Châtenay-Malabry eco-neighborhood construction

Reintroducing nature into cities is part of developing new forms of agriculture. Eiffage’s status as a “sustainable city demonstrator” has been enhanced by this test-bed ecodistrict

A wide-scale operation

In Châtenay-Malabry on a 20-hectare plot formerly occupied by the Ecole Centrale, the LaVallée eco-district is currently being developed, covering approximately 223,000 m2 of floor space. The LaVallée eco-district is ideally situated opposite the Grenouillère future aquatics centre and between the parc de Sceaux and the Coulée Verte that connects the town to Montparnasse in Paris.

The programme will create 2,200 homes (16% of which as social housing), 36,500 m2 of office space to accommodate LIDL’s national head office, 15,000 m2 of retail space (approximately 30 new stores), a middle school for 700 pupils, a 19-class primary school, a 60-cot crèche for up to 90 children, an urban farm, 280 parking spaces and vast private and public green spaces spanning around 7 hectares.

The new eco-district aims to set a new standard, implementing innovative sustainable solutions, right from the phase to dismantle the Ecole Central, through to the design of the eco-district as well as the way it is managed and people live their lives there.


Urban development driving innovation in sustainable development

The LaVallée eco-district is the Group’s new demonstrator, but on a whole new scale – the previous demonstrator spanned 3.5 hectares, while LaVallée covers 20 hectares. It builds on the solutions developed for Smartseille by improving and adding to them, in particular by integrating the circular economy and urban nature.
Eiffage Aménagement, via SEMOP, endeavours to create an eco-district demonstrator for a sustainable city in the Greater Paris region that boasts four strategic characteristics:
  • Low-carbon design
  • Circular economy
  • Urban nature
  • New uses (especially digital)
