Leonard Mackall House, 1686 Thirty-Fourth Street, Northwest, Washington, District of Columbia, DC

Significance: The Leonard Mackall House derives its primary significance as a prominently sited Second Empire-style house incorporating a smaller characteristic tension in Georgetown houses between the main north facade with front door and the rear south facade with the views of Georgetown harbor. The house is also an unusually dramatic demonstration of the extremes owners will go to make an older house much larger and of the current architectural fashion. Historical significance is derived from its prominent owners, such as the Mackalls who were an important late eighteenth- and nineteenth-century Georgetown family that owned several important properties, including Mackall Square (HABS DC-164), and the important twentieth-century theatrical producer Roger Stevens. A previous owner, Birne T. West, was also a prominent Georgetown resident, known for her garden, and civic activities, including historic preservation, in Georgetown. An obituary credited her with being a leader in getting legislation passed to save the Old Stone House on M Street.
