The Grand Paris, or how to make the capital more attractive!


The project Grand Paris should take about 20 years to complete. It aims to create a united cluster seven times bigger than the current city of Paris, with a population 3.5 times bigger. The challenge consists of transforming a region that has been up to now characterized by its star shape into a more homogeneous territory.

What is the current size of Paris?

Paris “intra-muros”, meaning the part of the city located inside the ancient walls (now disappeared) is a very compact area of 100 square kilometers and 2,2 millions habitants. Its image of a closed city has been reinforced by the ‘Great Boulevards” built along the paths of the ancient fortifications, the ring road and the new circular tramway.

A large-scale project

The Grand Paris will include the City of Paris, the Seine-Saint-Denis, Hauts-de-Seine and the Val-de-Marne suburbs and several other neighborhoods situated on the outskirts.

Together, they’ll create an area seven times bigger than the historical Paris. Once the metropolis expansion is completed, Paris will house 7,5 millions inhabitants, more than half of the population of the ‘Ile de France’ department, representing 25% of the country’s wealth. The project aims to confirm the status of Paris as a world economic power and an example for sustainable development. The successful bid of the city for the Olympic Games in 2024 and its desire to build the reputation of a European financial center after Brexit is one of the steps the city is taking to detach itself from the touristic image it has. Another objective of the project is to improve the quality of life in the suburbs, mainly by improving and introducing new housing and transportation solutions.

A new transport network

The Grand Paris Express, as an automated transit network, will be the new metro of the capital city region. The Grand Paris Express will consist of a circular ring around Paris (line 15) and lines connecting developing areas (lines 16, 17 and 18). The Grand Paris Express will also involve the extension of existing metro lines. These new lines will surround the capital and provide links with the 3 airports, the business district and research centers. It will serve more than 165,000 businesses.

The Grand Paris Express in numbers
  • 4 additional lines
  • 200 km of new railway lines
  • 68 new interconnected stations
  • 2 million passengers a day
  • a train every 2 to 3 minutes
  • a 100% automatic metro system
  • 90% of the lines will be built underground
  • It will only take 34 minutes – instead of 53! – to go from Roissy Charles-de-Gaulle Airport to La Défense
  • It will only take 15 minutes – instead of 1 hour and 6 minutes! – to go from Orly airport to Paris Saclay University campus
A positive conclusion for all investors:

The ongoing project of The Grand Paris will have a positive impact on urban planning, housing, businesses and environmental protection. It offers a unique opportunity for all stakeholders, including developers, transport operators, public and private investors, construction companies, architects, urban planners and the population of Greater Paris.
