Description

Ideally situated on a picturesque, tree-lined block between Madison and Park Avenues. Built in 1877 by architect J.H. Valentine as one of ten Neo-Greek residences, this 20 ft wide brownstone spans five levels and is 6,550 SF, combining historic architectural character with gracious proportions. Ceiling heights range from 10-12 ft, and an elevator serves all five levels. This splendid residence is awash in sunlight throughout the day and offers an ideal template for an elegant lifestyle. Its handsome façade features a third-floor bay with grand-scale transom windows crowned by leaded-glass panels. Oversized windows across the north, south, and east exposures fill the interiors with abundant light. Additional features include three-zone central heating and air conditioning, an elevator, three wood-burning fireplaces, a sophisticated alarm system and an intercom. Four-inch-wide oak floors run throughout the residence. The landscaped garden and fifth-floor terrace offer 560 SF of outdoor space, both equipped with irrigation. First Floor: From the recessed front garden entrance, an iron front door sets the tone for this exquisite residence. The Garden Level includes a large Entrance Gallery with a French limestone floor and a magnificent eat-in Kitchen. The Kitchen is supported by a cozy Den, ideal as an office. The Den provides access to a rear staircase leading to the Butler’s Pantry and wet bar above. This floor is completed by a coat closet and a Powder Room. Both the Kitchen and the Den open to the charming trellised Garden. The secluded garden retreat is landscaped with ivy, mature plantings, decorative brick columns, and an attractive fountain. Parlor Floor: This level features a grandly-scaled north-facing Living Room with a wood-burning fireplace and large windows framing leafy tree top views. The Dining Room is defined by a beautiful rounded alcove. The Dining Room is supported by a Service Pantry and Wet Bar and a staircase leading to the Kitchen below. Throughout this level, shining mahogany doors, gorgeous plaster crown moldings, and exquisite period detail enhance the elegance of these boldly-scaled rooms, along with architectural details such as a round window overlooking the Living Room from the dramatic staircase. A second Powder Room is conveniently accessible. Third Floor: The Third Floor is currently configured as a grand, spacious Primary Suite, but it can be reconfigured into two large, private Bedroom suites. At the front of the house, a bay-windowed Library or Bedroom with a wood-burning fireplace, custom closets, and built-in bookshelves. Its adjoining bathroom includes a windowed shower. The spacious rear Bedroom incorporates a bay-windowed sitting area, southern light throughout the day. This room is supported by a travertine-clad spa Bathroom appointed with double vanities, a separate bathtub, and a dedicated shower room, with south- and east-facing windows providing abundant natural light. Fourth Floor: The rear Bedroom is accompanied by a spacious, windowed spa bathroom with a whirlpool bathtub and separate stall shower. An additional windowed dressing room offers excellent storage and may provide flexibility to create a second bathroom. The front bedroom is distinguished by a wood-burning fireplace and a coved ceiling, supported by an ample Dressing Room. Fifth Floor: Above, the Fifth Floor - two additional Bedrooms, both with their own ensuite Baths: the first enjoys north-facing tree-top views, and the second features a large central skylight and double doors opening onto a trellised terrace measuring 12 x 22 ft. Surrounded by mature greenery, the terrace offers a private and inviting outdoor retreat. Cellar: A well-appointed basement provides laundry facilities and extensive storage.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.

How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
