In the AGF (General Assurances of France) headquarters designed by the architects Joseph Belmont and Pierre-Paul Heckly and delivered in 1980, the bold urban challenge was to recreate a new urban fabric while keeping the site open to its environment, in a constrained context.

The main objectives of the renovation project are
– to respect the form and spirit of the building: of the 9 original pre-stressed concrete modules, only one is partially demolished
– to improve the amount of natural light
– bringing the building up to construction, safety and accessibility standards
– the development of a qualitative and flexible office building, adapted to current lifestyles: creation of shops and a multi-destination conference centre
– the integration of greenery
From the central hall, art permeates the entire building, in the stairwells, the corridors and on the executive floors.
