RARE OPPORTUNITY to acquire a spectacular and exceptionally large 20-foot-wide neo-Georgian townhouse with over 11,000 interior square feet on one of Manhattan’s best tree-lined townhouse blocks. The Adele Kneeland Mansion is located on the south side of 71st Street between Lexington and Third Avenues. It is a six-story plus full basement residence with soaring ceiling heights, magnificent marble fireplaces, and original architectural details throughout. It has an elevator servicing all floors, two entrances, a stunning double-height solarium, and a large 1,250 square foot landscaped rooftop terrace with excellent city views. A dramatic open stair-way that connects all above-grade floors greets you upon entry, and large windows on four sides provide abundant natural light throughout. This house is well suited for a live/work situation, a medical practice, school, private art museum, non-profit organization, or magnificent private residence. Constructed in 1874 as one of seven row houses, the house was purchased in 1915 by a wealthy heiress named Adele Kneeland who hired the architect John B. Snook to substantially renovate and enlarge the property. Snook replaced the original brownstone front with an elegant red brick and limestone facade. He raised the floor levels, added a four-story extension to the rear, added a fifth and sixth-floor extension to the top, and reconfigured the interior layout. After Ms. Kneeland’s death in 1937 her heirs converted the house into apartments, but preserved most of the original room configurations and architectural detail. In 1982 the first two floors were made into doctor’s offices for the renowned ophthalmologist Dr. Stephen Kelly, who retained the architect Jay Spectre and interior designer Geoffrey Bradfield to convert the top three floors into an exquisite Art Deco triplex with a double-height glass conservatory and exotic Macassar Ebony-paneledd-paneled library. Today the townhouse still benefits from these substantial upgrades made over time, many of which would no longer be permitted today. The house will be delivered vacant. Sale proceeds will benefit a charity for medical scholarship. Showings begin week of 3/7/22. Current Configuration: BASEMENT: Exam Rooms, Offices, Storage, Mechanical Room, Half Bath, 8-foot ceilings. ENTRY FLOOR: Entry, Office Reception, Exam Rooms, Half Bath, Garden, 9-foot ceilings.
