Heavy restructuring of a historic heritage Building on Henri Barbusse street in downtown Marseille

The former Post Office building, located at 19 Henri Barbusse Street in Marseille’s first district, was built in 1938 by architect Auguste Marie Joseph Bluysen, who is also known for his work on the Grand Rex in Paris. This structure was designed to be an annex to the Central Colbert Post Office, which had become overcrowded. This one-of-a-kind structure, designated as a Historic Monument, is fully entwined with the Saint Cannat Church, producing a dramatic contrast between two structures that are completely different in nature.

Arkadea, which was formed by the merger of Icade and Poste Immo, wanted to requalify this G+5 building by generating office activities as well as a coworking space on the ground floor. The overall goal of this project is to remodel the structure in a retro-modern manner that is respectful to Mr. Bluysen’s vision in order to restore its original appearance, which sadly experienced disastrous modifications in the 1990s.

Our tasks and roles
accomplished in this project

Axiolis performed a full structural diagnosis on this project in order to determine the overall construction system of the structure. We also conducted five stress tests, which justified the load-bearing capacity of the flooring at 400 kg/m2, with the goal of facilitating a change in usage and avoiding considerable reinforcements that were originally contemplated in the design. Load testing on floors imitates the project's operational overloads on-site in accordance with serviceability limit states. Water-filled reservoirs are used to load the floor to be tested. Electronic sensors measure the structure's deformations when the reservoirs are filled and emptied.

Axiolis also created the implementation plans, which included the construction of extra levels, an extension of the basement, the opening up of load-bearing walls, and the installation of a rooftop restaurant with an accessible terrace.
