[5] In 1920 the house was purchased by Wright's sister, Jane Porter, and her husband, Andrew, who converted the two-story home into a duplex in the 1930s, with each floor separated into apartments.Two subsequent owners altered the home further: the kitchens and bathrooms were modernized, the front loggia enclosed, and a black iron gate was added to the entryway.[6] The work was overseen by restoration architect John Thorpe in collaboration with Doug Freerksen and his staff at Von Dreele-Freerksen Construction Company.The home is entered through a grade level front door into a deeply colored low ceilinged entry hall.Major spaces are raised above the surrounding grounds, and climbing the stairs to the upper level thrusts one into areas featuring soaring ceilings with trim echoing roof forms.
