The Rivage program, formerly known as Plein'R, is located on the banks of the Seine in the town of Puteaux. The aim of the project is to design a contemporary, flexible commercial building that can accommodate both individual offices and open-plan, landscaped office spaces.

This real estate complex is spread over nine levels with four orientations. The new building will be built on the site of the former Olympe building.

The three levels of underground parking will be retained, providing 146 car spaces (including 30 electric), 85 motorcycle spaces, and 166 m² of bicycle parking.

The building offers a surface area of approximately 9,760 m² with a shop on Rue Jean Jaurès and a shared, adaptable hall offering a lobby and bar/cafeteria area. The building is attached to the adjoining buildings on the Seine side, while creating a series of tree-lined terraces on the Rue Jean Jaurès side and offering a view of Paris from the terrace on the top floor.

All outdoor spaces and terraces are landscaped.

The outdoor garden covers more than 1,100 m² of green space, and the series of terraces covers an area of more than 500 m².

The project is designed with a mixed wood-concrete structure (floors, columns, beams). The structural elements will be partially exposed in the interior spaces and will also be visible from the outside through a large glass façade. This innovative design allows the building to be constructed using low-carbon manufacturing processes.

All of the facades are composed of a largely glazed envelope with a regular pattern of windows. The 1.35-meter and 2.70-meter facade patterns adapt to the layout and design of the interior spaces, ensuring real comfort for the building's users.

The project highlights its environmental and energy ambitions with several certification and label objectives:

• HQE Sustainable Building Certification, Excellent level
• BREEAM NC 2016 Certification, Very Good level
• Wiredscore Label, Gold level
• Osmoz Label, Building lever
• E+C- Label, E2C1 level
