AREP group's "Reinventing Paris 3" project exemplifis sustainable urban renewal, combining Haussmannian heritage preservation with flexible, future‑proof programming.
The Seafrigo headquarters are located in a rapidly changing area, on the interface between the port and the historic city of Le Havre, and express the new urban vitality of the Citadelle district. The building sits on an open site affording unimpeded views of the docks, the River Seine and the city. Extending the sea metaphor initiated by the ENSM (French Maritime Academy) building, the Seafrigo headquarters are moored alongside the Eure Basin. The east and west blocks of the building accommodate all the workstations in a total floor rea of around 700 sqm ensuring equal comfort for a 400-strong staff. The width and structural continuity of the floors alon with the footbridges linking them to one another on either side of the atrium on levels 1 and 2 provide a flexible distribution of the staff. Dynamic thermal simulations and calculations based on the RT 2012 regulations led to the following choices:
• Improved envelope performance due to the size and performance of glazing and the installation of motorised solar protection;
• heat and cold generated by a heat pump;
• photovoltaic panels on the roof. The building qualifis for Bepos / E3C1 certification.
AREP Group's mission:
From concept design through to tender documentation
