This sun-drenched, loft-like residence in the heart of Carnegie Hill is defined by extraordinary scale, light, and classic prewar elegance. With 21 oversized windows, four exposures, and soaring 9’6” ceilings, the home is flooded with natural light from sunrise through sunset. The expansive layout offers four generously proportioned bedrooms with the flexibility for a fifth, three full bathrooms, and grand proportions overlooking Madison Avenue. A gracious entry foyer sets an immediate tone of sophistication, opening into a wide gallery hallway that seamlessly connects each room and is ideal for displaying art. The impressive 30-foot living room is perfectly suited for entertaining, featuring a Chesney gas fireplace and open views over Madison Avenue. A corner office/den, which can easily function as a formal dining room or additional bedroom, enjoys tranquil eastern and southern light. All bedrooms are wonderfully scaled and benefit from bright southern exposures. At the heart of the home is a beautifully renovated, eat-in kitchen with two north-facing windows, custom cabinetry, and a built-in banquette. Premium appliances include a Sub-Zero refrigerator and wine fridge, Thermador oven and gas cooktop, Bosch dishwasher, and a fully vented exhaust system—creating a space that is both elegant and highly functional. The corner primary suite is a serene retreat, featuring a spacious dressing room and a windowed en-suite bath with open southern and western views. Additional features include a vented in-unit washer and dryer, video intercom, central air conditioning in the primary bedroom and one additional bedroom, and through-wall air conditioning throughout the residence. Pied-à-terre and subletting are permitted on a case-by-case basis with board approval. Financing up to 75% is allowed, with a 2% flip tax paid by the buyer. There is a live-in superintendent and pets are welcome. Convenient transportation includes the 4, 5, and 6 subway lines and the M1, M2, M3, and M4 buses directly outside on Madison Avenue.
