Extraordinary historical details are on full display at this 5,300 square-foot corner residence with a walled garden and addition suitable as a home-occupancy professional office or additional living space. The main residence, with its 12-foot ceilings, extra-tall sash windows, fabulous antique hardware and eight fireplaces, is a beautifully preserved celebration of Philadelphia's Federal-era ascendency. A vestibule entry with fanlight windows leads to a hall-parlor floor plan with grand-scale formal living and dining rooms separated by floor-to-ceiling doors. Intricate plaster ceiling medallions, extensive crown molding and substantial fireplace mantles and surrounds are old-world, quality elements. Keep the formality or move toward a contemporary aesthetic both work in this home. Stairs take you down to a custom kitchen, wine cellar and family room/casual dining area with brick arches and fireplace. The roomy, galley-style kitchen is lined in a long run of timeless, natural wood cabinetry with an open, walk-in pantry, 6-burner gas cooktop with downdraft vent, Sub-Zero refrigerator/freezer, convection oven/microwave and two wall ovens. A dumbwaiter stands ready to send dinner to the formal dining room. On the second floor, where the high ceilings and millwork are carried through, the den feels like a reading room at a private club. A custom built-in hides a wet bar and television. Relax by the big fireplace; chat with friends; grab a book from the shelves flanking the fireplace; nap; enjoy the light from the three tall windows. On the third floor, the main bedroom suite accommodates a seating area and like much of the house, has very good storage. The big marble bath hints at an Art Deco feel and provides two console sinks, a soaking tub and stall shower, plus a walk-in closet. Two additional en suite bedrooms are located at the back of the house on the second and third floors. Accessible from inside the main house or from a separate outside entrance, the professional office, which includes a fireplace and powder room, can also be incorporated into the main house as additional living space. Modern mechanicals, including central air, are in place. Off-street parking is available nearby. A cherished home for its current owners, this residence is an exceptional opportunity in Washington Square West.
