After spending some 16 years with the inimitable Parish-Hadley design firm, David Kleinberg branched out to establish his own company, now recognized internationally for superior architectural renovation and interior design. Kleinberg brought his sense of sophistication and discernment to the custom-curated and carefully rejuvenated interiors of this magnificent residence, soaring 10 floors above Park Avenue in a building designed by one of the city’s preeminent Prewar architects.

The home’s effortless floor plan spans the full floor, offering more than 7,000 square feet of impressive, generously scaled living and entertaining space accessed via a private elevator. Nearly every room benefits from plentiful natural light and enjoys unobstructed varying views of the city skyline.

The elegance begins in a glamorous circular marble foyer with decorative mirrored doors and tile inlays displaying Deco flourishes. Beyond, a grand collection of public areas unfolds: a welcoming reception room; a warm, inviting living room with a fireplace and oversized windows; a colorful dining room with eye-catching contemporary lighting; a richly hued library with bookshelves, wide windows, and a striking coffered ceiling; a family, media, and game room with a fireplace; a refined, light-filled sitting room; and a quiet, contemplative office with a wall of bookshelves. Flanking these spaces is a majestic gallery hallway with walls ideal for the display of art. A chic powder room and a wet bar are perfectly, discreetly positioned for entertaining. Chefs of any skill level will appreciate the crisp clean lines and professional-caliber appliances of the marble- and stainless-steel-clad kitchen, which features counter seating and a bright, convivial breakfast nook.

The floor plan was carefully designed to provide serene separation of public and private spaces. With windows facing in three directions, the expansive owner’s bedroom is a true retreat warmed by a fireplace and including a sitting area, two lavish marble baths—one with a soaking tub and the other handsome woodwork—abundant closets, two spacious dressing rooms—one with dazzling mirrored cabinetry—and a gym. Three bedrooms are secluded in the guest wing; each has its own en suite bath, closets, and thoughtful built-ins that range from cabinets to desks.


The cooperative at 550 Park Avenue is a 1917 building designed by James E. R. Carpenter—a student of the École des Beaux-Arts who went on to become one of the early-20th-century’s leading architects of luxurious residential high-rises in Manhattan. Pets are welcome in the white-glove building, which offers an attended door and lobby and is known for its quiet, restful ambiance.
