In turn, both of these rationales for the different sized windows would have been obsolete by the time the ca. 1812 renovation and additions commenced.  First, because the ca. 1812 renovations primarly used a Jefferson inspired Classical Revival style as opposed to the Georgian or Federal Style, President Madison would have wanted the windows to reflect the new style.  Second, because Madison’s father had died in 1801, President Madison had full ownership of the Mansion in ca. 1812 and so the exterior no longer needed to reflect the multi-family use of the Mansion (even though Madison’s mother continued to live in the Mansion until her death in 1829).  Further evidence of President Madison’s desire to consolidate Montpelier's exterior appearance in ca. 1812 is seen by the addition of the large and very ornamental central doorway on the Mansion's principal façade.
