The only project by the little-known architect Maurice Plançon, the La Défense residence has an unusual status: it is intended to rehouse people who have been expropriated from the La Défense area. It has 264 apartments spread over nine floors.

The result of the creation of the Exprodef real estate company by these expropriated residents, with the support of the EPAD, the residence's layout echoes the Palais-Royal style established in the original master plan for the business district's housing. Like all first-generation buildings, the ground floor is raised on stilts, ensuring the permeability of the complex. Built like a block of stone, the building nevertheless features an interior garden.

Maurice Plançon was a French architect born in 1923 and died in 2012. He worked for over 50 years as an architect and urban planner, designing projects in a variety of fields: housing, schools, green spaces, and urban renewal projects.

He was known for his sensitivity to local and regional contexts. Developing a pragmatic approach to architecture, he always sought to design buildings that met the needs of users while being economically viable and functional.

Among Plançon's best-known projects are the renovation of Place Stanislas in Nancy, the construction of the Jean Weille sports complex in Nancy, and the design of the Les Epinettes residential neighborhood in Reims.
