This design was the direct practical outcome of the Town-Planning Stand at the Paris "Salon d'Automne" of 1922. It dates from a period when every kind of difficulty presented itself simultaneously. Though theories had been put forward and principles developed for clearing the ground in "L'Esprit Nouveau", everything in this house had, architecturally speaking, to be created anew : methods of construction, an efficient structural solution of the roof problem and of the window-surrounds, parapet, etc. The design reveals its free planning - the bathroom being placed in the centre of the floor area. It likewise defines the form of the window and its proportions, which are correctly adjusted to the human scale.
