Penthouse living at its finest offers something increasingly rare on the Upper West Side: volume, light, and open sky at the very top of a storied prewar building. Wrapped in southern and western with sweeping views toward the Hudson River, this four bedroom with formal dining room is bathed in natural light throughout the day. Soaring ceilings elevate every room, while the classic center hall layout creates a graceful, intuitive flow between entertaining spaces and private quarters. The living room, dining room, and library unfold in a refined enfilade, where glass paned pocket doors and French doors allow the rooms to expand for gatherings or close for quiet focus. Corner bedrooms capture brilliant light and open sky, offering both presence and privacy. The overall effect is grand yet grounded, architectural yet welcoming. At the heart of the home is the newly completed kitchen, a comprehensive renovation by the current owners. Custom solid wood cabinetry brings warmth and craftsmanship, marble countertops add timeless polish, and a bespoke banquette creates a natural gathering place. All appliances are new and seamlessly integrated, delivering modern performance within a beautifully tailored space. Built in 1910 in the Beaux Arts style, the building pairs historic character with full service ease, including a full time doorman and live-in superintendent. Exceptional light, open views, impressive ceiling height, and white glove service define this rare penthouse offering, a refined sanctuary above the city.
