Proposed Extension of the Executive Mansion, ca. 1891

This plan suggested a proposed expansion for the Executive Mansion attributed to First Lady Caroline Harrison around 1891. Compiled and drawn by architect Frederick Dale Owen, the plan proposes the addition of a private central court enclosed by historic and official wings as well as a series of greenhouses and conservatories housing palm gardens and a lily pond. While this proposal never came to be realized, the plan anticipates President Theodore Roosevelt's construction of the East and West Wings in 1902.
