As a counterpoint to the parallelepipeds that dominate the La Défense district, all the towers feature curved shapes that interact with the winding roads along which they are located. The aim? To give these buildings the desired sense of integration and urban scale !

Michel Andrault and Pierre Parat, born in 1926 and 1928 respectively, both trained at the École nationale supérieure des beaux-arts, graduating in 1955. Two years later, they founded ANPAR (Andrault & Parat). The three Kupka buildings reflect the agency's clear evolution. Tasked with developing the Valmy neighborhood, the two architects gave it a distinctive look.
