A Rare Convergence of Old World Grandeur and Modern Sophistication
True luxury is often found in the seamless marriage of historical soul and modern convenience. This rarely available 3 Br residence at 645 West End Avenue is a masterclass in this balance. Designed in 1912 by the esteemed Gaetan Ajello, all of the heavy lifting has been completed in this thoughtful restoration, preserving the architectural integrity that define Upper West Side grandeur while discreetly integrating 21st-century infrastructure. Every home has a story, and so does 11D, which awaits personalization on a few decorative details.
Spanning a graciously proportioned floor plan, the artisanal detail in this home is simply stunning. Original tiger oak wainscoting, Beamed ceilings, crown moldings, and hardwood inlays have been revived to their former glory, complemented by fully modernized electrical and plumbing systems.
The kitchen is a bespoke culinary space featuring original glass front full oak cabinetry with abundant storage and honed soapstone countertops. Original raised floral tile and subway tile backsplash along with dedicated space for your appliances, offers a seamless blend of historic soul and immense utility.
The flow from the kitchen to the side-by-side living and dining salons, divided by soaring french glass doors, create a warm, welcoming expansive space perfect for everyday living as well as high-level entertaining.
The primary ensuite is a sun-drenched sanctuary with eastern exposures over WEA and anchored by a museum-quality stained glass window. Remarkable storage, featuring the original shaving closet and custom cedar-lined closets including a walk in. A secondary corner bedroom with east and south exposures and a light-filled third suite with half bath, provide flexibility for a sophisticated home office or guest room. Each bathroom features an original stained glass window, and there are a total of 6 cedar lined closets throughout the home. 645 West End Avenue remains one of the neighborhood's most coveted addresses. Residents are welcomed by a stately double-height lobby, and enjoy a spectacular landscaped roof terrace offering panoramic river sunsets, a private fitness center, bike room and private storage (waitlist). Situated on a premier residential corridor between Riverside and Central Parks, 645 WEA is the perfect home for a buyer who values pedigree, light and a lifestyle of understated elegance.
