The Manhattan Tower is the result of a commissioning process led by Henry Bernard. It was he who advised Cogédim on the construction of two towers that would become one under the expertise of Michel Herbet and Michel Proux. The building expresses the original twin design, but the two volumes are connected by curved walls that contrast with the dominant orthogonality of the towers in the neighborhood.

The perfectly smooth glass facades change color with the changing light, giving the tower a certain originality.

Known as one of the main architects of the Beaugrenelle district in Paris's 15th arrondissement, Michel Proux is no stranger to slab urbanism. He worked with Michel Holley on the Olympiades project in the capital's 13th arrondissement.

In 1974, in the midst of the Beaugrenelle project, which he took over after the death of Raymond Lopez in 1966, he joined forces with Demonès and Srot to launch Défense 2000. Far from stopping there, he collaborated, at the suggestion of Henry Bernard, with Michel Herbert on an original project for La Défense: the Manhattan Tower.
