One of Spruce Street's grandest 19th-century mansions, this c. 1865 brownstone beauty on an extra-wide lot showcases the rich architectural details and scale that are hallmarks of the era. Designed by Samuel Sloan with a 1970 addition by Louis Kahn, it was the residence of Martin Meyerson, former president of the University of Pennsylvania (1970 ? 1981). The home's floor plan and architectural details are intact, awaiting a restoration to make it shine once again. Double doors open into a vestibule; inside, a world of grandeur opens up, with 15-foot ceilings trimmed in substantial crown moldings and tray and coffered millwork or elaborate "wedding cake" plaster design. Each level has four main rooms with tall windows and fireplaces in each, most with marble surrounds. The first floor features hardwood floors with substantial baseboard moldings. The central hall with the main staircase is large enough to double as a reception room. Attached to the original house is Kahn's 1970 contemporary addition with a sunroom and double kitchen designed for catering large parties ? there is plenty of space to create a twenty-first century kitchen and additional living space on the existing footprint. Notable is this property's garden space which includes offstreet parking for three cars. Personal quarters begin on the second floor, with four formal bedrooms, two en suite and all very spacious with extra-high ceilings sporting cove crown moldings, wood floors, fireplaces and tall windows. A hall bath serves the other two bedrooms. A service wing with laundry, bedroom and bathroom is on a "half level" over the rear of the house and separate from the bedrooms. The third floor provides four bedrooms, one en suite and all with fireplaces and comfortable proportions; a hall bath completes this level. With so much detail intact and room sizes that rival any in the city's grandest 19th-century properties, this is an opportunity to create a magazine-worthy residence along one of Philadelphia's most consistent and picturesque streetscapes.
