Not for purchasers with no or little imagination. This sprawling full-floor unit has not been renovated for decades. Still, the layout easily evokes the bygone time in New York history when one had weekly catered dinners wherein dignitaries, the intelligentsia, the socialites, and the philanthropists mingled freely to discuss issues of the day. From the roaring Jazz Age to the swinging “disco fever” 70s, to the punk rock culture of the 80s and 90s, one can visualize how the gracious rooms of this incredible apartment could have accommodated all effortlessly. Even after years of vacancy, one can still feel the joie de vivre that flows from room to room. Originally 13 rooms converted into 10, the residence offers the new owner a chance to create four, five, even six bedrooms without taking away from or substantially limiting the entertaining space!
Current layout:
The elevator opens onto a private vestibule that offers both security, privacy, and practicality. Proceeding further, one finds a spacious gallery and corridor with an expansive display wall that’s an art lover’s dream. Here, one also gains access to key service, entertaining, and living areas.
The bright corner living room, facing north and east, is truly a grand salon. Nearly 550 square feet with a wood-burning fireplace, it offers plenty of room for multiple seating arrangements perfectly suited to today’s style of entertaining. The adjoining formal dining room is nearly 400 square feet. That’s more than enough for a large gathering of family and friends AND social distancing, whether you have to or you simply want to (almost everyone has a weird cousin...)
The windowed kitchen efficiently consists of a main working area plus a breakfast area or butler’s pantry, The rooms that follow were originally four maid’s rooms that are currently a staff room, a mechanical room (for HVAC), and a media room.
Across the hall facing Park Avenue are the living room, library with bath, two supplemental bedrooms, and baths. Rounding it off is an enormous primary bedroom with an insane amount of closets, a dressing room/gym, and two primary baths. The current floor plan shows west-facing windows that are currently covered but can be restored.
This grand residence is not for everyone. It is for a purchaser who is looking for a special project, who can get past the aesthetics, who can see the brilliant sparkle on a diamond that has just been unearthed. Bring your architect. Bring your contractor. But most of all, bring your passion. Because that’s what will make this amazing space truly magical.
Built-in 1925, 510 Park Avenue is a premiere cooperative originally built by Starrett Brokers and designed by F.H. Dewey & Company. With only 26 residences, it is considered boutique by New York standards. The co-op features a fitness center and bicycle room. Located just at the cusp of the Upper East Side, it is ideally located near the best-established restaurants, galleries, and boutiques in New York as well as the flagships of the biggest global fashion and jewelry brands. It is a stone’s throw away from Central Park, and a flaneur’s delight.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, 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.
