The “Pra Roman” site development by the Codha cooperative and the “Sur le Pra” association won the Binding Prize for Biodiversity 2023 because the development takes on the ecological and social networking functions for the neighbourhood and the city in an extremely exemplary manner and the project was approached in a participatory manner from the very beginning. The 2023 prize was announced as part of the annual theme “groundbreaking site developments”.

Ecologically networked living spaces
The “Pra Roman” housing estate with twelve apartment buildings on an area of 22,000 square metres is located on the outskirts of Lausanne. The surrounding area was integrated into the planning and construction of the 2020 development in an exemplary manner. For example, the award-winner created alternating humid wildlife corridors with integrated small structures for amphibians and small mammals and to promote wild plants. This awareness of taking responsibility for ecological connectivity in a larger system is central to the promotion of biodiversity in the settlement area.

Involving residents in planning
Raising residents’ awareness of biodiversity promotion was an important part of the “Pra Roman” project from the very beginning. Codha, the developer and cooperative for non-profit housing, initiated the association “Sur le Pra” at the beginning of the planning phase and developed a participatory process. Future residents met early on for site tours or nature observations and, with a high degree of design freedom, designed their near-natural outdoor spaces in workshops, which they later realised independently. The building owner supported them financially.

Vegetable garden enables encounter and sensitisation
One of these green spaces is the community vegetable garden. Here people exchange ideas and get to know nature as a basis for life. The culture of sustainable living and land use runs like a thread through the entire “Pra Roman” project. The surrounding ecosystems are observed, imitated in their diversity and connected with the settlement area.

“We are convinced that this excellent example will encourage other real estate developers to think about biodiversity at an early stage and involve many people,” says Peter Lehmann, vice president of the jury for the award.

Recognition prize goes to the Areal Bach project in St. Gallen
In addition to the main prize, the Foundation also awards a recognition prize of 25,000 Swiss francs for smaller sites. The Areal Bach, an interim use near the St.Fiden railway station in St.Gallen, receives this prize because it impressively demonstrates the potential of the many fallow areas in the cities. With its perseverance and commitment, the Areal Bach association overcame resistance, seized the opportunity and, together with the population, ecologically upgraded the areas and revitalised them with creative ideas. It has managed to get many stakeholders on board to realise a jointly supported, multifaceted project. A temporary green oasis was created from a non-place, which can lay the foundations for biodiversity and quality of stay for the planning of a future area development.
