The brief

The project is located in Bussigny, at the heart of the urban and economic densification plan for the Lausanne-Morges conurbation. The triangular plot, along the A1 motorway, benefits from a strategic location on the outskirts of Lausanne. It is also well served by public transport and soft mobility, current and future.

The Cocoon business center is spread over 4 buildings for a total surface area of ​​38,000 m2 of commercial space (offices, shops, restaurants) and 23,000 m2 of storage space. High Energy Performance buildings accommodate modular workspaces, fully open to the outside. The watchword for this landscaping project: create a cocoon of greenery.

Cocoon: an ambitious project mixing flexibility, sustainability, and mobility

The architectural principle of this new business district: three fully glazed buildings protected by a fourth located along the highway. This “Screen” building is both an exterior showcase for the project and a guarantor of the site’s sound comfort. Our mission ? Create a green working environment that contributes to the well-being of users.

The Cocoon project is part of a strong desire to preserve the environment. Its landscaping also responds to climate issues by providing sustainable solutions. A predominantly native plant palette offers a green setting to welcome small local fauna.

The exterior developments are designed as a meeting between free peripheral vegetation and an organized heart of the island. This lush urban park is being shaped in particular by the planting of 75 local trees of 1st and 2nd size, 200 shrubs on the roof of the screen building and 1,920 m2 of green roofs.


Imagine an island of greenery to support neighborhood life

By marrying the topography of the land, we proposed a tailor-made plant covering, elegant and comfortable. The landscaped spaces are designed along two main axes: a heart of the block structured around the central oval building – the nerve center of the district; a peripheral edge composed of spontaneous and free vegetation - the green setting around Cocoon.

A regular pattern animates the paths, stairs and ramps around the central square. Terraces, green terraces and lush vegetation interact with the mineral to break its rigidity. On the outer edge, meadow species offer abundant vegetation with a symphony of colors and varieties. Large trees planted in the ground punctuate the space and provide height.


Responding to the climate challenges of today and tomorrow

Climatic challenges and user well-being were integrated into the landscape project from the very beginning of the design. The species chosen are resistant to a dry climate, significant sunshine and high temperatures to anticipate the environmental challenges of tomorrow. Planting numerous plants throughout the neighborhood creates shaded areas to reduce heat islands. The 3,000 m2 of green roofs and the wetland with water retention basin contribute to the diversity of the site's environments.


A sustainable and dynamic urban park at the gates of Lausanne

In a large-scale urban transformation project like this, landscaping always raises complex questions. Our biggest success on this project? Having created a green setting to support the life of this new neighborhood. Delivery of the Cocoon business center is scheduled for the end of 2024. This business center is not the only urban piece that Arfolia is working on in Bussigny. We also took part in the Côté Gare residential district , also currently under construction.
