On October 5, at the Centre de Congrès Prouvé in Nancy, the Union Nationale des Aménageurs (National Union of Developers) held its 2022 development awards ceremony. The development consortium consisting of Eiffage Aménagement, Crédit Mutuel Aménagement Foncier and Demathieu Bard Immobilier was awarded a prize in the "sober land use" category for its conversion of the Quartier Lizé in Montigny-Lès-Metz, a 9-hectare former military district.
This distinction rewards urban reinvestment in favour of urban extension on an operation where the approach of reasoned densification was done in a spirit of balance combined with broader objectives such as re-use, preservation of biodiversity and the fight against climate change.
In its initial state as a barracks, the site had 30,514 m² of undeveloped surface area where :
- 123 existing trees could be preserved,
- 8 buildings with a total surface area of 11,089 m² were preserved and will be rehabilitated,
- a biotope and open space objective was set. Thus, 37,732 m² of eco-vegetated area (i.e. 42% of the overall area) and 30,705 m² of open space (i.e. 34%) are planned, in which 431 new trees will be planted.
A balance has been found between the necessary development objectives with 755 dwellings planned around a controlled density of 83 dwellings/ha and the objectives of preserving the resource. The LIZE district is fully in line with the recent ambitious law on Zero Net Artificialization (ZAN) promulgated on 22 August 2021.
