Bastide Niel development area

Transforming a brownfield site into a pleasant, sustainable neighbourhood

Located on the right bank of the River Garonne in south-western France, the Bastide Niel project is part of a vast programme to strengthen Bordeaux city centre by reclaiming brownfield sites.

On a 35-hectare site occupied by a former barracks and disused railway installations, the project aims to create a mixed, sustainable and pleasant neighbourhood. Artelia is actively contributing to this transformation.


The Bastide Niel concerted development zone (ZAC) project, which will be revised in 2020 to include higher environmental targets, is fully in line with a mixed-use eco-district approach that takes account of climate change issues and targets for reducing CO2 emissions. Covering an area of 35 hectares, the project includes 374,000 m² of construction, of which more than 250,000 m² will be residential. More than 4,000 new homes are to be created, including 1,000 for social housing, to accommodate up to 10,000 residents. A real place to live, the Bastide Niel ZAC also includes 63,000 m² dedicated to shops, a tertiary and hotel cluster and a range of local services. The district will be connected to the tramway.

The project stands out for its strong sustainable approach. It makes partial use of existing railway buildings and their renovation, and is made up of building blocks on a human scale to give priority to breathing space and quality of life. Particular attention has been paid to public spaces and their planting. Of the 16 hectares set aside for public spaces, more than 2 hectares will be given over to vegetation (1,800 trees and 3,000 shrubs). A micro-forest and vegetable gardens are also planned. In line with the Bordeaux frugal label, Bastide Niel has also set itself the objective of favouring short and virtuous circuits in the use of materials (re-use approach).

As an assistant to the project owner in terms of sustainable development, Artelia has been a driving force in terms of eco-design and has endeavoured to reconcile ecology, respect for the budgetary framework and exploitation of technical opportunities in order to propose viable and sustainable solutions. Our teams organised the phasing of work on the public spaces and blocks, and are currently supervising their completion.
