Sprawled across approximately 12,000 square feet and six levels, including the lower level, this classic neo-Federal 25'-wide mansion features seven bedrooms, five full bathrooms and two powder rooms. Located steps from Fifth Avenue and Central Park, this classic home epitomizes Upper East Side elegance and presents a rare opportunity to own a piece of Manhattan history. Behind a refined Flemish-bond brick and limestone trim exterior lies a home flooded with natural light, high ceilings and stately, large rooms. Entering through the vestibule, the elegant foyer unfolds before you and leads you up to the stately parlor floor. Behind French doors, a stunning formal dining room sits flooded in natural light, thanks to huge windows. It is serviced by a butler's pantry outfitted with custom copper fixtures and ample storage. A discreet service staircase leads to the garden level chef's kitchen, replete with top of the line appliances, a breakfast nook and an adjacent pantry. On the parlor level, sitting across from the dining room, a north-facing, dignified formal living room spans 23 ft. wide, with ceiling heights up to 12 ft., and is graced by a working fireplace and a massive wall of windows. A grand sitting room sits nestled in the middle of the parlor floor – a perfect spot for entertaining before or after dinner. A resplendent, gilded powder room with a custom Rosa Levante pink marble vanity services this floor. Coffered ceilings throughout the second floor are but a few of the meticulous decorative choices made. The third floor offers a timeless wood-paneled library with a fireplace and full built-in bar with custom crystal cabinets and polished black and white marble counters. A spacious office with a fireplace affords maximum privacy and quiet. Tucked at the back of the third floor is a large guest bedroom with floor to ceiling french doors opening onto a Juliet balcony overlooking the garden, and an ensuite bathroom. Encompassing the entire fourth floor, the palatial primary suite boasts an impressive bedroom , two walk-in closets and a working fireplace. The ensuite bathroom must be seen to be believed: a huge soaking tub, a separate walk-in shower, dual vanities and a separate W/C ensure an utterly relaxing, spa-like experience. Amplifying this majestic suite is a south-facing sun-room that opens onto a 250 sq. ft. finished terrace. The fifth floor offers three additional bedrooms - two with ensuite bathrooms - and a media/play room. Included in the offerings of this incredible home are staff quarters with a full bathroom on the garden level, a full basement with a laundry room and ample storage, a separate entry for deliveries or service. Built by John H. Duncan, the architect behind the General Grant National Memorial on Riverside Drive and located in prime Gold Coast with immediate access to Manhattan's finest shops and restaurants, this is a rare opportunity for the buyer who appreciates the exceptional location, as well as the magnitude and scale of this late 19th century townhouse. This is a co-exclusive.
