After the redesigned windows were added to the virtually restored ca. 1797 house it became clear why Madison wanted to replace the windows during the ca. 1812 renovations and additions.  Not only were the ca. 1797 windows not symmetrically aligned with the ca. 1764 windows, but they were also not even close to the same size.  Why would Madison have installed glaringly narrower windows in 1797?  One theory is that the windows used in ca. 1764 were out of fashion by ca. 1797 and reflected a bulkier, Georgian style of window and President Madison therefore wanted his new windows to reflect the newer, lighter Federal style.  Another theory suggests that different sized windows may have been used to inform visitors approaching the Mansion that the interior was divided into two separate sections.  So the different sized windows could have been an intentional architectural detail used by the forty-six year old Madison to retain his individualism even as he shared a common roof with his parents.
