 The first remodeling work on the Ellwood Mansion took place as the 19th century drew to a close. The changes, commissioned by Isaac Ellwood, were meant to reflect more popular architectural styles including the Georgian and Colonial Revival. Many of the building's original Gothic features were replaced with more Classical elements. On the home's exterior, some of these changes can be observed in the addition of the portico and porte-cochere. Inside the home, the dining room was enlarged with the addition of the semicircular bay on the mansion's north facade.
