Osmose Dijon
A new generation of public service workplaces takes shape
Public buildings can be functional.
They can also be inviting, bright, and inspiring places to work and meet. The Osmose project in Dijon embraces this idea fully. Designed by Architecture Studio and developed by Groupe Lazard, the new territorial campus will bring together 400 agents of the Département de la Côte d’Or in two organically shaped buildings arranged around a central garden. The architectural language is soft, flowing, and open, with warm materials and a focus on wellbeing.
We at Rubner are proud to contribute to this project with a fully off site approach that places precision, sustainability, and technical excellence at the heart of construction.
Our scope: complete prefabricated timber façades
For Osmose, we manufacture all timber frame façade elements in our Île de France workshop. Each façade element is delivered as a complete unit, including windows, insulation layers, airtightness systems, and Douglas fir cladding. Curved wall elements form one of the architectural highlights of the project, and our workshop production ensures they are delivered with the exact geometry required by the design.
By assembling the façades directly on site, we guarantee a highly controlled building envelope with excellent thermal performance, superior airtightness, and a consistently high level of finish. This approach also reduces installation time, noise levels, and site waste, while providing high predictability for all project partners.
A project shaped by comfort, sustainability, and precision
The two buildings of the Osmose campus represent more than 7,600 square metres of new workspace. The interior volumes open generously onto balconies, planted loggias, and a central garden designed as a cool, shaded oasis. The slightly curved façades reinforce the organic character of the architecture, bringing softness and fluidity to the urban environment.
The buildings combine a concrete post beam slab system with a high performance timber façade envelope. This hybrid structure offers exceptional thermal comfort, thanks to the inertia of concrete working together with the insulation and airtightness provided by our timber elements.
The project places strong emphasis on sustainability. Biosourced materials, 700 square metres of photovoltaic panels, and a comprehensive rainwater management strategy all contribute to a responsible and resilient building. Osmose aims for a BREEAM Very Good certification, confirming its environmental ambition.
Timber construction, entirely off site
Our involvement in Osmose reflects our expertise in high precision prefabrication.
We deliver:
- approximately 3,800 square metres of complete timber frame façades
- 1,750 square metres of Douglas fir cladding
- curved elements manufactured with millimetre accuracy
- façade units fully equipped in the workshop before delivery
By producing these elements off site, we ensure that quality is embedded from the very first step. Every component is assembled in a controlled environment, protected from weather and humidity. This method guarantees a level of precision that is difficult to achieve on site and enables fast, clean, and efficient installation.
A campus designed for people
Osmose is more than a construction project. It is a new way of imagining public service workplaces. Bright office floors open onto generous outdoor spaces. The central garden creates a natural buffer that cools the surroundings. The organic forms of the buildings offer a sense of fluidity and calm, giving users a space that supports comfort and collaboration.
We are honoured to contribute our expertise to a project where sustainability, architectural ambition, and human wellbeing come together.
Delivery of the campus is planned for 2026, with occupation scheduled for 2027.
Our conclusion
Osmose is a strong example of what off site timber construction can achieve. It demonstrates how prefabrication, architectural creativity, and environmental responsibility can combine to create efficient, comfortable, and future oriented workplaces.
We believe that timber façades play a central role in this transformation, and we are proud to support the Dijon region in shaping the public buildings of tomorrow.
