Description

Exceptional Space, Storage & Serenity in the Coveted Beekman Place Enclave Offering exceptional storage capacity and nearly 1,500 square feet of thoughtfully designed living space, this beautifully expanded combination residence presents a rare opportunity within the highly sought-after Southgate cooperative. Nestled within the charming Beekman Place enclave, Residence 9DE combines the scale and functionality of a larger home with the elegance and character of a classic Emery Roth pre-war residence. Overlooking Southgate's tranquil private gardens rather than the street, this is one of the quietest and most peaceful two-bedroom residences in the building. A gracious entry foyer and gallery welcome you into the home, where abundant storage immediately sets the tone. Triple exposures bathe the residence in natural light throughout the day, while oversized windows frame serene garden views. The expansive living and dining room is anchored by a wood-burning fireplace and flows seamlessly into a thoughtfully designed kitchen featuring stainless steel appliances, granite countertops, extensive cabinetry, a pantry, built-in microwave, and a charming windowed breakfast nook. The oversized primary bedroom wing-formerly an entire studio apartment-is a true private retreat. Easily accommodating a king-sized bed and sitting area, the suite features a spacious walk-in closet, a windowed flex room ideal for a home office, dressing room or den, and an updated en-suite marble bath with heated floors and dual medicine cabinets. The second bedroom enjoys corner exposures, generous closet space, and its own en-suite bath. Storage is truly extraordinary, with seven spacious closets, including three walk-in closets, plus multiple private storage units in the basement that transfer with the apartment. A rare in-unit laundry room features a Miele washer and dryer, utility sink, and additional storage space. Recently replaced PTAC units ensure year-round comfort. Built in 1931 by Bing & Bing and designed by renowned architect Emery Roth, Southgate is one of Manhattan's most distinguished cooperative communities. Residents enjoy a 24-hour doorman, beautifully landscaped private courtyard, bicycle storage, laundry facilities, and private storage. This is a rare opportunity to acquire a spacious, tranquil, and exceptionally well-appointed residence in one of Manhattan's most desirable residential enclaves.
