BELLE-TERRE
// PHASE 1
1 PROJECT, 4 VISIONS
In Thônex, in the Geneva countryside, the first phase of the Belle-Terre district has been designed and built by four architectural practices, working together under a single impetus.
The Belle-Terre district, planned to be completed in three phases by 2035, recently saw the delivery and commissioning of its first phase. Designed and implemented by a team of architects and developers, this first phase, comprising two urban spaces, functions as a coherent entity.
"TAKING THE RISK, THE TIME AND THE COMMITMENT OF AN EXPERIMENTAL COLLEGIAL APPROACH IN THE SERVICE OF A MAJOR OVERALL AMBITION HAS ENABLED US TO GO FURTHER IN OUR THINKING AND ITS MATERIALIZATION!

ATELIER BONNET SALÈVE AND MONT-BLANC BUILDINGS
“We looked for a diversity of perceptions: in the hollowed-out area, questions about inverting courtyard or urbanity devices between exterior and interior… This put us in quite a strong creative mood.”
Pierre Bonnet, atelier Bonnet
(interview by Mélissa Henry)
To define the image of this new district, Pierre Bonnet turned to two models of minerality: the English layout of Bath and the majesty of the Geneva harbor. These references gave rise to a unique atmosphere, dominated by light colors and a high degree of architectural coherence.

ARAVIS AND MÔLE BUILDINGS
“Managing the long time of discussion
allows us to introduce self-criticism, and
to see that the notion of urbanity is in
perpetual evolution.”
Andrea Bassi, BCMA architects
(interview by Mélissa Henry)
Based on the guiding principles of horizontality, minerality
and chromatic homogeneity, the project establishes a common language. While the district has a strong visual unity, as if drawn from a single line, each building retains its own identity to encourage residents to make it their own.
JACCAUD + ASSOCIÉS
IMMEUBLE VOIRONS
“This project was a real lesson in trust and sharing. Relationships were strong and beautiful, both with the other architects and with the clients. When you’re able to work in a calm, trusting way, you’re able to do some pretty important things. (…) It was a lesson for us, and I hope it’s something that will continue to develop.“
Jean-Paul Jaccaud, Jaccaud+associés
(interview by Mélissa Henry)
This shared imagination, rooted in the texture and chromatic nuance of concrete, found expression in prefabrication. Prefabrication created a synergy between the project manager and the contractor, united around a craftsmanlike, technical approach to construction.

JURA BUILDING
“The great challenge of this project was the typological resolution of this complex urban form: a building with several angles and many variations to settle (…) It’s something that, in the end, gave a lot of pleasure, since it’s a work of deep reflection and analysis. (…) And it was to understand and embrace the sense of complexity of this form, since it generates views over the landscape, and a particular urban insertion of the building.“
Alain Robbe, Lin.Robbe.Seiler
(interview by Mélissa Henry)
The uniformity of the district is ensured by a unique construction method: facades made of concrete sandwich panels, prefabricated exclusively by the Geneva-based company Prelco. Planned a year in advance, this centralized order guarantees the homogeneity of the materials right from the start. This approach anchors the site’s identity in local materials and know-how.
