This pair of three-story, bay-fronted Italianate houses was designed by Schoenborn, a draftsman on the Capitol extensions under Thomas U. Walter during the 1850s and 1860s. He claimed credit as the designer of the Capitol dome's structural system. The attenuated and well-balanced proportions, restrained use of fine quality cast-iron ornament, and attention to subsidiary decorative details distinguish these two houses from less expensive builder-erected examples in the same mode.
