We present here the indoor greening of the Renault Technocentre in Guyancourt, a large-scale project located at the heart of an iconic tertiary site.
This project was chosen for its technical richness, immersive design and sustainable commitments. It illustrates our ability to respond to complex issues in a very large-scale context.
The technique: The major technical challenge was to install plants of very large size – between 4 and 6 meters high – in two vast interior gardens of 40 m2 each, integrated into the heart of the building. Their implementation required precise logistics, adapted to access and structural constraints.
Each garden hosted a hundred plants, located on a drainage complex and an adapted substrate. In parallel, about 200 pots and plants were installed on the entire site, bringing nature into each living space. The whole project was completed in a short two-week period, a real challenge for the field teams, especially since the site, due to its size and attendance, required rigorous and coordinated organization.
The design: The entire project has been designed to offer a coherent and sensitive plant immersion, echoing the principles of biophilia. The two interior gardens have been designed as true living gardens, capable of transforming the experience of users in their professional daily lives. Designed to interact with natural light, the vegetal palette was chosen for its ability to evoke natural atmospheres, playing on the diversity of textures, ports and foliages. The plants become a full-fledged player in the living environment, capable of bringing well-being and connection with nature, breaking away from mineralization and the rigor of architectural volumes.
Sustainability: From the design phase, the project owner expressed a strong desire to integrate the project into a CSR logic. Emphasis was placed on the enhancement of existing resources: many bins, pots and plants were already present on site, some in place for more than 20 years. A precise inventory was carried out to evaluate their potential for reuse. Following this diagnosis, nearly 70% of the containers were preserved, restored and integrated into the new project, as well as 30% of the healthiest plants. This reasoned reuse approach has reduced waste, supply costs and carbon impact. In addition, the intervention was carried out in the immediate vicinity of the site (less than 20 km), thus reinforcing a local approach, economical and respectful of life cycles.
Designed by the Bureau d’ Études de Gally in close collaboration with the project management, and carried out by the work teams of the Jardins de Gally, this project benefited from complete support, from the diagnostic phase to the implementation on site. It is today always maintained by our teams, ensuring the sustainability of the development approach and the adaptation of plants to the conditions of the place.
