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.
