The mission

✔️ Support the transformation of a former industrial wasteland into a mixed residential area integrated into its environment.

✔️ Create quality public spaces for users in a plot with high construction density.

✔️ Plant a neighborhood of homes and shops to create the Bussigny of tomorrow.

The brief

Côté Gare, as its name suggests, is directly connected to Bussigny station, near the outskirts of Lausanne. This project is the first urban piece to initiate the new urbanism of the southern part of the city, with the downgrading of industrial and craft areas into mixed areas.

Composed of 6 buildings, the district combines housing, offices, shops and services. The site, in direct proximity to the station, is part of a territorial desire for soft mobility, with an emphasis on rail, cyclist and pedestrian traffic.

A former industrial wasteland transformed into a residential area geared towards soft mobility

The concept of this district is to integrate nature areas on all floors. Green roofs, hanging plants, planted containers, green waterfalls… The idea, in the long term, is to allow vegetation to colonize the building wherever possible.

We have conceptualized different spaces, all open to the public and freely accessible. In the interior courtyards of the buildings, the hearts of blocks offer areas of grassland, indigenous trees with great development to provide shade and various urban amenities.

The square to the east, in connection with the station, continues with a wide pedestrian walkway that leads to the activity area. It is extended by a set of footbridges which connect all the buildings to each other.

The great challenge of this project is to design quality outdoor facilities in a plot with a reduced footprint. That's why, in collaboration with the architects, we decided to make the most of the height to create a suspended public promenade that crosses the neighborhood.

Use height to create quality exterior layouts in a small space

The density of the project encouraged us to think differently to offer quality planted spaces. Our bias is to exploit the height. To green the entire neighborhood by creating a public space that starts from the ground floor and extends through the different floors of the buildings. Exhibition area, dry fountain, light effects, seats and community spaces enliven this walk open to the public. Connecting a network of footbridges to play with views and create breaths.

Focus on: the garden on the roof of the activity plateau

Located on the roof of the car park, the activity platform represents the core of the landscaping, activities and uses of the project. Accessible to the public and with an unobstructed view, this planted garden offers relaxation areas, grassy areas, games for children, shared vegetable gardens and private terraces.

The plant palette on this upper part is made up of perennials, flowering shrubs, trees with small and medium growths. Despite a high load-bearing capacity (1000 kg/m2), we had to resort to distribution slabs, lightened earth and a strategic distribution of more massive trees on the pillars of the car park to meet the complex technical constraints of a park on slab .

A first experience in conquering the BIM process in the landscape

Started in 2015, Côté Gare is our first project carried out in BIM at the agency. At the time, the BIM process was little used in construction in French-speaking Switzerland, and even less in landscaping. Not content with having been precursors, this first experience above all enabled us to grasp the innovative aspect of this approach to architectural and landscape design. A dive into the digital model that gave us a taste for technological innovations!
“The greatest success of this project? Clearly to have produced our first BIM model on a project of this magnitude: a great introduction to the subject! “
