As envisaged in the June 1960 master plan, the Lorraine residence was designed on the principle of the Palais-Royal. The layout is entirely enclosed around a central garden, with the living areas of the apartments facing onto it. Built on stilts, the building consists of a mezzanine and three floors with raw concrete facades on the outside and glazed sandstone on the inside. The design is reminiscent of the La Tourette convent, designed by Le Corbusier. The Lorraine residence offers more than 110 apartments.

Winner of the Second Grand Prix de Rome in 1933, Robert Camelot (1903-1992) worked in Paris until 1977. In collaboration with Jacques and Paul Herbé, he worked on the pavilion for the Manufacture nationale de Sèvres at the 1937 Paris Exposition, among other projects. After the war, he designed urban plans for cities such as Reims, Nanterre, and Lisieux. From the 1950s onwards, he participated in the design of La Défense alongside Jean de Mailly and Bernard Zehrfuss. He is also considered the “father” of the first generation of towers and the residences known as the “Palais Royal.”
