As the hour of doom approaches for the curtain wall one will appreciate the value of a continued effort which has, since the very beginning, established in front of the glass wall of the dwelling, an effective "sunlight regulator" (from the spring equinox to the autumn equinox no ray of sunshine will touch the glass during the hot hours of the day). The loggia was created, from the beginning, in order to bring about the "inside-outside" contact between dwelling and nature.

The orientation was dictated: both east and west glass façades are provided with loggias. (Theoretical experiment before 1945 when M. Raoul Dautry, Minister, Director of the French National Railways, gave Le Corbusier the commission for a Unité d'Habitation, the latter accepted "on the conditions that he would be free of all reglementation". This permitted the Modulor to enter into largescale housing developments restoring truly human dimensions to the dwelling. In the course of travels through the various regions of indigenous building these had been rediscovered.)
