Le Corbusier's drawing on page 144 of his Oeuvre complète indicates that he had used the "golden number" while designing the villa at Garches. Documents at the Fondation Le Corbusier show that this drawing was made at least 18 months after the original design. Moreover, the regulating lines here do not agree with those on an earlier drawing. The same sort of discrepancy is also found when comparing drawings of other early works. To explain the apparent contradictions and to understand Le Corbusier's method, his writings must be consulted. From these it becomes clear that the regulating lines were not used to design buildings but rather to modify or confirm the original plans. Hence more than one set of lines would fit a given structure. The plans for Garches must be understood in this light. When Le Corbusier took up the "golden number" he simply used it, after the fact, to further confirm his work at Garches. It is this later confirmation that we see in the Oeuvre complète.
