An 1880 brick rowhouse in Baltimore, a modern townhouse in Houston and a 1985 ranch house in Sarasota, Fla.

Maryland Institute College of Art is a half-mile east, and the Johns Hopkins University medical campus is two miles southeast. It is also near the Joseph Meyerhoff Symphony Hall, the Patricia & Arthur Modell Performing Arts Center at the Lyric and the University of Baltimore.
