Committed to customers
Bouygues Bâtiment Grand Ouest is positioned as a full-service player involved in every stage of the construction value chain, from design to operation of buildings and structures. Thanks to our expertise, our clients benefit from solutions that enable them to successfully finance and manage their projects.

That drives our projects
We have more than 1200 employees who offer our clients a comprehensive range of expertise in design, construction and renovation in the fields of housing, functional structures, multi-product operations, industry and the environment.

Focused on the environmental transition
We recognise that our legacy as builders gives us a responsibility to future generations. That's why we strive every day to find ways to design, build and renovate differently, using low-carbon, biosourced or geosourced materials, reusing materials and promoting biodiversity. Our goal is to reduce our GHG emissions by 30% by 2030.

Driving change in the construction industry
Off-site construction involves processes based on factory manufacturing and on-site assembly, resulting in faster completion times, tighter cost control and a far smaller environmental footprint.

At the heart of our organisation
Bouygues Bâtiment Grand Ouest is committed to ensuring that everyone can thrive professionally by building career paths that reflect our core values: teamwork, simplicity, trust and a pioneering spirit. We prioritise safety for all, and uphold the highest standards of ethics and human rights.
