c. 1870–1878, Frank Furness and others
This street is a display case of Philadelphia's High Victorian architecture—and materials, too, ranging from brick and marble to sandstone and serpentinite. Except perhaps for the house of Charles Stille, the University of Pennsylvania's provost, at number 2201, the entire north side was evidently designed by Furness and Hewitt before 1874. Across the street, at its west end, is a splendid row of Venetian Gothic houses. Finally, the Morton P. Henry house at number 2200 has all the hallmarks of an early, brutally reductivist Furness design: a sharply defined groove up the front marks the internal spatial subdivision of corridor and rooms, anticipating architect Louis Kahn's dichotomy of served and servant space.
