Design & Build: turnkey office fit-outs 

Choosing to manage your project in Design & Build mode is the guarantee of a comprehensive turnkey offer, including everything from the decoration design to the successful completion of the work. This turnkey office fit-out approach covers every stage of the project: consultancy, programming, interior design concept, workspace, space-planning, costing, contracting with all subcontractors, administrative procedures, coordination and receipt of works.


For professional fit-out projects, the fully-integrated Design and Build process significantly optimises deadlines, making the premises available more quickly. The Design and Build solution also ensures a shorter disruption of working and operating conditions if the site remains occupied during the work. This project management method offers several advantages compared with traditional management approaches: a single point of contact and a single invoice, and a firm commitment to a price, a deadline and a design project.
