Why did Le Corbusier design his buildings without suporting walls?

Le Corbusier designed his buildings without supporting walls to promote a more open and flexible interior space, allowing for a free flow of light and air. By utilizing a system of pilotis (columns) to elevate the structure, he freed the ground level for functional use and enhanced the overall aesthetic. This approach also facilitated a more modernist vision of architecture, emphasizing functionality and the integration of nature with built environments. Overall, it represented a shift towards innovative architectural practices in the 20th century.
