The best Le Corbusier’s design of openings and protections 
In many other situations I have criticized the brutal ingenuity of the openings designed by Le Corbusier for almost all his buildings. His disregard of the role of filters and thus the uncontrolled light and heat entries made his beautiful homes in the twenties become popular and universal disastrous examples.
After his wife’s remarks (see study ) he began, in these Maisons Jaoul, to use shutters and other protections, to fragment the "pan de verre" to distribute the fragmented openings in strategic situations and to build a facade on a frame. For me the last one is the most interesting solution for an opening.
