The project is located in Bussigny, at the heart of the urban and economic densification plan for the Lausanne-Morges metropolitan area. The triangular plot, bordering the A1 motorway, benefits from a strategic location on the outskirts of Lausanne. It is also well served by public transport and current and future active mobility options.
The Cocoon business park spans four buildings, offering a total of 38,000 m² of commercial space (offices, shops, restaurants) and 23,000 m² of storage. These high-energy-performance buildings feature flexible workspaces that open fully to the outdoors. The guiding principle for this landscaped project is to create a verdant haven.
Cocoon: an ambitious project combining flexibility, sustainability, and mobility
The architectural principle of this new business district: three fully glazed buildings protected by a fourth building situated along the highway. This "Screen" building serves both as the project's exterior showcase and as a guarantee of acoustic comfort for the site. Our mission? To create a green working environment that contributes to the well-being of its users.
The Cocoon project reflects a strong commitment to environmental preservation. Its landscaping also addresses climate challenges by providing sustainable solutions. A predominantly native plant palette offers a green setting to welcome local wildlife.
The exterior landscaping is designed as a meeting point between free-flowing peripheral vegetation and an organized central courtyard. This lush urban park is shaped in particular by the planting of 75 native trees of the first and second size, 200 shrubs on the roof of the screen building and 1,920 m2 of green roofs.

Imagine a green oasis to complement the life of the neighborhood
By following the topography of the land, we proposed a bespoke, elegant and comfortable green roof. The landscaped spaces are designed along two main axes: a structured inner courtyard around the central oval building – the nerve center of the district; and a peripheral edge composed of spontaneous and free-growing vegetation – the green setting around Cocoon.
A regular grid pattern animates the pathways, staircases, and ramps around the central square. Terraces, green roofs, and lush vegetation interact with the stone, softening its rigidity. Along the outer edge, meadow species offer abundant vegetation with a symphony of colors and varieties. Large trees planted directly in the ground punctuate the space and add height.

A sustainable and dynamic urban park on the outskirts of Lausanne
In a large-scale urban transformation project like this one, landscaping always raises complex questions. Our greatest achievement on this project? Creating a green oasis to complement the life of this new neighborhood. The Cocoon business center is scheduled for completion by the end of 2024. This business hub isn't the only urban development Arfolia is working on in Bussigny. We also participated in the Côté Gare residential neighborhood , which is also currently underway.
