“The Vegetalized Block” - Eco-Design of a Rainwater Depollution Station in Champigny-sur-Marne, France

Client : VAL DE MARNE County

Location : Champigny-sur-Marne (94), France

Project : Architectural and landscape design of the rainwater depollution station

Mission : Architecture HQE® and Landscaping


Area : Site of 8 100 m²

Cost : 42 300 000 €

Date : Competition 2022

The rainwater depollution plant will be located in the south of Champigny-sur-Marne and will sit at the interface between a preserved natural environment and a rapidly changing urban landscape.

The architectural and landscape design of the future rainwater depollution station meets the goal of integrating the buildings into its environment through architectural arrangements and high quality materials.

To reach this goal, the main axis of the project was to free the architecture – the ecological monolith – by integrating it into the natural landscape of Marne and reconstructing the biodiversity on the site in a “vegetalized block” therefore making a smooth transition between the center of Champigny and its large landscape.
