550 Park Ave Fl 2W, New York, NY 10065

Set within one of Park Avenue’s most storied cooperatives, this grand eight-room residence blends timeless pre-war architecture with the bold, expressive spirit of 1970s design. A private elevator landing opens to a sweeping marble-clad gallery, where 11-foot ceilings, soaring proportions, and streaming natural light immediately set a luminous tone. The nearly 50-foot-long living and dining room offers dramatic scale, framed by oversized windows that capture serene treetop views of the Colony Club. A sunken living area — a signature of 1970s interiors — creates a relaxed yet dynamic flow, while a cozy library nook anchored by a wood-burning fireplace adds an intimate counterpoint. Designed for modern entertaining, the chef’s kitchen features an industrial Garland range, a professional-grade refrigerator, and a spacious butler’s pantry. French-inspired details and the industrial scale of the appliances bring both warmth and gravitas to the space. A discreet powder room completes the entertaining wing. The private quarters include a corner primary suite with a large walk-in closet and a luxurious en-suite bath with a soaking tub and double vanity. A secondary bedroom offers a rare retreat: an en-suite bath with a cedar-lined sauna and a Japanese soaking tub. A third bedroom with en-suite bath and a flexible staff room complete the layout. With its distinctive sunken living room, rich materiality, and original architectural bones, the residence offers extraordinary potential to reimagine and modernize — whether embracing its vintage soul or layering in new, contemporary elements. Built in 1917 by legendary architect James E.R. Carpenter, 550 Park Avenue remains one of Manhattan’s most prestigious cooperatives, offering white-glove service, up to 50% financing, and a 3% flip tax paid by the buyer.
