthetically and functionally. He has been involved in many of the Architectural improvements of metro stations and the older metro underground spaces in Paris as well as Europe and Asia and will provide insight into the challenges of the past and the potential future direction of underground space in our ever increasingly complex urban landscapes.
Urban Underground Interconnectivity and Lessons Learnt from 40 years of Functional Metro Planning in Dense Urban Cities: urban mangroves, from metros to city
The Grand Paris Express (GPE) is an extension of the public transport network of the Ile de France to improve the living and travel condition of its inhabitants. This future network is composed of four automatic metro lines that will eventually form a double ring road around Paris, completing the current network and creating a more effective global network. Nearly 200 kilometers of metro will be created and should carry 2 million people from, to and around Paris. In addition, 68 stations are planned, of which 48 will offer connections with the existing RER, metro, tram, Transilien TGV, and Orly and Roissy-Charles-de-Gaulle airports.
This conference will present some basic principles with the objective of making the GPE effective, comfortable and articulated with the municipalities concerned and its future projects. It was developed in 2015 as part of a study for the Atelier International du Grand Paris and published in a book named “Mangroves urbaines, du métro à la ville. Paris, Montréal, Singapour” (David Mangin et Marion Girodo avec Seura architects, Editions Carré / La Découverte, 2016). In fact, we think that the GPE will have an impact on the evolution of uses and modes of travel in the metropolis and contribute to the reduction of CO2 emissions only if it responds to those summed up principles: stations allow efficient multimodality, drawdown routes are pleasant et the network is accompanied by changes in the territories at the height of the challenges of optimizing the new scale of Paris and Grand Paris, such as connections in between stations and other building forming what we call an “urban mangrove”. In fact, we propose a kind of illustrated work guide in six points which, when applied to the design, implementation and representation of stations and their neighborhoods, appear as principles for the design of such a future transport network, in Paris or other cities around the world. They are based on a 5 years research on the underground transportation networks and their relationship with the aerial city, especially on three cities: Paris, Montréal and Singapore. This is why those existing examples will also be presented as “lessons” for the underground works to be built.
