Experience the pinnacle of privacy at 441 East 57th Street. Arrive via keyed elevator directly into your 9th-floor foyer, where this 1,716-square-foot duplex unfolds across two levels of architectural brilliance. The Great Room immediately commands attention with soaring double-height ceilings and a dramatic wall of south- and east-facing windows, framing cinematic views of the East River and Sutton Place Park. The windowed chef's kitchen is a masterpiece of form and function, featuring Calacatta marble, a professional-grade La Cornue range, and a suite of Miele and Viking appliances. While the upper level hosts a bright, en-suite secondary bedroom, the lower level is a dedicated primary retreat. This expansive sanctuary offers sun-drenched southern exposures and a spa-inspired bath complete with a deep soaking tub and rainfall shower. Designed by Flank Architects, this boutique condominium represents a rare fusion of ultra-modern glass aesthetics and historic neighborhood charm.
