The project to extend line 11 of the Paris metro gives rise to the opportunity for a comprehensive redesign of the site owned by the Department of Water and Sanitation (DEA) between the two shopping centres of Rosny 2 and Domus. The construction of the metro line and maintenance and storage facility requires shifting all the DEA installations to the adjacent government-owned site.

Our architectural design proposes a project offering users a functional, landscape context conceived around open courtyards surrounded by a raised circulation formed by a green walkway. This route provides links between buildings, services and people and strongly contributes to converting these characteristically hard and stony spaces into a green heart for the city block.
Protected from the noise of the city, the internal courtyards form green perforations that establish a porosity between the core of the block and Avenue Général de Gaulle.
In this way, the treatment of buildings and the landscaping form an urban frontage interspersed with green perforations that reveal the internal façades of the project, without infringing upon the privacy required for the activities within.
Structured around the functional connections of the programme, the project presents an industrial and commercial identity that is clearly manifested by an understated architecture that advances its environmental credentials with high-quality, long-lasting materials.

In response to the expectations of the commission, our project plays an active role in the development of the new commercial zone with the creation of a high-quality urban frontage where the light-filled, environmentally-friendly architecture displays the technical and commercial activities in an elegant manner.

General operation:
The organisation of the working spaces respects a simple and functional division with regard to the two DEA offices and departmental depot, built around their shared layout.
The processing and operations activities are consistently grouped on two levels: single-storey workshops and storage areas in the yards and tertiary areas; rest areas and washrooms directly above the workshops.

The quality of the working spaces (industrial and commercial) is designed with a view to the environmental management of air quality (dual flow and air conditioning), soundproofing (orientation, double-wall, double-glazing), luminosity (natural lighting for work and living spaces), visual quality (green surroundings and quality of materials), and social qualities (spaces for encounter and exchange, green walkway).

Together, these proposals offer a functional working tool as part of a quality everyday lived experience that emphasizes human relations with particular attention paid to flow management and the quality of both work and relaxation spaces.
