Ambitions : To propose projects with high environmental ambitions that meet a real need for service. For example, the local authority will be keen to promote the use of eco-materials, passive and energy-producing buildings, optimal air quality and comfort of use, and buildings that are part of a quality environment: Effinature certification.

Measures implemented :

The project blends into the local landscape by developing a typical bocage ecosystem. The hedgerows are preserved and made denser, enabling the conservation of a large badger population and protected species. The environment is diversified by the reintroduction of a meadow, an orchard and a wetland to regulate rainwater. Soil sealing has been reduced, with more than 50% of the plot preserved as open ground, and permeable surfacing chosen for the parking lots and soft path. This approach has resulted in a significant and qualitative re-vegetation of this former wasteland: more than 700 trees and shrubs will be planted on the plot, over 90% of which are local species, and 1,000 m ² of flower meadow will be sown.The two wooden buildings are fully integrated into this biodiversity-friendly approach. The structure is a habitat for birds, chiropterans and insects, with numerous built-in nesting boxes. The building fully integrates living organisms into its thermal regulation: trees and climbing plants provide shade for the glass roofs and courtyards. In addition, the construction methods used greatly reduce chemical and noise pollution during the construction phase.
