Description

Stately and elegant, this landmarked 25-foot-wide single-family townhouse sits poised on a picturesque tree-lined block in prime Lenox Hill. Spanning approximately 6,750 square feet across three stories, this six-bedroom, five-bathroom residence combines classic grandeur with refined modern comfort — featuring soaring ceiling heights, an elevator, and exceptional entertaining and private spaces throughout. Upon entering through a handsome foyer, you are greeted by a spectacular great room with ceilings over 12 feet, an exposed brick wall, and a dramatic skylight flooding the space with natural light. The large eat-in chef’s kitchen opens onto a south-facing garden terrace and includes a discreet powder room. A custom wine vault, second powder room, and two coat closets complete the first level. Overlooking 73rd Street, the palatial primary suite occupies one half of the second floor and boasts a bespoke dressing room and a luxurious ensuite bathroom with double vanities, an oversized soaking tub, separate shower, and radiant heated floors. A gracious gallery lined with closets leads to three additional bedrooms—one with an ensuite bath and two sharing a large bathroom, all offering abundant closet space, including a walk-in. The third floor is crowned by a sunlit Stephen Wang–designed library with ceiling heights well over 10 feet, exquisite crown moldings, intricate woodwork, and herringbone wood flooring. This level also includes a home gym, media/playroom, two south-facing bedrooms sharing a full bathroom, and a laundry room for added convenience. Modern systems include a Niles Audio sound system, Stealth Acoustic in-wall speakers, and Lutron lighting throughout. Graced by an iconic limestone and brick façade with grand double-door entry, 178 East 73rd Street represents a rare opportunity to own a historic townhouse of timeless sophistication in one of New York’s most coveted neighborhoods.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
