Description

Banish cookie-cutter aesthetics in this gorgeous six-bedroom, four-and-a-half-bathroom townhouse that blends original architectural details, high-end contemporary updates, and a rich palette of designer finishes. An expansive, flexible layout, peaceful private garden and mid-block Gramercy Park location make this a must-see single-family residence in one of Manhattan's most coveted neighborhoods. Inside this 4,068-square-foot showplace, tall ceilings decorated with restored original ceiling medallions and crown moldings soar above original hardwood floors. Curated wall and window coverings are coordinated with complementary paint colors, while beautifully updated bathrooms boast contemporary fittings and fixtures, including two with extra-deep, oversized soaking tubs. Six working fireplaces add warmth and beauty throughout. A classic high stoop and vestibule entry usher you to the parlor level, featuring beautiful herringbone flooring, a stately decorative fireplace and tall windows flanking a traditional pier mirror. Enjoy a generous footprint for formal seating and dining areas, while original pocket doors reveal a comfortable living room overlooking the rear garden. Head to the garden level to discover an impressive open gourmet Bulthaup kitchen and family room filled with rustic beamed ceilings, polished concrete floors, exposed brick, floating built-in cabinetry and a wall of sliding glass doors. Chefs will appreciate the rows of sleek cabinetry, center island/breakfast bar, and upscale appliances, including a vented gas cooktop, combination microwave/oven, refrigerator/freezer, and dishwasher. Enjoy casual gatherings in this old-meets-new space, or step out to the nearly 900-square-foot paved garden for al fresco dining and entertaining under a canopy of mature trees that provide shade and notable privacy. A powder room, private entrance, and a secondary suite perfect for guests complete this level. Below, the basement level provides an additional 1,091 square feet with 6-foot-tall ceilings provides exceptional storage. Ascend the graceful staircase to arrive at the third level, anchored by a central playroom/lounge with banquette seating and custom shelving. A beautiful secondary suite with a windowed bathroom overlooks the rear garden, while two more secondary bedrooms share a lovely blue-tile full bathroom. The top level of the home is a full-floor owner's retreat featuring a king-size treetop bedroom with two custom walk-in closets, additional storage, and a washer and dryer. The skylit spa bathroom impresses with a deep soaking tub, a separate steam rain shower, a private water closet, a wide trough vanity and heated floors. A large separate room on this level is ideal as a sitting room, fitness space, private home office, nursery or sixth bedroom. This home's extensive state-of-the-art upgrades include multi-zone central air independently controlled on each floor, integrated speakers, and a whole-house Tensui Water Perfection System that filters water with natural elements. A restored brick facade adds wonderful curb appeal to this one-of-a-kind Gramercy Park sanctuary. Positioned on a charming tree-lined townhouse block with immediate access to Union Square, the Flatiron District and Greenwich Village, this Gramercy Park home is surrounded by world-class shopping, dining, entertainment and nightlife. Enjoy easy access to the year-round Union Square greenmarket, Trader Joe's, Whole Foods, Fairway and Target. Local playgrounds, Stuyvesant Square Park and the East River Greenway provide outstanding outdoor space. Transportation is effortless with L, 4/5/6, and N/Q/R/W subway lines, excellent bus service, CitiBike stations, and the Stuyvesant Cove Ferry Terminal all nearby.

Gramercy Park is one of New York City’s most storied and architecturally distinctive neighborhoods, centered around the only private park in Manhattan. The area exudes old-world charm with its gas-lit streets and impeccably preserved 19th-century architecture. While the park itself is private, the surrounding real estate offers a mix of historic brownstones, elegant pre-war cooperatives, and boutique new developments that cater to those seeking a low-traffic urban retreat.
