Metal 57

The conversion and expansion of a historic industrial building located on the banks of the Seine in Boulogne-Billancourt, a municipality southwest of Paris.
The complex, which has become the headquarters of BNP Paribas Reale Estate, was originally designed by Claude Vasconi in the mid-eighties as a Renault workshop and then partially converted in 2004, by design of Jakob + MacFarlane, through the creation of spaces for events.
The last project establishes a dialogue between the original architecture and the new expansion, but it is also related to the city through the creation of spaces open to the use of citizenship and in general of external visitors. These include a new square and, inside the building, a dining area, an auditorium, a conference space and a fitness area.
For the main area of Métal 57, which deliberately maintained its industrial aesthetic on the outside, Simeon has created 3,340 façade units, for a total area of 17,800 m2. In particular, alternating units in single and double skin were installed on the perimeter façades, with external moulding in aluminium, while on the façades of the two internal patios single skin cells were mounted, with reflective aluminium sheets that mark the frontispiece.
