Trapèze Eco-district: modernity at the service of quality of life


The Trapèze eco-district covers part of the Billancourt-Rives de Seine neighbourhood, south of Boulogne-Billancourt. It is made up of two parts, Trapèze west and Trapèze east. The first is located next to the Billancourt-Rives de Seine district while the second follows Avenue Émile-Zola from the Seine before switching to Rue Yves-Kermen to the east, then returning to the river via Rue Nationale. Lying opposite Île Seguin, the Trapèze runs along the Seine and covers around 74 hectares. It is one of the largest labelled eco-districts in France.

Quartier Ecoquartier du Trapèze - Boulogne Billancourt


The Trapèze district owes its name to its shape, which evokes a trapeze. Historically, it was part of the grounds on which Renault factories extended at the beginning of the 20th century, which became more and more successful and needed more space. The factories were destroyed in the early 2000s, and the work on the Trapèze eco-neighbourhood, completed in 2018, was a major redevelopment site for former brownfield sites.

Cultural sites

  • Maison Saint-François-de-Sales: This 21st century oratory has a modern architecture. Its timber formwork and large bay windows give it a contemporary style in keeping with the spirit of the Trapèze eco-district. Its patio and multi-purpose central hall are not only used for worship, they also show the evolution of places of worship and their uses.


Local landmarks

  • Tour Horizons (Horizons tower): Located at the edge of the Trapèze eco-district, this original tower rises to 88 metres in height and features three distinctly styled “degrees”. The result of a competition between architects won by the Ateliers Jean Nouvel, it can be seen from afar and features hanging gardens.
  • Ardeko building: Located on Avenue Émile-Zola, this building is one of the first buildings delivered during the creation of the Trapèze eco-neighbourhood it symbolises today. A huge office building, it pays homage, by name as much as by architecture, to the Art Deco style that characterised the constructions of Boulogne-Billancourt during the 1930s.



  • Parc de Billancourt: although it contributes to the recovery of the district’s rainwater which is then used for watering, the Parc de Billancourt is above all the green lung of the Trapèze eco-district thanks to its 7 hectares of nature. Divided into several types of environments, it offers a variety of vegetation, from peat bogs to sandy areas and meadows. The park also contains a fitness trail and walkways.
  • Parc Unik: Not far from the Seine, this small park allows the practice of several sports activities such as football or fitness thanks to facilities provided for this purpose.
