Perched atop 145 East 76th Street, this full-floor penthouse is defined by exceptional light, scale, and sweeping skyline views in all four directions. A private, fob-locked elevator opens directly into the residence, where 12-foot ceilings and wraparound exposures immediately create a remarkable sense of volume and openness. The home is encircled by approximately 1,150 square feet of planted terrace space, offering a rare indoor-outdoor living experience high above the Upper East Side. The wraparound terrace is one of the home's defining features, offering open views to the north, south, east, and west. Multiple seating and dining areas allow for true outdoor living and entertaining, with uninterrupted skyline outlooks from sunrise through evening. The south-facing entertaining rooms are filled with natural light and open city views, with direct access to the terrace for seamless indoor-outdoor living. The eat-in kitchen captures the same southern exposure and connects directly to the main living spaces, while a separate service vestibule with its own elevator adds functionality and additional storage. The bedroom wing is privately set apart from the public rooms and is reached through a bright gallery hallway with eastern exposures. The secondary bedroom suite benefits from strong western light, built-in storage, and an en-suite bath. The primary suite is particularly distinguished by its dual east and west exposures, allowing for natural light throughout the day. Full-height double doors open directly onto the terrace, extending the room outward and framing open skyline views. The suite also offers significant built-in storage and a spacious primary bath with separate tub, shower, and double vanity. Included in the sale is a separate approximately 410-square-foot studio with natural light and custom cabinetry, ideal as a home office, gym, or creative space. Built in 1999 in the tradition of the Upper East Side's grand prewar addresses, 145 East 76th Street is a boutique full-service condominium with 24-hour white-glove service, fitness room, children's playroom, bike storage, and pet-friendly policies.
