Le Corbusier's piloti perform a number of functions around the house, both inside and out. On the two longer elevations they are flush with the face of the façade and imply heaviness and support, but on the shorter sides they are set back, giving a floating effect that emphasises the horizontal dimension of the house. The wide strip window of the first-floor terrace has two baby piloti to support and stiffen the wall above. Although these piloti are in a similar plane to the larger columns below, a false perspective when viewed from outside the house gives the impression that they are located deeper within the house than they actually are.
