Description

A gracious, turn-of-the-century corner residence offering three spacious bedrooms and a dedicated home office, all within a full-service building in a prime Upper West Side location. Grand in scale and refined in flow, this sun-filled home boasts soaring 10-foot beamed ceilings and nearly 7-foot-tall windows that frame peaceful, tree-lined views.

The wood-paneled formal dining room and living room sit side by side, creating a seamless space for entertaining. Currently configured as an expansive double living room, the area feels warm and inviting with custom built-in bookshelves and flexible seating options.

At the heart of the home is a beautifully renovated eat-in kitchen, featuring a butler's pantry, marble countertops, stainless steel appliances (including a 5-burner stove, dishwasher, and built-in banquette), and a striking patterned hardwood floor that adds texture and charm. Just off the kitchen is a generous home office with custom shelving and a powder room, ideal for working from home or as an overflow guest room.

Three well-appointed bedrooms offer generous storage, including a cedar-lined closet and a walk-in hall closet. The serene primary suite enjoys dual exposures, two closets, and a windowed en-suite bath.

The home also features an in-unit washer/dryer and newly installed, top-of-the-line windows. A Sonos sound system is integrated throughout, with speakers in the dining room, living room, and primary bedroom.

Built in 1912 by architect Gaetan Ajello, 645 West End Avenue is an Upper West Side gem with a grand lobby and full-service amenities including a 24-hour concierge, live-in superintendent, fitness center, private storage, and a landscaped roof deck with Hudson River sunset views. The building is pet-friendly, one block from Riverside Park, and close to the express subway, crosstown bus, top dining, cafés, and boutique shopping. A timeless home in a prime location.
