Steel, in the service of contemporary architecture and energy performance, in this new tertiary project for the French school of osteopathy in Nantes (France).

The engineers and architects from Ryo and Atelier David had a lot of discussions about how to proceed with this extension. The JI Boreas XLS cassette was the obvious choice to enhance the steel structure.
