ILE SEGUIN-RIVES DE SEINE, A MAJOR DEVELOPMENT OPERATION IN THE HEART OF GRAND PARIS

Île Seguin-Rives de Seine is a 74-hectare development project programmed for the old Renault plots in Boulogne-Billancourt, ideally located in the heart of Grand Paris and Culture Valley. On this magnificent site, whose industrial past has marked the collective memory of generations, a new district is about to be born. Ile Seguin-Rives de Seine thus gives a new lease of life to a plot unique in the Île-de-France. This exceptional situation has inspired an ambitious rehabilitation programme that will meet the key urban needs of the 21st century.

THE RENAULT PLOTS, AN INDUSTRIAL HISTORY WRITTEN INTO THE LAND

Founded in 1898, the Renault plots contributed to the development of Boulogne-Billancourt for nearly a century. The growth of the automotive industry was reflected in the rapid expansion of the industrial site: 0.5 ha in 1900, 36.5 ha in 1919. In the 1920s, space requirements increased further: the first building in Ile Seguin was erected in 1929. In 1939, the plants stretched for 100 ha from Meudon to Boulogne-Billancourt. After the war, the Société anonyme (limited liability company) known as Les Usines Renault, nationalised by Général de Gaulle, became La Régie nationale des usines Renault, which met with tremendous success with the 4 CV and the R4. After the 1980s, the Billancourt site was no longer adapted to the new manufacturing processes or the challenges of competition, mainly Japanese. This expansion was to lead to the stoppage of industrial production on 31 March 1992.

FUTURE-ORIENTED CHOICES FOR A KEY SITE

When Renault announced the stoppage of its production at Boulogne-Billancourt, an operation of national interest was planned, with the aim of factoring in the geography, environment and ‘soft’ modes of transport. A mixed syndicate was therefore formed. It covers the communes of Boulogne-Billancourt and Meudon, in the areas home to the Renault plots, as well as Issy-les-Moulineaux, Vanves, Saint-Cloud and Sèvres. The Conseil général des Hauts-de-Seine and the Région Île-de-France also committed to the project.

In 1997, the mixed syndicate, together with Renault, launched a town planning tender programme to sketch the outlines of the development plan. In 2000, the perimeter of the study was extended to include the Pont de Sèvres district, in order to ensure that the project was consistent with the neighbouring district.
In 2003, Boulogne-Billancourt city council created the ZAC (joint development zone), whose 74-hectare perimeter includes the Pont de Sèvres district and interchange, and whose blueprint specifying the public amenity programme was approved in April 2004. The Société anonyme d’économie mixte (SAEM) Val de Seine Aménagement, created in 2003, was tasked with undertaking the operation.

BOULOGNE-BILLANCOURT, THE SITE OF THREE WELL ADVANCED SECTORS

Ile Seguin-Rives de Seine is located in "District 3" of Boulogne-Billancourt, the second largest city in Île-de-France after Paris and hinge pin of the economic hub southwest of the capital. The operation is divided into three development sectors with different aims:
the Trapèze (37.5 hectares), a mixed sector (residential units, public amenities, offices, shops, green areas, etc.) to be developed in two phases; the west, already completed, and the east, well advanced and programmed for completion in 2016.

More information about the Trapèze

- Ile Seguin (11.5 ha): devised as a future international innovation hub dedicated to culture and the creative economy; open to the public since 2010, it now hosts installations in a prefiguration of its cultural future.

- the Pont de Sèvres district (15 + 10 ha): built in the 1970s, fast undergoing urban renewal to contribute to its decompartmentalization and enrichment. An agreement was signed with ANRU in July 2008. The living environment has already been transformed by new high-quality public spaces.

KEY FACTS AND FIGURES

The Île Seguin-Rives de Seine programme covers 850,000 m2, divided 

  • 382,300 m2 housing units and residences,
  • 281,300 m2 offices,
  • 186,600 m2 public amenities, activities and shops.

The urban and landscape design plan for the Trapèze details around twelve urban units called ‘macro-plots’, which form the king pin of the Île Seguin-Rives de Seine development project. Each macro-plot is assigned a joint development programme defined by SAEM and Boulogne-Billancourt city council, in partnership with DBS property developers (Hines, Icade, Nexity, Vinci). Following a competition, a ‘co-ordinating architect’ sketches out the composition and landscape of the macro-plot. He determines the ‘urban directives’ applied by the ‘operation’s architects’ tasked with designing each of the buildings.
