This house was designed by Philadelphia architect Adolph deRoy Mark, who was known in the 1970s for introducing a new modern look to a very old neighborhood. deRoy Mark
worked closely with Louis Sauer, the architect responsible for many of the houses around Society Hill. Sauer and deRoy Mark did New Market together, which was fun while it lasted. [See comment below.]
Designed in 1972, this deRoy Mark house features some of his classic inclinations, including a persistently unique use of brick and tile—dig the 18th-century cobblestone floor of the turret room (oh yeah, and there's a turret room) and the floor made from pieces of Independence Hall. Despite its singular features, this house has been on the market for a long time. The $12,000-plus in property taxes last year probably hasn't helped.
