Description

    Project Overview

     

  • The development transforms a former wasteland into an eco-district.
  • It is strategically located near the ring road of the Paris-Saint Nazaire axis, surrounded by industries and business parks. The area prevents urban sprawl.
  •  

    Housing and Community

     

  • The project provides 40% affordable housing and 25% social housing.
  • These housing options are well-connected to daily amenities such as schools, shops, and healthcare facilities.
  •  

    Urban and Natural Balance

     

  • The area balances its rustic nature with urban development.
  • The neighborhoods are designed to adapt to future expansion, ensuring long-term growth and flexibility.
  • It is part of the Nantes Green Star, a network of landscapes and gardens.
  • Ancient paths, vegetated streets, and a system of green and public spaces promote biodiversity and create a green structure.
  •  

    Transportation and Connectivity

     

  • The neighborhoods are connected by traffic axes, green paths, squares, and green spaces.
  • The area is a walkable city, with restricted car access to the city center and the creation of daily walking paths.
  •  

    Environmental Sustainability

     

  • The project features intelligent water management using the area’s natural slope for surface water flow and rainwater management.
  • Existing vegetated areas are reinforced by planting hundreds of trees, creating a network of shaded, cool spaces.
  •  

    Development and Expansion Plans

     

  • The original plan for future urbanization beyond the town was abandoned to preserve the district as a pristine natural area.
