The Gambetta Tower and the Maréchal-Leclerc residence, together with the Les Dauphins residence, form a complex of 715 apartments. The Gambetta Tower alone has 304 apartments. The Gambetta Tower also mirrors Défense 2000, located at the other end of the EPAD perimeter.

For the building, the architects sought a variety of volumes and heights based on the principle of decomposing the plans.

The Maréchal-Leclerc residence is terraced. The fluting of its prefabricated panels creates a play of light and shadow on the rounded facades while guiding rainwater.

Partners since 1946, Daniel Badani and Pierre Roux-Dorlut established their main agency in the Paris region in 1952, after numerous projects in the south of France and Africa. In addition to housing projects, the most prolific duo of the Trente Glorieuses (the thirty glorious years of economic growth in France after World War II) designed several school, administrative, and public complexes. They made history on the monumental axis leading from the Louvre to La Défense by developing the underground space of the Tuileries. They then designed the Maréchal-Leclerc Gambetta complex.
