This article analyses the comparison between several of Candilis-Josic-Woods’ representative projects between 1947 and 1955 and Le Corbusier’s Villas and Unité works. Through this analysis it establishes the interaction between their approaches while simultaneously defining and exemplifying their general and specific contribution to the understanding of the façade as a space and not as a surrounding. Analysis of the thickness of the façade and of its relation with the interior and exterior space is an important design criterion when contemplating a more urban architecture, and an architecture that is more liveable and more integrated with the environment. This is a quality that is ever more relevant and pertinent as an answer to the densification and horizontalization of cities.
