Description

A Rare Riverfront Classic Top-Floor Living with Spectacular East River Views Tucked behind a private, attended gatehouse on a quiet East 51st Street cul-de-sac, Beekman Terrace is one of Manhattan’s most distinctive residential enclaves. Designed by Treanor & Fatio and commissioned in 1924, this intimate prewar residence welcomes you through a lush, European-inspired courtyard garden, offering a rare sense of privacy and tranquility along the East River. Perched on the coveted top floor, Apartment 6B is a sun-filled, thoughtfully upgraded two-bedroom home with sweeping river vistas and expansive eastern skies. The generous living room features a wood-burning fireplace, custom built-ins, and a deep window seat perfectly positioned to enjoy the ever-changing waterfront panorama. An inviting dining area continues the views, while the well-appointed kitchen offers stone countertops, ample cabinetry, and quality appliances. Classic prewar elegance meets modern comfort throughout, with high ceilings, herringbone oak floors, a gracious gallery entrance, and a windowed bathroom with a deep soaking tub. The peaceful primary bedroom offers excellent closet space, while the second bedroom, framed by French doors, makes an ideal guest room, den, or home office. Residents enjoy a 24-hour doorman stationed at the gatehouse, a fitness center, central laundry, and the dedicated use of an individual storage bin. Just one flight above, the spectacular landscaped roof deck offers another exceptional vantage point over the river. Steps from the East River Promenade and Peter Detmold Park, with convenient access to the E, F, and M subway lines, this special home combines waterfront serenity with Manhattan convenience. A timeless prewar classic, a private garden setting, and a front-row seat to the East River — a truly special place to call home. Pets welcome. Pied-à-terre and trust purchases permitted. 2% flip tax payable by purchaser. Maximum financing: 65%.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.

How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
