Property Description for 865 First Ave, 9-C

Right next to the United Nations, in one of Midtown East's most distinguished prewar condominiums, Residence 9C is a sun-filled one-bedroom, one-bath home with double exposures East and West — and the gracious proportions of a bygone era. The spacious living room a rare and tranquil backdrop that changes beautifully with the light throughout the day. The oversized bedroom is tucked away from street noise and opening onto quiet, leafy views that feel worlds away from the city below. An oversized welcoming foyer sets a gracious tone from the moment you arrive — generous enough to serve as an entry gallery, home office, or library. The windowed kitchen is outfitted with custom cabinetry, granite countertops, a Sub-Zero refrigerator, stainless steel appliances, and natural stone floors. Original architectural details including high beamed ceilings carry throughout the residence, lending warmth and character that newer construction simply cannot replicate. 865 UN Plaza is an elegant, pet-friendly full-service condominium, offering a 24-hour doorman, live-in resident manager, central laundry, bike storage, and a beautifully appointed slate-floored lobby. Surrounded by the UN Rose Garden, East River Greenway, and Peter Detmold Park, with convenient access to Grand Central, the FDR Drive, and the Midtown Tunnel. Residence 9C is a rare opportunity to own a corner home of genuine prewar character in one of the most quietly remarkable addresses in Midtown East.

Turtle Bay | Manhattan

Quick Profile

Turtle Bay is best known for hosting the world’s dignitaries at United Nations once a year as the world institution sits on the eastern edge of the neighborhood along the East River.

But this midtown location offers a lot more, a bustling neighborhood teeming with high-rise apartment buildings and an easy walk to the Midtown business district.

Over the past two decades, developers have assembled almost every corner development site along Second Avenue and have built straight up. Not much left to assemble.

Some of the more glamorous, and of course most expensive, addresses are in close proximity to the United Nations. Trump World Tower, which caused a big stir with area residents, in particular, Walter Cronkite, when it was built sits just north of the United Nations Grounds. 

In contrast to the proliferation of the residential highrise, Turtle Bay does have some lovely tree-lined streets between the avenues. In particular, Turtle Bay Gardens, which fronts both 48th Street and 49th Street between Third and Second Avenue has always been a haven for the rich and famous.
