Description

Grand, elegant, with loft-like scale, this high-floor corner 4-5-bedroom residence offers generously sized rooms and beautiful prewar character throughout. Light pours in from four exposures, with protected open city views. Located just one block from Riverside Park, the apartment sits in one of the Upper West Side's most charming boutique full-service prewar co-ops. Apartments of this scale, light, layout, and condition rarely become available in this prime Upper West Side location.
Fully renovated, the home currently offers four spacious bedrooms plus a staff room or home office and three-and-a-half bathrooms within a classic prewar layout designed for both gracious entertaining and comfortable living. The floor plan features a dramatic entertaining wing and two private bedroom wings, creating a balance of openness and privacy.

Nearly 10-foot ceilings, oversized windows, hardwood floors, and elegant moldings enhance the home's classic character. Modern upgrades include multi-zone central air conditioning, a smart home system, built-in audio speakers, a full laundry room, and abundant custom closets. Pocket doors allow spaces to open for entertaining or close for privacy.

Entertaining Spaces: The formal living and dining rooms span more than 35 feet, creating a spectacular setting for large-scale entertaining, with a pocket door allowing separation for intimate gatherings. Large windows frame open city views, bringing light to the entertaining rooms and the expansive entry gallery. Beyond the formal spaces, the home opens to a sun-filled den/media room and beautifully renovated kitchen, creating nearly 30 additional feet of gathering space-ideal for everyday living or casual entertaining.

Kitchen: The renovated eat-in kitchen is designed for both day-to-day and serious cooking. A center island opens to the den while maintaining subtle separation. Custom cabinetry, stone slab countertops, and thoughtful design details include a butler's pantry, breakfast bar area, and built-in home office workspace. Top-of-the-line stainless steel appliances include a Sub-Zero refrigerator and Miele oven, cooktop, vented hood, and dishwasher. Just off the kitchen is a powder room, a windowed home office (formerly the staff room), and a separate laundry room with full-size Miele washer and dryer.

Bedrooms: The private bedroom wings offer comfort and privacy, with four generously proportioned bedrooms featuring oversized windows and excellent closet storage. Two bedrooms enjoy corner exposures, bringing in beautiful natural light and open views. The primary suite is impressively scaled, with a large walk-in closet and a beautifully appointed en-suite bath with a seamless glass shower. It enjoys open city views with a peek of the Hudson River, and a western exposure that provides lovely afternoon light and spectacular sunsets. All full bathrooms feature Duravit sinks and either glass-enclosed showers or deep soaking tubs.

Designed in 1918 by architect George F. Pelham, 270 West End Avenue is a sought-after prewar cooperative at the corner of West End Avenue and 73rd Street. Originally built with just 35 residences, the building offers the scale and privacy of a boutique cooperative. The 13-story cooperative features a 24-hour doorman and elevator operator, live-in superintendent, basement storage, bike room, and common laundry. Pets and pieds-à-terre are permitted.
