Enjoy stunning Riverside Park and Hudson River views from five rooms of this elegant nine-room home. Expansive windows fill the apartment with bright, airy light that shifts beautifully with the seasons. Eleven windows overlook Riverside Park and the iconic Soldiers' and Sailors' Monument, capturing glowing sunsets over the river to the west and abundant morning light from the open eastern exposures. Apartment 6D is one of the most sought-after layouts in the building - a grand classic nine reimagined into eight rooms spanning approximately 3, 000 square feet. A sweeping central foyer leads to an ideal floor plan with four bedrooms (currently configured as three plus a library) and three full baths. The large living room and bedrooms face west toward the river, while the formal dining room, office, and oversized kitchen face east. The layout offers a wonderful balance of formal entertaining areas and private living spaces. One of the largest homes in the building, 6D was beautifully renovated by its NYT-published architect/owner, an Architectural Digest Pro (AD Pro). The home was also featured on NBC's Open House NY, showcasing its refined design and craftsmanship. Elegant prewar details-high ceilings, pristine moldings, and original hardwood floors-blend seamlessly with modern luxuries: a stunning expanded eat-in chef's kitchen with top-line appliances and butler's pantry, through-wall A/C in most rooms, en-suite baths, washer/dryer, and excellent storage. The custom-designed kitchen features premium finishes and professional-grade appliances, including a Wolf six-burner range with vented hood, Miele dishwasher, and 48 Sub-Zero glass-door refrigerator. A central island and extensive cabinetry provide generous space for cooking and entertaining. 173-175 Riverside Drive, designed in 1926 by J.E.R. Carpenter, is a distinguished prewar cooperative with 24-hour doormen, handymen, porters, and a live-in resident manager. Amenities include a fitness center, storage and bike rooms, laundry facilities, a playroom, and a recreation room. Highly regarded and pet-friendly, the building fosters a welcoming community.
